Hi there. Few things to say. I was in your position about a month ago. I decided to go with a single 660ti, and bought a second one last week. They are both working flawlessly, and are handling battlefield on Ultra with little lag (40-50fps). Although, I will be picking up a 780ti in the next few months, for my new build. If money is an issue, go with the 660ti’s. They perform well, and don’t cost too much. I’d consider a 760 for around the same price as well (Go with the reference card). Can you let me know what games you will be playing and the other specs of your build?
Secondly, that guy who posted above me, don’t fake that you are a CPU Expert (stefenrosario). You’re going to get yourself banned, and it’s a jerk move.
