Hello, I just got my new PC installed and I have 2 GTX 560 Ti 448 Core SLI with dual monitor running at 1920x1080. After viewing many discussions, I realized that the 1280MB ram come with 560 Ti 448 core would not be sufficient for dual monitor running at 1920x1080. If I only play games on one monitor and leave other things on the other, will my two cards capable to handle everything smoothly? Should I reduce resolution? Thanks
