There are several bottlenecks in a computer, and the graphics card is only one of them. Ram and the main CPU (and by extension, your motherboard) are the other main bottlenecks.
For ~$800, you can buy pretty good computer components to build your own computer. Here's a few guidelines:
CPU: i5 2500 (if you want overclocking, get the 2500k)
Motherboard: a Z68 mobo from a good company. I like Asus
RAM: 8 gigs from a good company, like OCZ, Corsair
Graphics: Nvidia GTX 560 is decent. Not too high end, but the Ti version is slightly better. Not too sure what the ATI equivalent is, though.
PSU: You need a good power supply. At least 550 Watts, from a good company, like OCZ, Athena, Corsair. Don't skimp on this.
HD: A solid-state drive is optional, but you do need a hard drive that is SATA compatible (3Gb/sec is standard, I think. 6 is a step up)
Case: Any will do, as long as it matches your mobo. A mini-atx motherboard can fit in almost any size case (at the expense of extra slots), but a full atx mobo needs at least a midsize or maybe full size case.
Mouse and Keyboard: Need to be USB, as most mobos don't have the round jacks on back anymore.
Moniter: Almost everyone seems to have one these days. Make sure it has an input that matches the output of the graphics card. Some cards include adapters though. Look for DVI or HDMI
