On my current setup (Q6600 @3.0, 8gb ram, 4 older raptors in software raid), I can run all 6 but it is very sluggish and the processor is very close to saturation. It is playable but I would like the extra headroom on the processor. I should be able to do all 6 very comfortably with the I7 and a mild overclock. I should be able to turn up the master's graphics enough to see spell effects and such.
