I was wondering if a 660 Ti would max out games at 1080p with good frame rates. I may be willing to get a 670 but will a see a big jump in performance? I will play games like Skyrim, BF3 and maybe Guild Wars 2. The Cpu is an I5 3570k. Ram is 16gb 1600. Also I would like only Nvidia for gpu if you have any other suggestions. Thanks.
