I have heard that xfi xtreme gamer sound cards have problems with vista and so I am going to wait until better drivers come out and use on-board sound for now.

Now this is a rig that i want to OC at some point, i will probably try to just get it together and get it running stable for a little while and then try my hand at OC'ing. One thing I am worried about with oc'ing is the cooling. Also I really dont know much about the proper voltage and tweaking needed for OC'ing. Any good online guides out there?

I have also chosen the ASUS mobo instead of the EVGA one because newegg reviews said that ASUS' manual is very comprehensive and easier to install (simple and easy is a must for me at this point).

I plan on running the HD's on a raid-o configuration....if i can get it set up correctly that is. Does anyone have any experience with setting up a raid configuration on vista? how does that work? Do the drivers and everything come on the disk?

Lastly, I am a gamer, playing cs source at the moment while waiting for other games to come out. i want this computer to have optimum performance on source and be able to run future games on high settings as well. Just somethign to keep in mind when critiquing this build.

So i really just want feedback/suggestions considering that I am really new to all this and im sure your guys' knowledge far exceeds mine.

Thanks in advance for any input/advice!!

Thanks...I just ordered it...cant wait till the bad boy ships
