Hello

About to buy a gpu but some last min questions. This gpu is for my Dell XPS 420 with a q6600 oced to 2.9ghz. I am building a new pc with a FX 8350 so will use this gpu in the new build later.

Which one of these is the better choice? :
GTX 560 for 80 dollars (if still at the store, used card)
GTX 560 Ti 1gb twin frozen for 159 dollars
GTx 560Ti 2gb twin frozen for 179 dollars
Asus GTX 650 Ti OC 2gb for 149 dollars
ASUS GTX 650 1gb for 139 dollars
MSI GTX 650 1gb for 129 dollars
Gigabyte GTX 650 2gb for 149 dollars

Which one of these will be best? I plan to play games and do 3D design and rendering and video editing,

Are the 560 ti's better than the 650 ti's? Does the newer 600 series chips make a big difference in gaming or 3D design and rendering?

Later I will upgrade to a 1920x1080p monitor.

650's are cooler, use less power, but the 560 ti would be a bit faster, albeit that it will require more power, if power consumption isn't of concern, go with the 560 ti the 2gb will be better for your monitor upgrade.

Well just looked at Lightwaves and Maya's websites and it looks as if Lightwave recommends the 680, 570 and Maya recommends the 560 and 660, crazy.
