You really need at least a GTX 660 to run stuff at 1920 x 1080...
The 650ti is kinda wimpy - but okay if you're not a gamer playing first-person shooters ie. putting 1000 hours into Skyrim etc.
Yes I too am nVidia only!
I'm gonna get meself a 660 (GTX 660ti is still too much coin).
That's not true at all. Before I got my hd 7850, I was using a GTX 550 Ti and playing everything at 1080p with most games running fairly close to maxed out, if not totally maxed out.
