First Build Input

[Ketsurui]

Hello everyone i am new to Tom's Hardware but i have ran across the forums before and found them to be very helpful. OK so i started to build my first gaming PC. I was wondering if i could get some input on what RAM and what Power Supply to get or any other suggestions would be greatly appreciated.
BTW i do plan on doing some overclocking.

SPECS:
CASE: Cooler Master HAF 932
MOBO: ASUS P6X58D Premium
CPU: Intel
i7 920
HEAT SINK: Cooler Master V8
THERMAL PASTE: ANTEC Formula 5
GPU: ASUS Radeon HD 5870 (2nd in the near future)
HDD: Western Digital Caviar Black 7200RPM 500GB

So that's where i am at so far like i said any input would be greatly appreciated.
