not really no......only at greater resolutions does the 640mb take the lead.

Other than that not really.

But for DX10 i'm guessing 320mb won't be enough, so i wouldn't buy one anyways.

Yep, the 640mb has ofcourse more MB's, but it's also better in performance. There are a lot of benchmarks you could search for.

the only thing i really saw it take the lead in was the performance for Lost Planet.

But the coding for that game was aweful anyways

Hhmmm I've seen a lot of 2900XT benchmarks with 8800gts 640mb,320mb and gtx. And most of the time ofcourse GTX was first, 2900xt second 640mb 3th and 320mb 4th. That's why I said it, but I could be wrong

Click here for one of those benchmarks I was talking about

In higher resolutions in DX9 the 640mb out does out do the 320mb but nothing the human eye could tell really but due to the memory size in DX10 yes the 640mb will blow away i believe the 320mb just due to its memory you could always buy the 320mb and then step to the 640mb.I didnt like the those lost planet benchmarks they freaking scare the hell out of me. If im going out to buy a $300 plus gpu and not get good performance out of DX10 im gonna be mad along with alot of people.
