Re: Final Decision
Why not Crossfire when you have a crossfire ready board and a powerful enough PSU? Crossfire/SLI is a lot better than it ever was now.
I honestly would go crossfire 4870's which will beat out a single 285GTX by a lot which are around 315 bucks.
However a 2850GTX is the most powerful single card you can get
E6300 w/ Arctic Freezer Pro 7 @ 3.6ghz 1.4Vcore
Antec 900 Case
EVGA 750i FTW Mobo
4x1GB of G.skill DDR2-800
2 8800GT in SLI
22" Samsung Syncmaster
1 250GB WD and 1 Seagate 7200.10 in RAID 0
Corsair 520HX 3DMark06 Score: 13900
