I`m guessing it`ill run okay at the lower settings.
And your guru is right, too many get all tangled up in MB when it comes to graphics cards. A Geforce 5200 wouldnt run the game if you put 1GB ram in it. The gpu (brain) and other components are of equal if not greater importance. (Of course, a 8800 with 5MB memory wouldnt run it either, but you get my drift)
What I have been told (and read) is that the only performance difference - or close to - between say a 7950GT 256MB and a 7950GT 512MB is to be seen when resolutions are high. (Above 1280x1024)
