Hi, Tys. :)
Did you see the link I provided a couple of posts ago? If not, here (
http://configure.us.dell.com/dellstore/config.aspx?cs=19&dgvcode=ss&c=US&l=EN&vw=list&oc=DDDADG4&dgc=CJ&cid=7420&lid=0) it is again. It's a Dell, I know, but I've had the same Dell for six years and the only things that went wrong with it was the monitor (a CRT, and I needed to get an LCD anyway) and the optical drives, which were cheap as hell to replace.
Anyway, here's what this Dell has:
-Q6600. I checked all of your links and none repeat: none of those systems have anywhere near that kind of processing power. Well, that 2.2GHZ Phenom from Costco comes close, but the Q6600 still blows it away. If you wanted, I could show you how to make that Q6600 run at 3GHZ for the cost of a rear-window defroster repair kit and some Arctic Silver 5 (<$20). I think that Kmart computer has a Pentium 4. They stopped making those, like, 2 years ago. :xp: No joke.
-3GB RAM. Basically all that Vista 32 can utilize.
-Vista Home Premium. Some of the systems you linked to come with XP (no DX10), and some don't even come with an OS. There's $100 bucks right there.
-500GB hard drive.
-No crappy video card for you to have to sell. Just buy whichever one you want. With Nvidia and ATI locked in a price war, there couldn't be a better time to buy a video card. You may or may not need a better power supply, but there are deals for those all of the time and we'll help you find one if you need it. You may not need one. Dell PSUs are pretty beefy, because Dell doesn't want to have to replace them while the machine is still under warranty.
-DVDRW drive, keyboard and mouse. All you need is a monitor, speakers, and the afore-mentioned video card and you're ready to game.
It's $499 right now. It's the best deal that I could find ATM. Trust me. Buy it.
*Alienware is highly overrated, and overpriced. ;)
