My first gtx 580 is a palit 3GB.
Thanks for any responce
I agree with people saying it's bad idea to pair 1.5GB and 3GB cards. I'm thinking in best case scenario you will be throwing away perfectly good 1.5GB of ram on 1 card, in worst case - who knows what weird problems you can get because of that... I mean did anyone even attempt to do it in real life? I've never heard of it. Either save up for another 3GB card, or sell yours and get 2 matching 1.5GB.
Regarding bottleneck - short answer yes. Long answer: depends on the game. In GPU intensive games (Metro, Witcher 2 with ubersampling) your CPU should be enough, but in anything less visually demanding you will most definitely be bottlenecked.

A small bit of bottleneck, but really unnoticeable.
Sometimes it will, and your I7 will too. Here is my I7 @ 4.0Ghz severely bottlenecking my 580s in Crysis
@ 1920x1080, DX10 maxed out with 16xAA. Crysis 1 is old, but still pretty graphically intensive.
