On another note, when I had a single GTX 260 and a hx520. I was told a better, bigger PSU would be a good idea. and that it would help with overclocking.. So I got one. the 750w Quad I use now.. But then I added another GTX 260. I am now wondering if I am close to the same area as I was before, and I just don't have enough solid PSU power to help with my overclocks.

The reason I say this is because after I got the better PSU, but before I got the second 260. I was able to boot at speeds of 4.275 Ghz, and be stable enough for some Benchies, and I loaded at 4.3 Ghz but wasn't stable.. I tried last night to OC my CPU, and I went to vcore's that I've not done in the past, thinking I'd go over my 4.3 Ghz personal best.. and I could not even load at 4.3 Ghz.. Not even with 1.42v and I did it with less before. So this makes me wonder if it's PSU related now that I'm running SLI, (Oh and Water cooling) So I'm now running SLI, and Water on the same PSU..

Maybe I'm wrong. I don't know. Just thought I'd post and see what you guys say.. Maybe I should just get a 1000w PSU.
What are your max clocks on a the hx520? Because Im running into some PSU issues as well (at least I think). Anything over 4ghz is just unstable. But I want to make sure its the PSU before I buy something else.

Running a Zalman ZM-600HP with 4*16A rails and a GTX285. Prime/Memtest/Linx stable, yet Crysis/3dmark06 = instant crash.
