Looking for some help

At what resolution?

Take a look at the benchmarks here:

The GTX 560 and 570 should give similar performance. If you game at 1080P I don't see high out of the question especially in SLI.

Just remember - this game is somewhat buggy (and somewhat badly coded) - and has one of the most advanced gaming engines to date.

Not Sure

Sounds good thanks for your help

Also keep in mind - playing online multiplayer will give a different experience than playing the single player campaign.

When you play online multiplayer - depending on how many players there are this will cause slow downs in your system with people joining games and leaving, especially if there are more than say 15-20 platyers.
