I would be posting this on my upgraded PC, but one of the sticks of RAM I got doesn't work. It's going to probably be two weeks before I get a replacement from newegg.
I got a new job, so I blew some bux on some new parts:
Lancool PC-K62 case
ASRock P67 Extreme6
Intel Core i7-2600K
G.Skill Sniper 8GB (2x4GB) DDR3 1600 RAM
Kept the same PSU, HDDs, graphics card, and monitor.
I was worried that the mobo was the problem, but I'm pretty sure I got a bad stick of RAM. If I had gotten it from Amazon, they'd send me a replacement overnight, but newegg waits until you send it back.
