You don't say what OS you have... 2000? Xp? Vista?
I usually use nVidia drivers, but, sometimes, you better off using video card maker's drivers.
The other thing is that you did two extremes. You used the newest driver, one extreme, which is probably optimized toward 9xx and 10xx series cards. And you used an original driver that came on CD, this is safe option, but you know there were newer/better drivers that came afterward. You could go to the driver page (nVidia and/or card manufacturer), look through driver release notes and see at what point they started to include 7xx and 9xx cards in the driver, that is the point where they started to move away from 7xx cards toward the next generation (9xx) cards. Pick that driver or one before since it will have the last 7xx support.
Another thing to keep in mind is that low end 7xx cards (710, 720, 730) were often rebadged 6xx cards. For example, I think, EVGA did that. You would pull spec on 610 and 710, and they would be identical. So run GPU-z on your 710 and see what are the specs on your card.
For the record, I went from GTX 460 to GTX 750Ti SC and 750 is what I have been using for the last few years.
