About to order, opinions please

ok, im going to order this afternoon, just need a final check over, ive already got my monitor and GPU (8800 GTS 640)

Asus P5K Deluxe wifi, £145

Will buy processor on July 22, will use an old one as a stop gap until then
As my mobo supports 1333fsb, should i get one of the new 1333fsb processors over the 1066 e6600? is the difference going to be that great?

Corsair XMS2 800 2GB 5-5-5-15, £65

Corsair HX 620W, £97

Western Digital 250BG 7200RPM 16MB, £42

Thermaltake Tsunami Dream W/Window Black, £75

Samsung DVD +/-R RW 18x SATA, £20

I would go for 520W version of that PSU, if you want to save some money.

I'm sure it will still be plenty, but if you're not bothered about the money, keep the 620 just incase!
