Hello, I just bought a GTX 460 a little over a month ago to play the Battlefield 3 open beta coming out in two days. I recently checked the recommended specs and see that they are now recommending a GTX 560. I bought my 460 through EVGA so I can use their step up program but its probably going to cost me about $100 difference to upgrade to the 560. Is it worth the upgrade, or will the GTX 460 run the game well enough?
