You should go up to at least Extreme4.
Sub-100 boards tend to flex a lot, be horrible at OC/Stability. And die quickly
I bought the Pro 3 earlier this year for a i5-2500K build and I couldn't be happier with it. Got it for a steal ($30) from Microcenter with the i5 combo package.
It's my 2nd build and I really knew nothing about the MB before buying it, but it's turned out to be a pretty decent investment. I know a lot of people recommend the Extreme 4 instead and I won't disagree really but if you need to cut corners somewhere I would think the step-down to the Pro3 is a decent place to do it.
