Oh, ok then.
The pentium cpu that you chose, you will have a problem. But if you can get the anniversary edition, you should be good for a while (after you OC it, which it can easily reach 4Ghz+ OC'ed).
Regret? Well, possibly, depends on when you plan to upgrade your cpu. Since broadwell is the next thing up from haswell and the only motherboards that will support broadwell is the H97/Z97 motherboard. If you want to spend that extra 50 dollars on a Z97 motherboard to prepare yourself (Z97 if you plan on getting a k-series cpu or plan to SLI/CF).

This is a quick revision on the changes I would have done. Since I gotta take care of something first then I'll explain why I made those changes, unless someone who I know can understand why I made changes and explain it to you.
