His board has triple channel support, unlike the dual channel most of us have.
And to the OP yes upgrade your video card, I purchased a 7950 w/ Boost and for the money its one of the best cards u can buy, plus if AMD are still running the promo, u get Far Cry3, Hitman Absolution, Sleeping Dogs FREE, ($170) and 20% off MOH but don't waste ur money on that. If you prefer nVidia, grab a 670.
the above link will tell you how to fix it. i did it myself and it works 100%.
it takes all of 5 mins to do and 1s done your fps will jump to 30+ as long as you dont go mad with settings above what your card can handle...
