I am helping my friend put together a new gaming rig. Any suggestions on a combo for ~$750 or less? He already has GPU and RAM solutions, so no need for those. He is going to be using my old 6850 crossfire cards for now, so that's something to keep in mind. I figured to go with Ivy Bridge so he is a bit more future proof if he wants to upgrade to a PCI-E 3.0 card in the near future. Here's something I threw together real quick, figured I would ask you gurus though.
~ $540 (not counting shipping, promos, or rebates)
This build uses your same case, psu, and cooler, but with a FX flavor. Your IB build is great, but if your friend would like to save a few bucks a FX build is not a bad way to go. Look at this article: http://www.legitreviews.com/article/1914/1/
You'll see that the FX is only a few fps behind the IB. Either route is a good choice.
