Hi I currently have a radeon HD 7950 in my set up and plan on getting a second one.

My case is a 600t and I want to get 4 quiet fans to add to the sude panel to improve air flow, but I was wondering, if I under clocked my gpu's would I still get better graphics performance then if I just stuck with my 1 hd 7950 at stock clock?

thanks!

With a program like MSI Afterburner you can both under-clock and manually set the speed on the card's fans. You can choose to have the fans running at a lower speed without under-clocking but in that case your cards will run hotter. But that's compensated with the four new fans you're adding to you case, adding air-flow directly to your cards. I'm pretty sure you can skip the under-clocking and lower the speed on the fans slightly without any problems.

As a test-run with your cards. You can make your own "map" on how fast the fans will go when they hit a specific temperature in MSI Afterburner. I recommend you trying that.

I lack knowledge of Crossfire but I'm quite certain it depends on how much you under-clock them. But why would you want to have them going lower than stock in the first place?

Forgot to mention that, I was hoping that I could reduce the noise level of my system while still getting better performance

does MSI afterburner work with xfx cards? and if so is their anything special that I need to do to switch from Catalyst to Afterburner?

I myself have a ASUS card, working flawlessly with MSI Afterburner. And no, there is most likely nothing you need to do in Catalyst in order to support Afterburner, which is just another program as Catalyst.
