I tested with 6 clients, all running 800x600 except the main. The main was at 1680x1050. None of the clients got above 900MB,
and I didn't seem to have any noticeable slowdown on my main. Granted, I was not actually playing the other 5 accounts, but they were running, rendering, and eating ram. I did not peak out my physical RAM, so there is hope that 6GB is enough.

I'd says there is a fairly good chance your 8GB will work well in most cases.
