Answer #1
560 gtx ofcourse
Answer #2
Yes, 560GTX is the best out of those..
Answer #3
560 GTX twin frozar indeed. Out of those cards the 560 is the most recent card, although you have to be careful about buying used cards. Did the person who used it OC’d/stressed the card a lot? Also 100$ cards aren’t made for gaming, if that’s your plan.
Answer #4
560 is a great card, I had the Ti version. Played everything at max settings back in the day.
