I was a bit scared to start 5-boxing with my current system after reading these boards, Various posts I read seemed to point towards only mega-high-end systems being able to handle it. People reporting 10 FPS with 8800 GFX cards, etc.

For some reason, i am getting 30-fps on all my windows with my current setup
core2 duo (i think its like 2.2ghz, dual core)
7800 GEFORCE 256 MB
4gb ram
windows xp (so im only using like 3gb of that ram)

maybe its just the 2.3 dual core improvements that are letting me get these framerates?
