After a getting a ton of advice from this forum I'm finally ready to order all my parts! I'll probably order in the next 5- 6 hours but i wanted to post my final build and maybe get some last minute advice on cutting the price just a little bit or help finding some deals.
Notes: I'm not interested in SLI/Crossfire. Parts I'm most unsure about: the wireless card, the optical drive, GPU, monitor. This is supposed to be a $600 build + $130 - $180 for a new monitor.
Some manufacturers have the radeon 6850 for <180$. I think it's a step up from the GTX460 768MB, and even benchmarks above the gtx460 1gb version in a variety of instances. Your MOBO and CPU are compatible. Good luck.
I ended up going with the gtx 460. $130 (after rebate) seems like a great price for a card that performs that well. it also settled my irrational fears about ATI cards not being as reliable as nvidia.
Wish me luck on the build! gimme a week to get all my parts and i'll probably be back posting all my questions as i try to figure out how to build a computer for the first time with very little technical knowledge
