Just go with the x1900 it's plenty of power for anything you'll want to play anyway. Here's the 1900 I picked out for myself; note the $100 MIR http://www.newegg.com/Product/Product.asp?...N82E16814127206
oh wow for about $300, its really good deal. thx. but actually i was wondering if i should wait for GDDR4 or not.
Well that's all up to you, obviously GDDR4 will be better, but this one here is still pretty nice and you won't have to wait for it.
