This sounds like myself. I want it all!!!
I'm going for MM, but I also want badges and stuff... and I want to help out the team for rank... and I want credits...and cookies are good
This is just my thoughts....If you want max credits from your current video cards (as zombie stated), keep them on PG for now. It will eventually get you the higher end MMs. Use your CPUs to get the lower end MMs. In your future rigs, get yourself some ATI/AMD cards to get more MMs in other projects. All credits acquired help the team! I hope the MM guys dont hate me for saying this.
