Okay, I don't have the newest rig on the block, but I just played a 3v3 with 5 AI's on the Brothers map. I got up to more than a Gig of Mem usage and 95% CPU (I have an Athlon X2 2.7 Ghz, 2 gigs of RAM and an 8800 GTS). This is not supcom, there probably wasn't more than 200 units on the map at any given time, and I can handle 2v2 battles in SupCom easily (which should be more CPU intensive).
