alright another question i have the cooler master haf case, its a mid case. 6 fans. And mine move alot of air with a fan controller. I was told when my buddy helped me build it that i have enough room to crossfire. Not really wanting to get a full case since i just bought all these fans for this case. (all 120mm) Would that be wise. I mean on ultra for bioshock infinite, tomb raider, and firefall. I've never passed 60 degrees.

Also if i crossfire should i get another 8g? Or is 8 more than enough?

It depends one what he considers enough.A single 7870 can dip into the mid 30 fps frames in bf 3 in extreme situations in ultra settings.I would recommend 2 if you want to stay above 60 fps at all times

A high end single card is typically better than lesser cards in CF/SLI, even though the lesser cards are faster.

You have to deal with

Microstutter
Frame dropping
More heat
More electricity consumed
Some games not supporting multiple GPUs

Go for 1 7970 instead.
