I'm about to get three 27" monitors, and wanted to know if my setup could effectively run current games in eyefinity mode; i know that is one gigantic resolution. I've been out of the community a while so I figured it would just be faster to ask for help.

Was thinking of going up to 16GB of RAM or getting another card for Crossfire if need be, but would rather not if I don't need to.

What say you?
 
Eyefinity will not run smoothly on mid to high settings with a single Radeon HD 7850.

Also I would worry about the CPU, this could be a bottleneck for 3 monitor gaming, too.
