Suggest a motherboard and video card along with power supply wattage?

Im thinking about getting this PC

Intel CPU : Intel Core 2 Quad Q6600 2.4GHz
Intel CPU Fans : Spire Socket 775 Intel fan
DDR2 memory : 4GB (2x2GB) PC5300 DDR2 667 Dual Channel

Now I need this computer to do high graphic art along with some gaming so Id like to keep it as good as I can without spending a lot.

1. Is a 400w power supply enough?

2. Which Motherboard should I get(dont need dual vid cards)

Choices

PC CHIPS P55G
ASRock 4Core1600, G31
ASRock 775Dual-Vista
ASUS P5GC-MX
ASUS P5KPL- CM-G31
Biostar P43D2-A7 P35
ECS NF650 ISLIT-A

3.Which Video Card?
GeForce 9400GT
GeForce 8600GT
ATI Radeon HD 3650

Thanks for the help in advance
Should have asked which kind of vid cards too they offer in 1gb mainly but there are a few 512mb ones.

ummm ok no lol, 400w will not make it, for a quad pc you should use 650w+, esp if you are going to use a nvidia card. i list links to items that you should consider (note the mb does not have on board graphics, but since you are buying a separate one its all good). here is also a combo with a power supply and cpu, umm this is a great vido card wow (nice price too). it might be cheaper (and better) to go with an amd system?

note for vid cards what matters the most is the "Stream Processing Units"
