Hello, I am very happy with my GTX460, it is a splendid card and has served me for a while.
I OCed my card a while back and did not experience any issues until now,
I think the reason for this is that I started playing more GPU intensive games (Witcher 2, Battlefield 4, etc).
I have detected the problem and haven't been able to solve it or find anything about this matter anywhere.
I use MSI Afterburner for my OC, for some reason the OC or something else is making the drivers crash, and when they do, it resets the clocks to HALF of the OC, (which are lower than my stock clocks) therefor results in a massive fps drop.
If I go back to Afterburner and try to apply the OC again after it happens, it does not work, and the only way to reapply the OC or even go to stock clocks is to restart the PC altogether.

My stock settings: http://puu.sh/a98vX/cbe70fdd81.jpg
My card: http://www.gigabyte.com/products/product-page.aspx?pid=3638#ov

As you can see in the stock and OC caps, the clocks are seriously under the OC and stock settings, and before you ask, the temps don't go beyond 70c.
Please help me, I had this problem for a while and just recently discovered what causes it, but the lack of answers is frustrating.

Just tested the card and machine, everything looks in order.
I tested the card on another PC and I hooked my old HD4850 in my "new" machine and it seems to be in order after about an hour, its probably some program conflict, I'm just not sure what's responsible here.

@FunSurfer What voltage would you recommend? I am using a 600W power supply, what do you think would be a correct voltage to start with?

From my own experience, I had a GTX 570 that ran fine with most games on 1.013V vcore, but it crushed on Crysis 3, so I raised the vcore one step (it was around 1.025V more or less) and the game ran fine after that. Please note that higher vcore can shorten the life of the card, so if this will work set back the vcore to default if you switch to play less demanding games. Also you will need to search on the internet how good are the voltage regolators on your card and what vcore voltages they can handle.

So, I think I found the culprit:

For some REALLY odd reason, when I set it to "prefer max performance" it actually downclocks it for some reason, and when I put it on "adaptive" it comes back to normal (what the hell).
So its actually backwards (if you're wondering, this a fresh driver install, on the latest driver, same goes to Afterburner).
Another weird thing is, when I put it on adaptive, it spikes the clock back to normal, and then downclocks in to the same speeds again, it might work upclock it again if I apply some pressure, so Ill get back to you on that.
