PARTS PREFERENCES: I need recommendations for a motherboard and RAM for the i7 920 CPU.

PLEASE DON'T INCLUDE REBATES IN YOUR PRICING. I DON'T PLAN ON SENDING ANY IN.

CPU:
Intel Core i7 920 Nehalem 2.66GHz - $280

Motherboard:

I'm open to suggestions. All I require is that It has six ram slots and at least 2-way SLI.

RAM:
CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333

I'm open to suggestions.

OVERCLOCKING: Yes Maybe SLI PLUS physics.

MONITOR RESOLUTION: 1280x1024

ADDITIONAL COMMENTS: My last machine was a Dell Dimension 5100 that I just kept upgrading until I couldn't stand it anymore. It is a P4 3Ghz machine, 2.5 GB ram. I primarily play WC3, COD4, Demigod, L4d, TF2, HL2. I would like to be able to play games at something above low or medium settings.

Games I am looking at purchasing when they come out:
COD4 Advanced Warfighter 2
Operation Flashpoint 2
Arma 2

I also plan on replacing my video card before December and will use the 9600GT as a physics card. Possibly a GTX 275 or 285 (with a new PSU of course).

OCZ Platinum 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory Model OCZ3P1600LV6GK - Retail $120

Combo of the motherboard you were looking at and an i7 920 $515

or

i7 920 and Asus P6T $490

In the future put something between the url tags so that it actually displays at a link. The combo with the Asus board is significantly cheaper and should do what you need it to just fine.
