  1. At that resolution it is definitely your CPU that is the bottleneck (you would probably get close to the same with a single card). Higher overclock would reduce it but the best thing would be getting a 1080P monitor so you can harvest the power of your SLI setup.
  2. ^+1, He is getting a little better than one, my hd6850 got 35-60 FPS, so he has a little FPS gain though.
  3. Rolli is correct i had the q8400 with two 460's before and it does bottom neck it. It does help if you can get up to 3.2 or higher.
  4. 100% right rolli
    i suggest that you either overclock (and get cooling) to squeeze out some performance or get a new cpu, your power supply permits
