I recently bought and setup a build, but I had to buy Vista, which was $109. Without that, you could get a better video card.
But, for $1k, you should get a Quad Core. I chose an AMD, but you may like the Intel. The AMD can be had for cheaper this week than what I bought it for too. The AMD 9950 Quad outperforms the Dual Cores of both brands as and falls just under the performance of the High-End Intel Quads. That is, at least, what I have read in quite a few different reviews showing benchmark and testing reports. For me, it has worked better than anything I have used before. I have an Intel Core 2 Duo E6850 3.0Ghz here at the office, and my home computer is faster and smoother than this one at the office.
Here are the specs of mine:
Ultra Aluminus Tower
(2) 120mm Case Fans
(1) Expansion Slot Fan
Power Up 800W PSU
AMD Phenom X4 9950 2.6Ghz Agena Processor (came with free 2GB thumbdrive)
OCZ XTC 4096MB PC8000 (2x2GB)
Corsair Dominator RAM Fan
MSI K9A2 Platinum Mobo
Seagate Barracuda 7200.11 500GB SATA-300 32MB, 7200rpm
Thermaltake Hard Drive Cooler
Samsung DVDRW SATA drive
Sapphire 4850 1GB PCIe 2.0 Video Card
I got this all for a total of $1234.87
Only thing I would suggest is getting a different Power Supply, perhaps an Antec or Corsair. The processor I got was $249, and Windows was $109 You don't need windows, and you can get the processor this week for $176. So, that comes to a total of $1050. If you wanted to bump up to $1100, you could downgrade to a 512MB version and get 2, ending at about $1k, or upgrade to a single 4870 card and get just about at $1150.
