the pci 3.0 won't have any effect on what you do. If you want an i5 the get it bro. The 3579 ($219) and fx-8350 ($199) at newegg...cheaper on amazon. Similar in price. Only 20 bucks separate the two. Remember though fx is upgradeable witha new mobo...3570 wont be upgradable to haswell without new mobo.
^ Dude got a point AM3+ socket is going to live more and 1155 socket is dying in 2 weeks, though AMD has not released anything official yet for the upcoming cpu's this year, only rumours are on the air, your call really.
