Hello, I am ready to update my old ring. The only thing that bothers me is witch gpu to choose. I would like from your personal experience to give me help with my final decision. My budget is around 500EUR or 650USD. As far as I can see 660ti sli beats the other two cards in benchmarks, but what about SLI problems (microshuttering, etc)? My monitor resolution is 1920x1080 and I am intrested in playing games mostly, in full graphic detail. Thanx in advance.
