I'll be upgrading in the next two weeks (hopefully, baring any unexpected expenses) to:
CPU: Intel Q6600
MOBO: Abit IP35 Pro
RAM: 2GB OCZ DDR2-800
GFX: ??? (Nvidia 8800GTS or HD 2900XT. Haven't decided yet)
PSU: Corsair 520HX
OS: Windows Vista/Linux
and I'd like to move to the ESI Juli@ seeing as Creative haven't seen fit to release Vista drivers yet for the 0404.
You're prolly gonna want bigger power. I'm using 500 and it's one of the next things on the upgrade list, it's nearly tapped out. My specs are posted on page three I believe.
