Well. I was looking at playing Unreal 3, Counter Strike, Crysis, Call of Duty, World of Warcraft and, Everqeust 1.

I dont think that 1 GTX285 can do Crysis. can it?

Crysis is just one game, pretty costy to get that little FPS more for one game isnt it?
A 285 appears to do fine, although I dont know the resolutions etc.

35fps is not enough. Good frame rates is 100fps and 60fps minimum.
 


I think the human eye can't tell the difference beyond 60fps.

And 30 is the required fps for a first person shooter, so it's good enough. Anything beyond 60 is for benchmarking only.

Anything over 60 fps is adequate, 72 fps is maximal (anything over that would be overkill). Framerates cannot drop though from that 72 fps, or we will start to see a degradation in the smoothness of the game. Don't get me wrong, it is not bad to play a game at 30 fps, it is fine, but to get the illusion of reality, you really need a frame rate of 72 fps. What this does is saturate the pipeline from your eyes to your visual cortex, just as reality does. As visual quality increases, it really becomes more important to keep frame rates high so we can get the most immersive feel possible. While we still may be several years away from photographic quality in 3D accelerators, it is important to keep the speed up there.
Looks like 3dfx isn't so full of it.

GTX 295 is 2x240 sp (same as 2xGTX280) at clock and memory amount and interface (2x) of GTX260...so 2x GTX hybrid between 260 and 280

well guess what?
u wont get 60fps with 285 sli at very high.... maybe not even with high...
its crysis... its a cool game with a screwed up engine...

not two 260's but a hybrid between a gtx260 and gtx280. just the memory and core clock speeds are from a gtx 260 but everything else from a gtx280. All reviews show this at the beginning...

I disagree about 3 285's beating quad 295's...

They both have their advantages and disadvantages list from the link...

Just getting one of these GTX295 was already hard enough...

this doesnt make any sense. Are u saying??

what a joke.

GTX260 and GTX 295

SAME clock
SAME memory interface (x2)
SAME memory size (x2)
ROP 28 (x2)

Different Processor core (240 vs 192 or 216) from the GTX280

GTX280 have 32 rop

all of those have 1400 transistor
