Just finished building my rig, only question is would a quad core intel i7 2600k (3.40Ghz) bottleneck a 3gb nvidia gefore gtx 590?
No. All those parts are pretty much on the same level. It's not like you're trying run a 590 on a single core 1.5 Ghz CPU. There you would have bottle necking for that setup though it should be ok.
