The limits depend on the card, luck of the draw.one of mine is stable past 1000 core the other not even close.True the lower your temps the better your overclock but only to a point and even then it depends on where you start.A bad overclocking card will get better but it wont turn into great overclocker under water.
With good cooling you can go over 1.35v specially if you have a fullcover waterblock.Just watch your vrm temps.
My good card will get to 1030 core before heat and voltage stop me but performance keeps increases until then.Try 1005 core with a little more voltage but keep your memory low.When my core is the problem I get artifacts or driver errors but when its the memory I get a noticeable performance drop so maybe you hit the limit on your vram overclock.
What are your load temps underwater and how much did it improve verses air cooling?Edited by smoke420 - 9/16/11 at 9:01am
