EVGA E760 CLASSIFIED vs ASUS P6T7 WS Supercomputer

My other parts are going to be:

CPU: Core i7-960
GPU: EVGA GTX 480 SC

I realy like EVGA CLASSIFIED because it have a really good layout and 10 Phase Digital PWM but it doesn't have true 4x PCI Express 2.0 x16 @x16.

Right now I'm going with just 1 GTX 480 but later I plan to add another GTX 480 in SLI and another nvidia GPU for PhysicX, this will drop my PCIe to 16/8/8 mod and if I also get another GTX 480 or a good audio card it will drop to 8/8/8/8 mod  

ASUS P6T7 WS Supercomputer in the other side does support 4x PCI Express 2.0 x16 @x16.

I'm not going with EVGA CLASSIFIED E762 4-WAY because it's just to big to fit in my HAF 932.

Actualy there are some other feature I would like from a motherboard like USB 3.0 and SATA 6Gb/s but the only MB with this feature are GIGABYTE one and I don't like their layout.

I have to buy this PC before May so I can't wait for any new board release.

I have one more question about RAM.

At first I was going to buy CORSAIR DOMINATOR 6GB (3 x 2GB) 1600 (PC3 12800) TR3X6G1600C8D but now i see a lot of G.SKILL kits that not only cost leas but also have better Speed and Cas Latency.

Thx
