(Low Price but powerful is my intention these all price out to around $750-ish, I didnt list the price of the monitor, keyboard, and mouse)

My goal is to build a Gaming PC, I'm not looking for a monster, just something that can play most games (FPS, MMOs, etc) lag free, and close to max settings at least.

Might be easier if you just list the names of the parts or give the direct links to the parts =)

done. i was sorta in a rush in posting XD. I took a look at the setup above and I think I need a network card ...whats about average price for a 'good' card?

For network? You mean like a wireless card?

Those can be had for about $40-50

As for suggestions, I recommend another motherboard, the one you choose does not have heatsinks for the mosfets and that is a recipe for overheating if you overclock.

Good choices on the ram and cpu, burner looks good.

I recommend switching the harddrive to a western digital black, only a few bucks more than the blue but much better performance.

The PSU, I recommend going with Corsair or Antec brand. The PSU is a key component and you want a quality one.

If you dont mind the looks try the Antec 902, better cable managment and dust filters on the fans.

Since the computer is for gaming, if you can afford it I would get the geforce 260 core 216 for around $150 or under, much better performance than the 9800 you listed.
