I've seen endless reviews on GPUs and they never talk about any impacts that running a 120mhz refresh rate would have on GPUs. I think under normal conditions, everyone's LCD monitor is running between 60-75mhz refresh rates so all the benchmark numbers are based off of that. I wish they'd start adding benchmark numbers at 120mhz refresh rate cause it's like night and day compared to 60mhz refresh rate and hopefully catching on.

So I'm wondering if any of you guys have some insight for my particular setup (which I wouldn't doubt would be the case for some others as well). Basically I'm thinking if I add another GTX 580 to my setup and run SLI I'll see a great increase in FPS and smoothness overall. I'm hoping I'll see a huge jump and not just a slight bump, anyone else have this odd dilema?

System info is in my sig.
