What RAM for P5W DH Deluxe? | Corsair | G.Skill | GeIL |

CPU - E6600
HSF - Scythe Ninja Plus (with 120mm fan)
MOBO - P5W DH Deluxe (intel 975x)
GFX - HIS ATI Radeon X1800 GTO ICEQ3 (to be flashed to a X1800XT)
PSU - Seasonic S12-600W
HD - Hitachi T7K250
CASE - Jeantech Phong II

All the above have already been ordered and are making their way towards me now. They are exactly what I need from this machine; the GFX are plenty for me, I only play WoWarcraft and the CPU needed for Vid/DVD encoding.

I went for the mobo as it will allow me for X-Fire sometime in the future.

Only component missing is the RAM, and thats why im posting here, I need a little help choosing.
I know I want 2x1Gb. I know I want 800mhz
I read Wusy's post about C2D OC'ing and the recomendation for "DDR2-800 4-4-4-xx good for 500Mhz+"

I am also worried about reports of ASUS boards being picky about RAM makes.

Picking from a good UK supplier I have found the following options:
