yea ya got me on suffixes for that one, could have sworn I noted it though but if I'm correct. 8800GS and 9600GSO should be about the same matter of fact I can't remember. 2600XT is actually ahead of 3650 believe it or not. but depends of whether its gddr4 or gddr3. 2600XT gddr4 > 3650 > 2600XT gddr3 or roughly the same. and I didn't realize they pumped out a 4650 with gddr3, my bad. and the 2900XT hmm I don't remember the performance numbers too well. I want to argue that they would be the same. 3 series was a die shrink anyway but something tells me 2900XT would have edged it out barely.
