yea, the whole ti/no-ti thing is really confusing. Especially since most people mean the 560Ti when they say 560. Also, it doesn't help that whenever I try to find reviews on the 560 I only ever get reviews for the 560Ti and they call it a 560.
I got the 1Gb version since I can only run up to 1080p if I plugged it into my HDTV. Currently I'm on a 1680x1050 monitor.
