I need help finding the right motherboard!

[WataPanda]

Hello, I am going to be running an i5 2500k and a gtx 580 matrix. I want to get a motherboard that supports 2 gtx 580 matrix cards and support turbo boost 2.0. Can you help me find one that isn't crazy expensive?

turbo boost 2.0 is processor dependent not motherboard. so any socket 1155 motherboard with 2 16x PCI-E slots with 8 lanes each will work.

here is the cheapest z68 with good reviews that meets your requirements.

here is a p67 with good reviews and also supports dual 580s

there are better motherboards but spending 3 times as much will get you 1-3% more performance and a few more slots. so cheap is the way to go.
