I hope you are kidding.
The rig I listed will max most games, there really is not any point in getting more power than that for most people. Also, you need a displayport->DVI converter to run three monitors, and a BD-RW drive is pointless right now. That mobo will bottleneck quad CF 5970s too. 890GX is only x8/x8, and that absolutely requires x16/x16 or else you will lose about 10% of your performnace, possibly more. 790FX is the only real option.
3 28" hanns g monitors is pure epicness though. That is my current setup.
