I was going to get a gtx 570 but I decided to get the 560 because I heard it had a better price to power ratio. However I'm not sure if it will able to run the latest games on high settings on a 27 inch monitor. Does anybody know how far I can take the 560 as far as monitor size and resolution goes (I will only use one monitor)?
27in at what resolution? If its 1440 (Apple LED, Dell U2711, some high-end NEC and Samsungs) then save up some more cash for dual cards. If its 1080P then the 560 would be fine given you have a decent system.
