I am looking to upgrade my current system to be able to run three 1440p 27 inch monitors. I currently am leaning towards using the quix q2710. My motherboard will deffinly allow for 2 graphics cards, and my 3.4ghz i7 processed will not bottleneck(I can always overclock). I currently have a amd Radeon HD 7970. My current plan was to add a second, but through looking at diffrenet forums, I saw people say that was not enough. Is this true? Instead, should I sell my current 7970, and by a r290x? Is that enough? Any help would really be appreciated.
