I would just get the E8400 Wolfdale like Bok has. It only has 2 cores, but not many apps take advantage of 4 yet, especially games.
Motherboard looks good, are you planing on doing SLI?
4 gigs of ram if your going to do VISTA.
What case are you planning on getting? I have a Gigabyte 570 Aurora thats awesome, Bok has a CM Stacker 830 and there is a new CM Cosmo out too.
I have consider antec always as a sweet spot for quality and power wattage. I have a 650 Trio and it works great, runs cool.
