Hey guys, I’m going into my first computer build kinda blind and I wanted to know if you would help with the build sheet. I’m building a gaming system and I want to do it right the first time but also don’t want to spend any more then I need. The parts I’m thinking of are:

Asus A8V Deluxe
AMD 64 3500+
XFX GeForce 6800 GT
Hitachi 120 GB 7200 SATA
Two - Corsair 512 mb XMS
Aspire X-Navigator case

That was the build I thought of using a AGP card. Does it all work together, anything not look right? Also, is it worth switching over to a PCI Express modo and video card now or should I wait. Lastly, would it be worth it to add a raptor 10,000 rpm HD for windows and my games? I know these are all noob questions but thanks for any help. Being my first build, I just hope I’ll be able to put it together myself.
