If you imagine the amount of data that your gfx card is processing as a motorway, the speed of the traffic is the memory speed and the bus size is the number of lanes. Bandwidth = bus size x memory speed. If you have enough bandwidth then great and they don't build gfx cards that are crippled in that aread but trust me, there is a point where if the memory bandwidth is too low, your gfx card performance will suffer and bottleneck the rest of the GPU.

Why do people complain about price from the ultra high end cards? You don't have to buy it, I've never had a game I couldn't max out with a £250 card, you have to be an idiot to buy a £500 card. You'll never use most of it's potential as Game software doesn't require and within a year it is dated because they've made new features that are new card only. Like people going on about needing a 780ti or whatever for 1440p resolutions..... like no, it isn't true and especially with these new low level APIs coming out. Why do you have to run games at 240hrz/120hrz or whatever? I've got a 120hrz monitor and I see no difference in gameplay between that and my 60hrz one in CS:GO or any Racing Sim I play. I'm just convinced people buy into numbers and convince themselves it looks better or something. The only thing they're probably seeing is latency has to be less on a 120hrz panel or ghosting will appear, where the latency can be a bit higher on a 60hrz panel before you see ghosting. Once stuff like G sync becomes popular, it wont matter needing to hit a certain FPS to lock it so you don't get screen tearing any ways.

I don't like GTX 880!!! Because GM204 chip will be mid-end or bottom-high-end and have only 256-bit. 😕 But I will buy new top-end single GPU card (eg: GTX Titan 2 or GTX Titan Maxwell). 🙂 "GTX Titan xxx" is fast double precision. 😉

Funny how your title says "gtx 880 crap!" with thumbs down while you havn't even seen a review. (sorry i should have known... "don't feed the trolls")

So bus-width is not the be-all end-all of GPU performance, especially with newer or different architecture cards.

definitely. An 8bit bus would be fine if the bus speed was high enough. People shouldn't get hung up on numbers without understanding the big picture.

But you can load the vram as much as you want, but it the bus is still only got x amount of lanes, then its still going to take the same amount of time. Sure theres the 'its more effective at higher res's' argument, but then youd be limited by the performance of the actual gpu itself. if these indeed turn out to be the final product, then i still go to the 880 as the cost of a new highend is the same as the cost of the previous gens highend, the prices dont drop in NZ, they just wait until stock has sold out and sell the new release highend and last highend side by side with a $40-60 price diff.

My 680s at 7200 had sufficient memory bandwidth at 230gb's. This clocked at 7400 and most likely oc to 8ghz is sufficient.
