Hello, right i need some insight in upgrading my card.....currently have a EVGA GTX550ti 2Gb, now before everyone starts arguing Nividia vs AMD, i am going for Nividia cards.....currently looking at the GTX670, GTX680 and the GTX770 if i feel i can stretch to it, i currently use my pc for occasional gaming (only single player atm, plus ones i can mod), but use it for 3D work, UDK etc, so i was thinking maybe the power and extra cuda cores on the 680 and 770 may be beneficial, currently hooked up to 37inch plasma @ 720p native (i.e desktop etc, and Sims 3) 1080p on other games, so what one may be best for my needs, btw will also be getting next gen games, GTA5, Watchdogs etc! BTW im in the UK, so some brands not available here!
