Now, you're missing a Power Supply here. This
Xclio should be perfectly fine in a system such as yours, no need to spend 40 or 50 dollars more on more power that you don't need, especially with a GTS only needing one power connector anyways. Now, this WOULD put you 60 dollars overbudget. But, when you're talking about dropping a thousand dollars - that 60 dollars represents going overbudget by 6%, perfectly within boundaries of acceptability.
This system is fairly well balanced, and would run good. 800Mhz ram, CL4, should give you room to overclock the E6300 a bit. The S3 is able to provide that overclockability, at a good price. The G80, well, leave it to itself, it'll do fine. Now if you wait, buy your time - you might be able to find deals. Hell, with this deal right now you'd get Ghost Recon: Advanced Warfighter for free with the E6300. That's a 40-50 dollar game...hell, you could probably sell it right now for 20-30 bucks and make some money back. Plus, you have your old components to sell and recoup losses on. the components your girlfriend's computer is getting rid of, or else maybe she doesn't NEED that DFI lanparty board.
Just remember, do it once - do it right. You seem to like to buy something, then misthink, get rid of it, and then start over again. Gotta be patient. I make the coin that I could go ahead and go finance off of Newegg a pretty damn powerful computer right now if I wanted to. E6600, Evga 680i, GTX, etc etc. I'm patient, I wait, and I plan and plot. You also planning to attribute 80% of paychecks towards paying this off? Bad move. You don't want to overextend yourself financially. I would say no more then 50% or so of paychecks should be considered "bills", which financing a computerwould be a bill. That other 50% should be for rainy days, and just spending on the old lady.
Just trying to help you out. You probably don't want to listen, but someday you will.
