All the items are off Newegg. i have been doing lots of reading and i think this should be a decent build. biggest concern is the motherboard being to much? i may try SLI in the future, but not triple or higher.
basically +1 for Shadow and if your not over clocking stick with that cooler you got and if not get the XIGMATEK S1283 (+ the bolt in kit)
and although i used to prefer amd i go with however gives me the best bang for buck and i suggest the e7200 and over clocking it to at least 3.2 and that way its fast and uses way less energy than your current cpu choice(45nm)
Yes, that motherboard works with a 260, but I'd also advise you to reconsider the HD 4870. It outperforms it and it's cheaper. If you stay with the 260, though, you won't be able to SLI with that motherboard. About the normal vs deluxe, the deluxe has more features which are generally agreed to be worht the extra premium.
