I am thinking of upgrading to a 660 but I am worried that it will be bottlenecked by my Intel Core i3 2100 whilst playing Battlefield 3 multiplayer. I will be playing BF3 at a resolution of 1920x1080 and I will probably be playing at high or medium settings depending on whether I can get 45+fps with the 660 while playing on 32, 48 or 64 player servers. So will a bottleneck occur when playing BF3?
Your help is appreciated.

Its more like your CPU isn't up to par to handle BF3 on the larger maps like 64 player ones. I'd just avoid the larger maps and you should be fine.
Also BF3 min requirments is dual core.
You cpu won't be able to handle BF3 multiplayer. I would upgrade it as soon as possible.
