This is the computer I'm going to be building, I just wanted to see if anyone thinks this is going overboard. If you're asking whether or not I understand what I wrote, the answer is, "Yes." I completely understand, I've been learning this stuff for a while, and am now in a class for 3-hours a day learning to take-a-part, fix, and build computers. Plus, as an added bonus, learning the OS. Like learning how to install DOS the other day, that was fun.

Anyways, I also wanted to know if anyone has any particular suggestions for a gaming sound card. Price doesn't matter!

\\ I may respond a little late, sorry if I do //

I just read what I wrote and, "wow." Damn, I was tired.
