First, thanks for all of the advice. Thanks also for all of the offers to help me build a PC, but I don't think it would be ethical, and besides, I like putting together computers.

I spent some time over the weekend trying to mock up a desktop that would let me use at least some of my current bits and pieces.

I'm not exactly thrilled with all of the components in the system, but staying at about $1,000, this seems to be the best I could do.

I leaned heavily, very heavily, on Ars Technica's Hot Rod specs for this system. (thanks, Dan) I also tried building systems with Alienware, Falcon Northwest, Voodoo PC and Hypersonic. I found that Alienware was the most reasonably priced (they came in at $2,120), but I wasn't happy with some of their options, including graphics card, so I think I'll build my own.

I think I'm going to go with an Abit KN8 Ultra motherboard. It isn't SLI-capable, but I don't think I will be using that anytime soon, and it's super affordable, coming in at under $90.

For the processor I decided to go with AMD's Athlon 64 X2 4600+. I'm still going back and forth on the processor speed. The 4200 runs $350, while the 4600 comes in at $530. I'm not sure if it's worth the extra money. I'm a little worried about the whole AMD over Intel. I know I probably shouldn't be, but I was one of those people who bought an AMD chip right when they were getting started and it wasn't a pleasant experience.

As you guys almost all suggested, I'll be going with two 1GB sticks of ram. I'm leaning toward the Kingston PC3200s (about $88 each), but if you have a better suggestion I'm all ears.

My graphics card selection was between Radeon's X1800XT or X1900 XT (both with 512) or Nvidia's GeForce 7900GT. The Radeons were considerably less expensive and since I opted for a non-SLI card, I think I'll go with either the 1800 or 1900. There's a $90 price difference between the two, so I'm still pondering which to choose.

I'm going to stick with my two Barracuda 7200 120GB harddrives. I'm also going to keep my SoundBlaster sound card and my three flat panel monitors.

Since my power supply is way too weak (250 watts), I'm going to go with an Antec SLK3800B case which comes with a built in 400W power supply. I'm a little worried that even 400W, won't be good future proofing, but upgrading that down the line shouldn't be a problem. My other option is to stick with my Gateway case and just buy a power supply like the 600W Coolermaster, which uns about $78.

This system rings up at about $1,000 to $1,200 (depending on my choices), which isn't that bad.

So here are my main concerns. Is it a bad idea to skip out on the SLI-enabled motherboard and go with ATI? And, do you think mixing AMD and ATI is a bad decision? Brian Crecente
