AND BACK UP WITH INTEL !
intels were never designed for games, they say that themselves.
hewho dude, i seriously dont think it would be worth selling ur old parts, buying new parts just for a bit of gain in games. and yeah yeah amd fanbois come tell me AMDs r fine for apps, yes, the FX series and 3500+ and above.. but in this guys price range, it would not be worth it..
Long story short.
That mobo is fine, and stick with what u have at the moment, intel. You will not see a huge performance gain.
