Hey pez, I just came over here from sli club forum and found out some interesting tid bits regarding gpu's resolutions and memory bandwith. here is a copy n paste from over their and a link to the thread if you can view with out joining. worth a try. http://forums.slizone.com/index.php?...ic=24853&st=20

I think its mostly because review sites are trying to compare to ATI hardware. And when you consider the vast difference in what Nvidia and ATI users use when it comes to high quality image settings. I think its a rather futile effort. I think most Nvidia users will/should aim for base 16x CSAA performance. Its the best perf/quality mode that exists on Nvidia hardware. And 16xQ being the high end, I point this out mainly because I want people to know that 512 megs can be a limitation. If you game @ 1600x1200 and lower and mostly use 16xCSAA you probably wont have much probles with existing games. As the resolution increases the problem with increase as the framebuffer usage increases,
When I did my 9800GX2 and 9800GTX Standard comparisons I tried to point out that 512 megs could be a bottleneck in some cases ((Like the example I used)) but I apparently was not as clear as I should have been because alot of people came back and asked me why they couldnt run the same settings as their old 8800GTX SLI setup. And as high end SLI users. Most of us care about high end settings. I wanted to make it more clear this time where these problems could occur. 9800GTX/9800GX2 are GREAT cards provided the memory doesnt run out. But once it does. Their performance plummets and no amount of SLIIng can fix that problem.
Basically. I was just hoping to arm users with better knowledge regarding this issue. And personally this is a very large reason why I think so highly of the GTX 260. Yes I have GTX 280 SLI cards and mostly use those. But I can barely tell the difference 90% of the time between my GTX 260 SLI and GTX 280 SLI configuration. I currently have 1 GTX 260 stored away. Its a hot summer here
The moral of this story is. I have seen a Quad 9800GX2 get over 111 FPS in that same spot at 16xCSAA/16xAF. If your getting 111 FPS. The very first instinct i have as an SLI user is to raise the AA settings to 16xQ or something. But when I turn on 16xQ in these settings it drops from 111 FPS to 3 FPS. And thats just discouraging. All that rendering potential to be bottlenecked by its memory. And I dont want anyone here to think I am downplaying the 9800GTX + or 9800GX2 hardware. They are great cards. Thats why I sent exitios Quad 9800GX2 cards. Because I knew he'd be happy with them. But just that there are certain things they cant do that the 260/280 and 3 way 8800GTX setups can.
If I was giving awards or badges away the 9800 GTX + or GX2 would get runs 16Q AA at 720p perfectly in general. And there are lot of 720p monitor users worldwide.
GTX 260 with the price drop covers 1600-1920 with slight fps drop vs 280. 280 is there for 1920x1200 and even XHD even for crysis. As a freind pointd out natural mod and crysis and 16x AA work in XHD in Crysis. And with warhead taking many ideas from natural mod thats the crysis expansion covered
I have explained on several forums that the new ATi cards are rather good and if you like ATI then the new cards offer value and performance, but the bit 99% of review sites missed is the superior memory bandwidth of the GTX series and VRAM allows 16x AA and AF at almost any res depending on how may cards you run.
ATi to save cost did the 512 Vram issue that Nvidia did with the 9 series, so if you are going to buy 1920x1200 or XHD then 95% of the cards on the markets are just no good vs the GTX series. Even if ATi or Nvidia do add 1 GIG vram to the 9 or 4 Series it does not solve the memory bandwidth issue at HD with AA/AF.
Even at lower res if you pump up AA?AF mot cards start to stall, the GTX series are the first card that appear note even to notice when AA is on or off!
A few months ago there would have been 1-2 monitors for XHD on that page, now there are 7, they are beggining to enter mass production and prices will drop just like 1920x1200 did 2 years ago. Once they hit Â£400 or lower alot of people will move to XHD, but unless they have GTX's they are in for a shock.
Some people will say you dont need AA or high AF at XHD. To that I say please view 8-16x AA and 16x AF at XHD vs no AA or AF....

maybe this helps a little when considering the type of resolutions you are considering.
