Are you on any knd of budget?
Irregular Joe, what you have here, is a good gaming rig. You said this is primarily for photo editing? What is it for secondary? If it wont be used for games, I'd say the 8800GT is overkill. For photo editing id want a good CPU and a decent amount of RAM. The CPU you have is really not nesesarry, but if you aint on a budget, keep it.
Also whats with the Arctic Cooling? You planning to overclock? Stock Intel will do.
Lol maybe im just jealous of ppl who can afford this stuff, but IMO everything is fine, exept for the display card being overkill.
