Welcome to AT.
Ok... are you looking to get the best bang for your buck, or are you not caring at all about that? (I know some people don't care)
First off, I'd like to say that the Fatality board is waaaaay overpriced for what it gets you. You're paying for the marketing. There are NF4 based boards for $50 to $80 less that will perform just as well as the Fatality board.
Are you planning on RAIDing the raptors? RAID 0 will get you practically no performance increase. 1 raptor is plenty for that. It's much more cost effective to get a single raptor and then some big 200 or 250gig standard drive for your money.
If you're going to spend $175 on a powersupply, don't get a thermaltake. If you're not doing SLI and aren't running an insane number of harddrives, that's so much overkill. If you want a great powersupply still, try
this one and save yourself $50. A
430 watt Seasonic would still be plenty for your needs.
If you want to spend as much as you've got lined up now, you'd get much better performance in the end going with an SLI setup. If you bump down the CPU to a 3500+, drop down the PSU, drop a raptor, and get a cheaper SLI motherboard, it's probably going to be about the same final cost, but it will blow that system away in games.
If you want to get the same performance from the stuff you chose, you can do it for hundreds cheaper and still get something that's almost as fast.
As for the ram, I'm not going to make any suggestions if you're planning on overclocking. I know some good non-overclocking selections, but I'm not going to make any overclocking ones. I'll just say that money is better spent towards upgrading to SLI than it is getting ram that costs $300 vs. $100.
