Well I have one of these and am happy... however, I'm really gagging to get settings maxed out on Oblivion, EQ2 and whatnot and I reckon the 256MB memory is probably the limiting factor - it's def not my E6300 as that's semi-bored running most games 
Are the 8800s worth going for and is the price likely to drop soon? Would I see much difference in getting one of these?

Who knows, you might end up with easyrider's GTX.
