Everything looks good to me.
I would get the 670 over the 680 though, the performance difference between the two is like 5% which IMO doesn't justify the price premium. You can easily just OC the 670 anyway if you wanted that extra 5%.
Also, I would not recommend EVGA unless your system is on liquid cooling; the reference cooler on their cards is kinda bad.
No I really dont need an E- ATX guess i need to switch it up because i already have the case. Think i will go with Asrock extreme4 and im going with 670 ftw dont think i should really worry about the water cooling right now until heat becomes a problem
E-ATX can fit in ATX cases in some circumstances, that being if there is enough room after the normal ATX specification on the right. Like the Corsair 600T, while being specified as MATX/ATX, can actually fit in E-ATX boards because E-ATX use the exact same screwholes as ATX. Its just if you have enough room, it can fit. I'm not sure about the 500r, and I wouldn't recommend putting an E-ATX into an ATX case without some research to if it'll fit.
The 670 PE overvolting issues were fixed, and the Gigabyte 670 Windforce 3 is voltage locked, which isn't an issue if your not going to overclock, but having control of voltage is nice. The 670 FTW from Evga uses a 680 reference cooler on a 680 PCB, so while its not as good as most mainstream non reference coolers, its certainly better than all reference coolers on the 670. The Asus DC2 is awesome as well.
ok so im going with Asus DC2, noctua NH-D14, and Asrock extreme 4 mobo, and getting rid of the bd burner and going with a sony optriac dvd drive this should outperform my gateway fx hopefully it will all get here by the weekend. Thank you all for all your input and advice
the only thing id change is the 680 to an msi 670 power edition.
keep the 16gb of ram as in a couple of years who knows games will require much more ram and ram is cheap anyways.
also keep the power supply. it may be overkill for now but in future if you ever SLI that 800 watts may come in very handy
