GeForce GTX 970 SLI review - Product Showcase

Product Showcase

For today's article we make use of GeForce GTX 970 cards and though you might just have read our reference article.
 

Each GeForce GTX 970 will come with 4 GB of graphics memory, that's definitely enough if you are a hardcore gamer with a monitor resolution of 1920x1200 and upwards to Ultra HD. If you plan to game on triple monitors then actually 4 GB starts to make a bit more sense as this will definitely help you out in the uber high resolutions and with hefty AA combinations.

The GeForce GTX 970 has a maximum power consumption of 165 Watts, you'll need to power the card with two PCIe PEG leads from your power supply per card. We recommend a 700~800 W power supply to start with two card. We need a little extra Wattage for efficiency, but you also want a little reserve if you plan to overclock processor or the GPUs. Extra voltage can really eat away in your power consumption fast.

The GeForce GTX 970/980 PCB itself is based on a 4-phase power design for the GPU with an added phase for the memory subsystem. The card is PCIe Gen 3.0 compatible. Going from PCIe Gen 2 to Gen 3 doubles the bandwidth available to the add-on cards installed, from 500MB/s per lane to 1GB/s per lane. Like any high-end GeForce graphics card, Nvidia will allow you to opt for the multi-GPU road as you may pair two or three cards in one PC -- heck even four if you are up for a daunting task of course.
