I think you're overstating that just slightly with "terrible" and "absolutely destroys". Yes the 7770 is faster on average than a non-OC GTX650, but by maybe 10-15% at best. So enough to turn 30fps into 33-34fps. Not sure that constitutes absolute destruction. Anyway, what company is behind the GTX650 you found? I avoid Sapphire after a history of bad experiences with them. I've owned three and all three died on me. But I was maybe just unlucky with them.
