The 2900XT trounces the 320mb version and even the 640mb version in 90% of benchmarks with the latest drivers.
It doesn't trounce either on BioShock.

It will do once ATi sort their drivers out, just takes them longer to sort as its a Nvidia TWIMTBP game.

Ive actually been wondering about this too.
Ive always liked ATi - the X1900 series did it for me. They were solid, brilliant cards.
However, the benchmarks of the 2900XT that ive seen have been lacklustre to say the least. Judging by what ive read here though, that was to do with crappy drivers.
Im on the verge of ordering my PC with a EVGA 8800GTS 320 - should I jump for a 2900XT 512MB instead ?

In a nutshell - yes.
The 2900XT is faster than the 8800GTS. Don't let a single benchmark put you off - the 2900 wins just about all of the others.![]()

i wasn;t around these forums during the GF5 FX series release but i wonder if people defended it as much as they defend the 2900.
how far back are the threads kept on this forum?
It's not a case of defending the 2900xt, more correcting opinions.
Right now there is nothing between the 8800GTS 640MB and the 2900XT.
Facts:
1.) The 2900xt is noisier than the 8800 640
2.) The 2900xt consumes more power.
3.) Performance wise they are neck and neck (8800 better in some tittles, 2900 in others)
4.) The 2900xt performs better at 3dmark06
5.) With AA enabled the 2900xt takes a greater performace hit than the 8800.
6.) AMD are more consistent with their driver releases.
Myths / speculative opinions
1.) The 2900xt is better at DX10 as its architecture is more suited to it.
2.) With the new drivers the 2900xt is (performance wise) between the 8800 640 and the GTX (They are still very much on par as the new forcewares are quite good too.)
I currently have a 2900xt and wish i got an 8800 640 as at idle the fan is just too loud for my liking. Performance wise there is nothing at all in it,

.Why does it have to be so difficult to upgrade these days?Point 3 is incorrect, with the latest drivers the 2900 is a lot faster than the 640mb GTS.
