570SLI needs larger frame buffer at 6144X1152 (NVsurround)?
 
570 SLi seems to not have enough vram to game at that res. :doh: One of my favorite games to play is Dirt2 and soon to be Dirt 3 (I assume). I thought that Dirt2 would be awesome with NVsurround. I tried playing yesterday and my FPS are not good. I turned AA off and even started to lower other settings to no avail. I need 60 min FPS constant not 30ish.

I am not sure what to do now, get 6950 2GB CFX or just get a U2711, keep the 570 SLI and ditch multi panel gaming? Look at the rest of my system specs, you will see that they are not at fault (IMHO).

What do you guys think?

A GTX570 SLi has more graphics processing power than a HD6950 Crossfire. At that high of a resolution you definitely need more VRAM to cope with the extra resolution. Your GTX 570 has only 1.28GB of VRAM and not 2.56GB combined.

If you could afford a HD6950 2GB CF then you might as well go all the way for a HD6970 2GB CF. It has definitely more performance than the GTX570 and HD6950.

6970 CFX is too expensive TBH. As well I would like to hear from eyefinity users first hand if the 2GB on AMD 69XX cards will be enough for 6144X1152? Lastly another concern that I have with a move to AMD is that from what I hear AMD drivers are not all that good and I do NOT want to mess with crap drivers regardless of the brand.

I am thinking that I should just go with a U2711 and forget NVsurround/eyefinity. AFAIK my 570 SLi should beable to handle 2560X1440. According to video card reviews at HWC this seems to be true.

Please continue to give me feedback concerning these issues. Thanks

Phill is right in assuming his problem. I have the same issue with my 560s and very high AA in nvidia surround in Dragon Age 2, the 1GB doesnt have enough buffer to handle it all, whereas your 1280MB 570s have the same issue for your game. The 6970 crossfire would potentially lead to better performance at the resolution due to more memory being able to be address/used at the same time compared to your 570s.

so what would be best then? get the U2711/one large display or pony up and get 6970 CFX?

Phill March 24, 2011 03:48 PM

I am leaning toward one big display

Arinoth March 24, 2011 03:52 PM

I've done the one big display, sure it was 1920 x 1080 on a 32" LCD TV, i absolutely love multi-monitor gaming instead (and i'm done to 21.5" monitors) and could never go back to single big monitor gaming. Hell whenever i'm doing work or reports i typically have all three monitors filled with information as its nice to not have to tab through things, rather have it all being displayed visible at once.

Phill March 24, 2011 04:04 PM

so does that mean that when you are not gaming you activate all displays or do you leave them spanned and then just window everything?

As well I must say that when I mention getting one big display I mean that in terms of gaming. I will still have more than one for all other types work. Generally I like at least one in portrait mode.

I borrowed a single a 6970 from my cousin and it alone is better than my two 570's in SLi in Dirt 2. This simply confirms what I already suspected/knew. :(

yeah u pretty much correctly analysed ur problem and possible solutions. basically it all comes down to u weather u wana keep multi display and go to amd or stay with nvidia and get a single better display! this is just a preference choice, not something with a right or wrong answer...
