Thats ok, i picked this guy up just to see if it'll work.
My guess is that it'll supercharge the whole system since the graphics bogs the cpu down so much. I tried to play COD online and its actually not too bad, but it isn't as smooth as it should be. Currently it only has 64MB dedicated to graphics so the 512 should help out a lot. If not, then i'll upgrade to the i7 dual core and another 4Gig memmory stick.
