Everything seems great and yes Elbatrop I will be the one person for now.
Understand that the 8600GT is a good bit weaker than the 7900GS in DX9. Dx10 isn't mainstream yet and won't be for at least another 5 months. The 7900GS is already a mid-range card that can't handle the newest games with ease. You guys can say all you want how DX10 will revolutionize and the 8600GT will somehow become amazing in DX10 becuase it blows in DX9 for the money however....by the time it will become mainstream you are going to want an upgrade on the card anyway as I will guarantee you that the 8600GT will not go very far in DX10. Why pay more for a card that is weaker right now? This is is now and we aren't in Dx10 yet. No one knowns their performance so you can't speculate anything just yet except that there is no way a 170 buck card will do anything better than medium setting on the newest game 6 months in the making...it just about never happens.
Stick with a 7900GS and OC it and once DX10 comes THEN upgrade to whats the best bang for your buck then.
That's just IMO.
Metalowns the Arctic Freezer pro 7 is a ripoff on newegg. I bought mine when they were 29.99 on there but now they are overpriced. Get one off of SVC.com for I believe 24.99. However if you already planned on spending 60 bucks then get a Gemini II off of SVC if you have case room otherwise a Tuniq Tower.
The TP Trio is a good PSU however I prefer this Xclio as it has another rail.

Xclio are made by the same people that make Antec so they are the same quality pretty much.
