Well, I'll let you guys know what I did first, after normal installation.
I wanted to try out the proc. However I thought I had everything to compile mame. Nope. Since I couldn't do that I decided I'd try out the video card. The first thing I ran is not on the pol

I ran quake3 with everything on. Man, that is beautiful. You realize with my old PIII and ati 128 I had to turn most everything off, including modelling the weapons in the playfield.
Then I ran Stepmania to try the TV out with my dancepads. Neat! WIll have to get the right cables to hook up my computer to my home theater.
I found something to stress the proc (I've been doing temp readings lately). I am using Dancing Monkeys. It's a program that generates steps for stepmania by analyzing the song. Very CPU intensive. Pretty cool stuff. What use to take my 15-20 minutes now takes a couple of minutes

My next goal is to make the system run dead silent during idle. Through researching looks like I will be purchasing a Silenx 80mm thesistor case fan, Silenx PSU, Silenx GPU Cooler, Silenx HDD Cooler, possibly Silenx CPU Cooler if it fits my mobo, and a Zalman northbridge heatsink. Along with Artic Silver heatsink compound of course.
The goal is to get the system as cool as possible during idle so the psu and case fan run as low rpm as possible. If the 120mm Silenx cpu cooler can fit my mobo that will be pretty quiet since it uses a 120mm fan.
