I'm not going flame you. But I disagree with EVERYONE saying that Microstuttering is a huge deal. It's not that big of a deal, mainly since drivers have hampered the HUGE effect (though still it exists) I think people can bear a bit of Micro-stuttering, I mean I do it's not even THAT bad.
I also think a single 560 Ti overall is a better bang for the buck. With the cheapest being $220 and the cheapest 570 being $320. True both can be OC'd but the 560 Ti runs so cool already and plus it's much quieter, that OCing it to a simple 900mhz would make it the equivalence of a 570. If OP didn't want to OC he could get this 560 Ti and be done with it, he'd still save about $85 for the same performance.http://www.newegg.com/Product/Product.aspx?Item=N82E16814125363
