For gaming an i5-3570k + GTX 660Ti would be a much better choice than an i7-3770 + GTX 650Ti... A 650Ti won't be able to handle a multi-monitor setup very well... I never understood why people would go for multi-monitor, I would personally much rather have a single 27" 1440p monitor..
If you are not worried about overclocking the CPU, you could go with this. The 7970 can handle dual monitors with ease. I don't recommend dual monitors for first person shooters (or the like) because you crosshairs will be in the middle where the monitors meet. It will not be visible. Plus, I don't know your location but I would recommend using various distributors because you can save some money. If you're stuck with newegg, then here you go. This build is if you would like to CrossFire later.
