3 x GTX 680 4GBs cards, considering moving to 2 x Titans?
on Jun 13, 2013 at 8:05:04 pm

I know everybody asks about GPU performance, and from what I can see on this forum a Titan equals almost 1.5 GTX 680s. I am currently running a custom rig with 3 GTX 680 4GB cards with a 10% factory overclock on each. 1 is GUI and 2 GPUs in Resolve. System runs great and no problems. However the heat level and noise level could be better. I'm considering switching to 2 Titans, 1 GUI and 1 GPU. Am I going to see a performance hit? Especially being that I will be going from 2 dedicated GPUs to 1 GPU? The bulk of my work is 4K RED right off the R3Ds, so without a Rocket card GPUs aren't a huge help...but I still don't want to sacrifice any performance for the rest of my work which is usually 1080P ProRes and DSLR stuff. By moving to 2 Titans it will also free up a slot to eventually add a Fusion IO card to the mix for 1200MBs+ transfer rates. Thoughts?
