New computer advice

[Brighter Hell]

It's finally time to upgrade my computer. I use it mostly for general use, photo editing, and some gaming. I'm basically replacing the guts: motherboard, CPU, RAM, and video card. The hard drive is good enough for now. Here's what I'm leaning towards:

Gigabyte EP45-DS3L motherboard
Intel Core 2 Duo E7200 CPU
Gigabyte Radeon HD 4670 video card
G.Skill 2 GB PC2-8500 1066 MHz dual channel RAM

I think I've picked out everything to match. Any suggestions would be great, but I have a couple specific questions too:

-What do you guys think of G.Skill and Buffalo RAM? I've found both for decent prices. Crucial RAM with the same specs costs $20-$30 more at the vendors I'm looking at.
-Right now I have an Enermax 460W power supply. Will that be enough to power the new system?

Thanks everyone for your thoughts.

I'd get at least 550 watts on the psu and G skill is okay, probably the best buy for the money as far as ram sells.....Buffalo NOT SO MUCH.

Crucial $14/g with rebate @ buy.com. Also, Corsair and kingston are dirt cheap. For a reliable brand PSU, 500 watts is sufficient.
