Oh, spending over 1500 isn't a problem... if I go the Intel route I'm looking at probably EVGA x58, 6GB Corsair DDR3-1600, 2x 285's in SLI with a 300GB VelociRaptor and a 1TB Caviar Black.
If I go for AMD I'm looking at probably either a 940 BE with 2x 4870x2's or a 720 BE with 2x 4870's. Unless I get a 4850x2 I basically have to CF or SLI, I'll be running 3 monitors, so I need 3x DVI outputs.
If money isn't an object to you, then you can get those dominators, but if you look at the specifications, the OCZ's actually look better. They have tighter timings and can run below 1.65 volts, which is the limit for memory voltages on the i7. Many mobo's won't let you run at 1.65 volts, you have to run at either 1.64 or 1.66, and I have read reviews where people couldn't get those dominators stable unless they ran at 1.66v. Now 1.66v is actually probably fine, but I don't like to run anything on voltages higher than the manufacturer ok's, so its too high for me.
But the OCZ's are cheaper, and I think better ram. Dominators are overpriced IMO, although they are very good ram.
Like the advice here, the 7 series nVidia based motherboards are ridicously overpriced, they should be priced as bargain basement boards. Why anyone would buy one of these at the prices they demand is beyond my reasoning.
