Geforce GTX 780 SLI Overclocking Question

Last response: in Overclocking
Hey guys, I recently got my new rig and decided to switch from the Radeon HD 8990 Dual GPU to two NVIDIA Geforce GTX 780 cards on an SLI setup. I'm planning on overclocking them but I'll only done this once before and it was with EVGA (which can't be downloaded right now as far as I know.) and was wondering what the best setting for this would be. Now, I know I could boot up Heaven Benchmark and just tamper with it until something crashes or I see artifacts, which I probably will end up doing but I'd just like a bit of input first. Also, my computer has advanced liquid cooling (high ass end version with a copper plated radiator and all), so I figured it wouldn't be as big of a worry with the temps.
Anyway, to any of you guys with experience OC'ing these wonderful cards, what's a good goal for my core and memory clocks, as well as the voltage? I already have an idea of what temps I need to be at.
Also, what's the best overclocking software out at the moment? As I said, EVGA is down.

I'm just REALLY cautious when it comes to overclocking as I know many have completely f'd their cards to the point of oblivion and do not want to be in the same boat as them. I know a lot of 780's come overclocked from the factory, so does that capability apply to any of the GTX 780 series or is it just a series to series thing?
I'm only asking because that's around a 160Mhz jump right off the bat and that's a bit much, but if you're positive its safe I'll go for it and if I see any benchmarking errors I'll lower it right away. Also, any recommended voltage settings?

yeah the 780 does lots of cards are factory overclocked you need a super good cooling to get high overclock you have 2 cards that probably output around 400-500w of heat which means you need probably a 360mm rad with a 120mm rad to cool them effectively or a 420mm rad and then 2x240mm rad for some really good overclocks.

Best solution
I've settled in nicely at 1180Mhz and that's more than enough of an increase for me. Thanks guys, Heaven is still running just fine and even a little better than before. I'm pulling roughly 50FPS average on Metro Last Light at 2580 x 1600 with everything maxed out except super sampling which I have on 2x.. I was getting maybe 42 before. I play on 1980 x 1200 for stability reasons but that's a pretty nice bonus, good enough for me anyway.

I'll definitely be taking a rain check on that DDR4 for at least a year or two, if I need more RAM I'll go for the cheap route of upgrading to 32GB's instead of swapping out the whole mobo. I also see ZERO need (at least for me personally) for an eight core processor of that kind of power unless you're rendering professional videos 24/7 on several monitors whilst gaming and watching youtube videos.
