A pc can easily handle MCC, even with just a normal gpu, most pc's operate on 8 gigs of ram and don't forget that most gpu's als have ram for handling graphics. Not being an elitist here, but even with 4 gigs the mcc could be easily handled.
Since if a game took more than 8 gigs of ram, the pc would crash, mostly this happens due to memory leaks in an application.
Most pc gamers also have a mid to high end pc, low ends are more commonly reserved for work enviroments.
