Medium End

PC Buyers Guide Medium End
Target Resolution: 1600x1200 or 1680x1050

This guide will only cover the box. Monitor, keyboard, mouse and speakers are not included. I do this for brevity's sake, as the monitor alone would require its own guide, especially if I were to cover LCD monitors. Since this site is called "Guru3D" this guide will target a system intended for gaming primarily. So what sort of criteria do I take into account when deciding what parts to recommend?

  • Price and Performance: First and foremost, what gives the most bang for your buck, in terms of gaming primarily of course.
  • Reliability: Second on the list but just as important. This includes things such as compatibility (ever had RAM that worked on one motherboard but not in another?), trustworthiness of a brand overall (do they have a history of making reliable parts?) in addition to the reliability of the part in question.
  • Overclockability: Overclocking can help squeeze out that extra performance out of a system and can make a big impact on price versus performance (why should you buy a $1000 CPU if you can overclock a $200 CPU to match it?) so this factor can always swing my decision.
  • Heat and Power Issues: Heat is the enemy of a computer and it can affect the stability (and reliability) of your machine. Performance per watt has become a buzz word and as power requirements for computers rise I eye this more and more closely.

For those wondering about "Target Resolution," instead of listing a particular pricepoint (since price will vary somewhat with vender/e-tailer) I have listed here what type of resolutions you can expect to be playing most of today's games (with AA and AF on of course) on such a rig, both standard and widescreen resolutions were taken into consideration.

Processor - Intel Core 2 Duo E8500

core2duologo.jpgThe latest Wolfdale core has brought even more improvements to the already excellent Intel Core 2 Duo family. These improvements include shrinking down to the 45nm manufacturing process, additional SSE 4.1 instructions and increased cache. The choice over dual-core versus quad core is a little controversial here. But a faster Dual-core will get you more game performance than a slower quad-core. If you however do a lot of multi-media stuff .. go with a nice quad core. It's a bit of a mixed bag really. But purely for gaming, the E8500 offers extremely good value for money.

Heatsink and Fan - Noctua NH-U12P

The stock HSF will provide sufficient cooling power for a Core 2, but you want to treat your CPU right don't you??? Here is a monster of a cooler for your CPU (and I do mean monster, make sure your case and motherboard will support this beast) that will offer hands down some of the best and quietest air cooling available for your processor.

Motherboard

asus_p5qpro.jpgWhat to look for when buying a motherboard, regardless of chipset or processor it supports:

  • Good chipset cooling. Chipsets these days continue to run hotter. Better cooling means improved stability, improved longevity and better overclocking potential. Be mindful when using a passively cooled motherboard (even one with the works, including copper heatsinks and heatpipes) to ensure that you can provide the coolers with adequate airflow.
  • Solid state capacitors. Offers improved longevity and heat resistance as well as avoids the dreaded "leaking" capacitor problem.
  • Improved voltage regulator. Does the motherboard use a 3 phase voltage regulator or something higher? How do you determine the phase you ask? It is determined by the number of MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) used. As a rule the higher the number (and hence the phase) and quality of the MOSFETs, the cleaner (higher quality) the voltage delivered to the CPU, offering improved stability and overclockability of the CPU and improved thermals for the MOSFETs. Many motherboards now feature heatsinks to cool the MOSFETs as well, always nice.
  • Features. What features do you need? Chipset features vary broadly as do features individual motherboards may offer. Do you need RAID? If so what type? If you chose to use onboard sound then take a close look at the audio chipset and its associated features as they differ widely. If you want a SLI setup you will need a an nForce chipset, but not if you want Crossfire. All things to consider.

Editor's Choice: A motherboard based on the Intel P45 chipset. My personal choice is the Asus P5Q Pro. Very clean layout, Crossfire support, 8 phase power design, good chipset cooling and all the features you would expect from a mid-range motherboard.

Hard Drive - 150 GB Western Digital VelociRaptor

It may not have the capacity but a secondary storage drive can take care of that and this drive packs the speed. Western Digital's update to their well known 10,000 RPM Raptor hard drive is quite a change. The interface has been updated to 3.0 Gb/s SATA and the capacity has been doubled. However the most dramatic change was switching to a 2.5" design normally reserved to laptops and housing the drive in a heatsink to fit the standard 3.5" design, which allows this drive to be one of the coolest, quietest and most power efficient desktop drives on the market. We want to include SSD here as well, yet the capacity is just a little too small right now.
 

Editor's Note: While I give my recommendation with only a single drive in mind there are many configurations available. Here's a list:

  • For fastest load times: 2 smaller drives in RAID 0. Drawback: reliability, if one drive fails, the data on both is lost.
  • For data reliablity: 2 large drives in RAID 1. Drawback: capacity halved (all the data on one drive is mirrored on the second).
  • For heavy downloaders: One small, fast primary drive (like a Western Digital Raptor) for Windows and applications/games and a secondary large capacity drive for downloads/multimedia (such as HD video). This is actually my prefered configuration.

Memory - 4 GB DDR2 1066 MHz RAM

If you're building a new gaming computer today, chances are you'll be installing Vista. With prices as low as they are now for RAM, no reason not to go for 4 GB and go 64-bit!oczreaper.jpg

Remember that DDR2 latencies are much higher than DDR. So always take advantage of lower latency memory. Lower latency modules will have timings in the range of CAS 4-4-4-12. Keep an eye on the default voltage for the module, the default for DDR2 is 1.8v, if the default is higher (and on 800 MHz DDR2 RAM or higher it likely is) then make sure your motherboard can support it. Also make sure if you are purchasing 4x 1 GB modules that your motherboard will support it. Don't forget to buy that RAM in matched pairs so you can take advantage of dual channel for a slight boost to performance, most memory makers now sell match pairs for your convenience.

DDR3 is now available, but at this time I would not recommend it as it is priced twice as much as DDR2 (and the performance benefits are minor). Better to wait until the price and latency on DDR3 to come down before making the switch.
 

Editor's Choice: Corsair XMS2 or OCZ HPC Reaper series. Excellent brands, excellent sticks of RAM and very good price.

Video Card - GeForce GTX 260 Core 216 or Radeon 4870 1 GB

It's been quite a while since a holiday season has rolled around and neither AMD nor NVIDIA has something new to offer. Fortunately either of these cards will offer you excellent performance for the price. Both cards will perform closely when pushed to their highest playable settings but each card holds a few advantages: The GeForce GTX 260 is more power efficient and offers PhysX support, while the AMD Radeon 4870 offers DirectX 10.1 support and slightly better AA quality thanks to its new Edge-Detect method.

Sound Card - Creative X-Fi Titanium or Asus Xonar DX 7.1

Vista has left the audio card market wide open by removing direct hardware access, thus taking away Creative's long enjoyed performance advantage thanks to EAX. Into the fray comes Asus with an excellent card for those looking for an alternative. Whatever the choice, you can at last bid farewell to PCI as both these cards are PCI-Express 1x.

Our own audiophile Brann Mitchel: Speaking of fearsome, it took all of 5 seconds of listening to the Xonar D2X to know that it is our new reference sound card.  This unseats the Auzentech X-Fi Prelude at the high end (not that we really keep track of these things) as our favorite all-around card to game, listen to music, and watch movies with.

Optical Drive - Samsung Lightscribe DVD Burner SH-223Q

There really is no excuse to not have DVD±R/RW drives, they are very cheap and reliable these days. This drive is capable of burning 22x DVD+R and DVD-R, 16x DL as well as 12x DVD-RAM and boasts a SATA interface. It is also a LightScribe capable drive. This will allow you to burn a label (or image or whatever you want) onto your disks, no more barely legible permanent marker labeling!

Case

Okay Im going leave this one open to your decision. Cases are a love-hate thing, what one person likes another will not. So go find a case you think suites you. I have a few suggestions when looking for a case. Aluminum is a definite plus; it will make your computer significantly lighter. 120mm fans are the way to go as well, ensuring good airflow in your case while maintaining a minimum of noise. A removable motherboard tray is particularly useful in cramped cases.00797746.zoom.a[1].jpg

Power Supply - 850 Watt or Higher

The power demands of the PC continue to escalate, thanks in large part to GPU's and the looming arrival of quad core CPU's. Be sure to go out and get the biggest and best power supply you can, do not skimp on the power supply! This is an often overlooked part and yet it's the source of so many computer woes. Be sure to check the amps on the 12V rail(s), you want a power supply that can handle a lot, multiple 12V rails is an additional plus (although not required, PC Power and Cooling is well known for their excellent single 12V rail power supplies). For a frame of reference: NVIDIA recommends 500 Watts with 38A on the 12V rail for the 8800 GTX. Another plus to look for is a power supply with dual fans to help with cooling. Just remember: don't try and buy a cheap generic brand to save some cash, just because it says 1000 Watts (or whatever the number is) doesn't mean it can actually handle that, sadly. Quality counts big, be sure to get a quality power supply or you can face any number of problems.

Editor's Choice: BFG ES 800 Watt PSU. Simply a fantastic power supply. Allow me to borrow a quote from Hilbert: "To this very date the BFG 800 Watt ES PSU is one of the best PSUs we have tested."
