Should I be getting better performance from my rig?

The games your playing recommend Quad Core Setups. Sadly the I3-550 is only a Hyperthreaded Dual Core.

Your MB has Support for an Intel® Core™ i7 series processor/Intel® Core™ i5 series processor/ Intel® Core™ i3 series processor in the LGA1156 package

CPU Upgrade is def what you need =D

and having said that.............. I don't know about the other 2 but FC3 won't be delivering very high frames to begin with.

Yeah, that's what I thought.

Figured I'd hit up the think tank here first. I'll probably just do a system overhaul, since 1156 is dated, and better processors for cheaper are on the 1155 boards.

Thanks!
