I currently have a Dell ultrasharp 27" monitor at 2560 x 1440 resolution and a samsung cw226 22 inc monitor. I have them running on a single 560ti card. I raid 25 man wow and have noticed some lag in the newest content with all the pixels flying.
I am considering moving to a 660ti card for the primary monitor and using the 560 for my secondary.
Will having a dedicated card for the primary gaming monitor make a significant difference for graphics processing and framerates? Or is the processing draw from a second monitor not significant?
I am currently not overclocking the gpus, or the i7 processor.
