Re: Which one of these GPUS would be more ideal?
Yeah it's the same GPU. it's not the same PCB and cooling design though. it will not make much of a difference in performance sense they are both low end gaming cards. i have a Asus DirectCU2 cooling design on my GTX 770. that makes sense since that card draws more power and get's hotter then your chosen 650.
as BK stated you might want to get something a little better or at least a step up TI version of the 650
