Gtx 560 upgrade to gtx 680 bottleneck issues and fps gain

[knifeking]

Hi guys .
I am looking into upgrading my gtx 560 (non - ti) to a gtx 680 card.
The questions i would like to ask from you guys is would a gtx 680 bottleneck my cpu?
And also what fps increase could i expect with the upgrade in games like far cry 3 ens?
I realize it will differ from game to game but a rough estimation would be great

my specs if needed:
core i5 2500k @ 4.5ghz
8gb kingston ddr3 1333 ram
msi gtx 560 twin frozer(obviously might change)
msi z68 ed55 motherboard( could be slightly mistaking)
samsung syncmaster B2330 23 inch screen

i game at a resolution of 1920 by 1080
thanks for reply

40 FPS in Far Cry 3.

55 fps according to http://www.guru3d.com/articles_pages/far_cry_3_graphics_performance_review_benchmark,6.html.

ur CPU is good enough, wont bottleneck the gtx 680. For better performance the only solution would be 690 (2 cards in 1) or SLI/Crossifire, but i wouldnt recommend it. You would also probably need a new PSU, but dont know because you didnt say what you have right now.
