That way you get a really good Idea where your card is stable vs where you start actually LOSING performance because of an unstable overclock. Maybe see what it takes to be stable at 825-850 and go from there? Hope I was able to help at least a bit. Post some results!!
Was able to get 850MHz core 1300MHz memory at stock voltage earlier with no issues whatsoever. At ~865 it started to get slightly unstable. Been going up in small increments paying attention to heat and have stopped so far at 903MHz core, 1300MHz memory, and 1.162volts. (45C idle, 68-71C load in GPUTools stress test)

Performed much better in benchmarks with no errors or instability issues so far.

That is AWESOME! You seem to catch on quick. Now the question is, forgetting about benchmarks for a minute, has the overclock provided you with a more enjoyable experience in games? Have you been able to distinguish a genuine difference in the playability of your games at the same settings?! I'm very excited for you! LoL,

have you tried overclocking core clock only?
you should get mor performance out of higher core, and higher memory clock just seems to stop being important after a point
first oc your core without ocing memory
then see whats the max you can get stable
and then go after the memory with your core at stock values
after all that, combine your core and memory clock for best results

I had done exactly just that before i settled on 903/1300. Individually at 1.162v i was able to hit 925 core and then 1385 memory stable. However, when combined and stress tested my pc locked up immediately and blue screened on me. So to be safe i lowered everything quite a bit. Raising voltage to 1.2 also seemed to give me minor issues, 1.162v kept my temps pretty good at 72C max under stress tests and was completely stable.
I probably could have pulled more out of the card, but I'm content so far with the results.
In your opinion should i try raising voltage again?
What are some other signs I should look out for that indicate instability in my card clocks?
Also, is running the fan at 60-70% when the Afterburner OC is enabled a risk?
Or is it more so just a noise issue.

I'm excited as well I need to get my hands on a game that actually puts the card to the test so i can see if it made any real difference outside of benchmarks, any suggestions?

All depends on what you enjoy playing! I personally like to get down on some L4D2, Crysis 2, Portal 2. Batman: Arkham Asylum is a really really pretty game with nice gameplay as well. All of the AC series....etc. But that's me, I'm not really big into RTS or MMO's but to each their own!

Not into RTS or MMO's as well, might pick up crysis 2 or arkham. I've read that there is a way to actually mod my BIOS and unlock all the features i would need to oc my cpu that gateway locked up. Is that true? I searched, but was unable to find anything.

metro 2033 also is one of the most demanding games
but if you want to see results just check out games you allready have overclocked and not overclocked
there might be a way, but i think that would be a serious pain in the ass to make it work, so i'd definitely give up on that - wouldn't be worth my nerves

I'm sure you're right, just going to start saving now for a new system and continue to learn and read as much as i can in the meantime. The most i might do is upgrade my card if i see that I'm not running BF3 as smooth as i would like.

What program to further test stability do you suggest? And how long should i run it for? Hour, two hours, over night?

well everyone says differently about what they think is stable and there is a million answers

i don't know whith which program you tested stability untill now

i like atitool, 15-30 minutes in that is good i believe
gpu's don't need to (and shouldn't) be stress tested like cpu's for hours
