Yes FLy, here in Argentina the 5870 is over 520U$s , and is not so far away of the 5850 that is in 320 U$S (this too work whit dx11) … I can get right now the 5850, but I have a P&Cool 750W, will be a waste of Power supply if I put the 5850, maybe January I will get 5870 and i will tell about performances in some games 64bits like ArmA2. (hope SOW work only whit 64bits and don’t do anything whit 32bits, that is hold. 4GBRAM are not expensive…)... and i gonna puth another 4GBRAM in 2010 i think
