The last time I bought a computer I went down to Best Buy and bought what I though at the time (about two years ago) was a good computer. Now that I know the tinniest bit about computers I realize that it is horrible and I need a new setup. In the past year I started a new engineering firm and handed the task of computer/network setup to a computer nerd and I have been blown away with the performance of the computers that he has built for us. I have asked him to spec out a computer for my home needs and the list below is what we have put together. A little bit about me so you know what I am looking for. I am not a gamer. I do work in AutoCAD. I want two screens. I do not need it on my computer but I want 5.1 or better sound. I have to have a backup system (right now I am using a Western Digital My Book 500GB Premium at home). I want speed and more speed for surfing the net, working in AutoCAD, and running many applications at the same time on multiple screens. Ok, so here is what I am about to buy. I am set on the processor (QX6700) but I am clueless on the mother board. Do you see anything that may not work together, or may work better with something else, or that needs to be changed?

Processor:
QX6700 Intel Core 2 Quad Core 2 Extreme Processor

Mother board:
I like ASUS, but which one?
ASUS Striker Extreme (Is this just for gamers or is it the best for me too?)
ASUS P5B Premium Vista Edition
ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i (leaning this way)
Or one of the other P5N32 (Premium or Plus)

Memory: Need help here too…should I get more GB or performance? Do I need it?
4 GBs (2 orders of)
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Model TWIN2X2048-6400C4

Case:
Antec LifeStyle SONATA II Piano Black Steel ATX Mid Tower Computer Case 450Watt SmartPower 2.0 ATX 12V V2.0
This is what we use at work and I like the fact that I can lock the front because I have a few kids crawling around.

Hard Drive:
(2) Western Digital WD2500KS Caviar SE16 250GB 16MB SATA2

Mass Storage:
Western Digital WD5000KS 500GB 7200RPM SATA2 16MB

Video Card:
eVGA 256-P2-N636-AR GeForce 7950GT 256MB 256-bit GDDR3 PCI Express x16 HDCP

DVD Burner:
LITE-ON Black 20X Double Layer DVD+/-RW Burner with LightScribe

Card Reader:
Atech PRO-28U 28-in-1 Internal Card Reader Black

That’s about it for the case; the rest is just Keyboard, mouse, battery backup, and speakers.

So…what do you think?
