Hi, I'm having a bit of trouble running Supreme Commander on the larger maps with massive amounts of units. Graphics is definitely not an issue (I'm maxed out and there's no noticeable lag at first (8800 GTS 320)). The trouble is, would upgrading my memory to 4GB from 2GB help more or less than getting a quadcore like the Q6600 or a penryn? I have a E6750 currently at stock. my motherboard is a P5N-E SLI (4 slots with support for 8GB). Thanks for replies.
Edit: I'm running on Vista 64
