I am looking to purchase graphic card(s) so I can use my 3 Monitors 1080p and record video for youtube. I was hoping to keep it bellow USD ~700.00, but it is okay if it is a little bit over. I did a bit of looking around and I know there are Screen Buffer issues with running SLI/Crossfire. I can provide technical information if requested. GOALS: 1. Run 3 Monitors 1080p 2. Record Video in 1080p 3. Run Heavy(er) Games. (Example: Crysis 2/3, Portal 2, etc...) I have been looking at the GPU Benchmarks and I want to know if a GTX 780 or 2 GTX 670s is better? Thanks for the help.
