I am building a dedicated gaming desktop to replace my laptop and while i got the rest mapped out the way i want it the pat im having trouble with selecting a proper GPU. the set up i will be running will be a 3 monitor setup while i wont run the games on all three very often (maybe once and a while) but i want to be able to run 3D games on one monitor, a movie or TV show on another and be able to either run a second game monitor or system usage programs to monitor processor, GPU, and ram status on the third. the GPU i was looking at was the ASUS Nvidia GeForce GTX 680 2GB
Will 2GB be enough or will i have to find a 4gb version of it. or would the GTX 780 3GB be a better choice for the multi monitor setup?
