What's a good OC for a GTX 980 Ti?

GPU and VRAM.

Something around 1500MHz on the core and a +100 offset on the memory.

I don't think I'll reach 1500 MHz on the core GPU.

The stock cards only boost to 1075 MHz.

I can try though... doing a stress test using 3DMark right now.

it also depends on the model of the card, the zotac amp extreme boost to 1600 or so no problem.

Model of the card doesn't really matter - some of the higher end GPUs may overclock higher than a non-factory overclocked one, but it's all just hit and miss if you ask me.

I've got a (two, actually) Zotac GTX 980Ti AMP! Omega.
Base clocks
Core - 1178 (boost 1279)
Memory - 1755 (7020)

I can push the core on one cards I tested up 150Mhz and the memory I can actually crank on pretty high. Here's my overclocked speed that runs stable on Heaven 4.0:
Core - 1328 (boost just breaks 1500)
Memory - 2160 (8640)

Here's the most stable OC I get when actually gaming:
Core - 1313 (boost 1479)
Memory - 1950 (7800)

As for actually running an OC, I don't currently. Pushing the clocks can give me upwards of 10-15% boost in games, but generally speaking my 4670k @ 4.4 and stock GTX 980Ti cards in SLI - there's no need for overclocking the GPUs.

I've had identical cards, same BIOS with 8800 GTS 512MB - one could take about 100-150Mhz boost on the clocks and the other couldn't handle an overclock to save it's life.

I've also had 2 different model GTX 570s (even from different company - 1 from Zotac, 1 from EVGA). The Zotac card I could overclock higher than the EVGA card. Max clocks are;
Zotac - 900/2100
EVGA - 882/2050

Every card is different, even if they're the same model and use the same BIOS. Just step up the overclock a little and benchmark. If stable, up the clocks a little more and benchmark....do this over and over until you find a spot where the system will BSOD or just become unstable in the benchmark. Once you hit this spot, go back to your last good overclock and make small, minor adjustments to finally reach your max.

Once you hit your max overclock in benchmarks, run that overclock in a few games to see how things behave. You may find the overclock isn't stable in games or maybe things will work without a hitch.
