Does overclocking the GPU speed up the render time noticeably?

It's about the cooling system: I want to purchase two Titan RTX GPUs and I need to know if I can leave the base clock at standard 1350 MHz, and also the standard heat sink of Nvidia as it is. Or overclock it to 1770 MHz and install a water cooler system for them. So does anyone know if there would be a big difference between rendering with two Titan RTX with 1350 MHz or 1770 MHz?

It would make some difference but not enough, IMO, to justify the expense of buying the waterblocks, pump, resevoir, radiator, fittings and tubing plus the increased chance of hardware failure and increased system maintenance involved. But if you're spending $5k on cards and really want every last bit of performance feel free.
Actually it's 2700 € per card where I'm living, so it would be around 6k Dollar! Anyway, I just would like to know how much % it would be faster. If it's just 2-3% then it's not worth the overclocking. But if over 15%, then it becomes more interesting. And what about the cuda cores? The Titan RTX has slightly more than the 2080 Ti. Wouldn't it be just out of this fact faster leaving the MHz out?
The Titan RTX will certainly be faster than a 2080ti. As to the overclock, You can dig through the benchmark thread and compare cards that have a factory OC to those that don't. It was my impression when I looked over that thread a while back that the factory OC's made very little difference.
