Either i5 2500k or 3570k
I'll be getting an XSPC kit for cooling (with chipset as well)

Which will be better, I know the SB will get higher Ghz, but IB is better 'clock for clock'

Personally with watercooling, I'd go Ivy.

I've had all good experiences with my 2500k. At 4.5Ghz it hardly breaks 45c on air, under full load. Its a quick and cool processor.

With a very serious water cooling set, I would go Ivy Bridge. Although, Ivy Bridge has been known to be 20C hotter than Sandy Bridge when overclocked. Keep that in mind.

I won't be going over 5Ghz on either whether it's possible or not

Personally, I'd go with the 2500k, you'll need some GREAT water cooling as other people said here. :p 

I'm actually running a 2600k @ 4.5 GHz on a corsair a70, never breaks 60C in games and never breaks 65C in rendering. I can't possibly imagine what the 3770k would do temperature-wise at those clocks. :lol:

isn't the TJ max of IB 105C compared to the 72C of SB so the higher temps won't damage it surely, and I'm not going higher than 75C if I get IB

TJ max of SB is 98c,

You are confusing Tcase and TJmax

SB starts to throttle mid 90's. individual cores can go to mid 90's with the recommend < 80C.
From what I've read SB is easier to OC and Not as sensitive to voltage (SB - Max 1.5, recomended <1.4V).
Upto 5.0 with "Good" Air. My self, Upper 50s -> Low 60's @ 4.6 W/Zalman 9900 Max

IB is only about 10 -> 15% higher performance on a clock per clk basis.
But Most likely could hit Higher Freq with SB easier which would negate that (Just my guess).
Real Good read on OCing IB:
