About to purchase, any suggestions? + GPU question

[Souua]

About to make this purchase, does anyone have any suggestions before ordering?

And as for the GPU, I can't decide whether to go for the R9 290X, 290, or 280X... the resolution I'll be gaming at is 1680x1050

The build looks to be solid.
In general for graphics you want to put the best you can afford in so if the R9-290X fits your budget, I'd say go that way. You would get decent enough performance out of an R9-280X running a single 1680x1050 display for most gaming so it is an option if looking to save some - your choice

The only thing I would change is getting DDR3-1866MHz CAS 9 2x8Gb from either Corsair Vengeance Pro or G. Skill snipers for better performance. For the GPU, I will recommend an EVGA GTX 770 w/ ACX Cooler instead. It runs cooler (more overclocking) and less electricity.
