Asus Crosshair IV F
I'm planing to buy another 1TB HDD and upgrade my graphic card. What I have in mind is 5850 CFX - 6870 CFX or even 6950 CFX if possible. I now the performance of those are quite different but I'm not sure which one should I go since I do not know if my PSU is efficient enough. Tell me what you guys think; any thought will help Thanks
Another 5850 would provide a nice boost for you and your PSU has plenty of juice to support it, i would definitely take another 5850 over selling off the current one and picking up 2 6950s, it will perform reasonably similarly for less.
