I too highly suggest waiting for at least reviews of the GTX660ti which may well be the best option for you, but my gut tells me (not knowing any specifics about your specific PSU) that you should be fine with a 670, especially if you're not overclocking (*much*).
It is the best option for a person in your position, assuming you're gaming @ 1080p or less.

Given your disinterest in overclocking and desire to use for multiple years, then the GTX670 is the only choice, and from what I can find out about your PSU, you should be gravy mate.Get the 670 and call it a day.
*I say the 670 is the only choice because AMD cards have massive overclocking headroom and their best performance and value for money comes through easy and safe overclocking. The 7950 has been known to overclock by up to 50% on the core and 30% on the memory, which turns it into an entirely different beast. It simply cannot be stated to be an irrelevant difference - overclocking here is essential, and not doing so is absurd and frankly, stupid. Really the same can be said about any component. At the very least, one should find the max stable overclock at stock volts and run that without a shred of danger or concern, maximizing efficiency per watt for the consumer. Anyway and back on topic, the 670 will give you likely the best gaming experience for the longest out of the cards available, in the most efficient way, and without overclocking required. It's your best choice.

And you're on the wrong forums with that attitude towards overclocking mate hahaha (joke)
Seriously though, the only way you can "kill" any of your components through overclocking is by increasing the voltage (or potentially running them unstable constantly crashing). The "dots" you saw on your last GPU overclock was because you had reached a limit on either the core or the RAM that required more volts. All you had to do was back the OC off slightly, run a test/game again and see if it works. If it did - the overclock was done. Extra performance for FREE with no added voltage so ZERO chance of killing anything.
Actually, your components are sold running at volts way below safe ranges, and your CPU and whatever new GPU you get can both be run with small voltage increased overclocks, with standard cooling, at ZERO danger increase.
I do suggest looking into how the process of overclocking is done itself. Once you understand it, then you can safely mess with some settings and get some free performance. All you have to remember is that you should take your time, make small changes in a logical manner, and if one change makes your computer unstable whilst testing, then simply change that one detail back and re-strategize. Simple. Safe .Fun. Free performance. As you get more confident, you increase the volts slightly (and increase your cooling setup) and you get LOTS of free performance, whilst staying in safe temperature and voltage ranges, and are thus perfectly safe and can expect your PC lifespan to decrease by a minimal amount at most (we are talking CPU's lasting 8 years instead of 10 or 12).
There's overclocking like I do it, and there's OVER-F@%KING-CLOCKING like the professionals do. I've NEVER killed any components.
And the 670 will be equally better whilst running FRAPS.Seriously - the 670 is the card for you.
