Asus P6T or Asus P6T delux V2.

Asus P6T or Asus P6T delux V2.
There's a 40$ price difference and I still don't understand any of the big differences between the two boards except the later has 3 way SLI @ 16/16/8. However, I'll never go over regular SLI so should I save my 40$ and get a standard P6T?
What I'm looking to put in this board:

EVGA GTX 275 896MB 448-bit DDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card

Intel Core i7 920 Nehalem

OCZ XMP Ready Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model

2xWestern Digital Caviar SE WD1600AAJS 160GB ***in raid 0***

Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive - for storage

And I have an 850W Corsair PSU I'm going to power everything with. Any help?

^I heard the Asus P6T comes with a SAS controller will I need that?^

Thanks.

main differences I think are the power phases, the deluxe has 16 to the p6t's 8.
The vrm coolers are copper fin to heatpipe on the deluxe but aluminium and one heatpipe, also the "northbridge" cooler is way smaller on the non-deluxe board, I dont think anyone would use the sas controller lol, it was removed for the v2 for compatibility.
If you are going to overclock your i7 to buggery then I think the deluxe would be a lot more stable due to better cooling and the power phases, if not then the vanilla or even the (i think) SE board would be ok, save yourself £70 and spend it on ram lol.
Im thinking about going core i7 too, I too am stumped for mobo choice, gigabytes or asus, both are recommended by custom pc, you can get both from £160-£230 and both do vanilla and uprated versions.

Good luck.
