Best GTX 670 OC'er for WC

Ok guys I know it varies from card to card and it's purely down to the cards you get. But looking at the benchmark threads I've seen the GTX 670 Windforce cards up there more than any others. Due to the nature of the overclocking in the 600s, is this because of the bigger/better cooler or because they are genuinely the better OC'er?

I'm looking at getting a GTX 670 4GB and maybe a 2nd one depending on funds, and putting them in my water cooling loop. (replacing my old GTX 460 2GB SLI)

Basically I was wondering if any are renowned for being better overclockers, or if it's just the fact of the cooling? If they are all pretty similar then I will probably go for the cheapest. What's everyone's experience with these cards?
 
Go for the reference one I say, although since you're water cooling have you not thought about the 7950? You'd be able to pump somevolts through it and clock it nicely!
 
Ok, reference being the shorter PCB? I haven't looked too it too much yet. Out of the 4gb version on Overclockers, there the EVGA superclocked, Asus and KFA2. The EVGA is the only one which doesn't state full length PCB, so I guess the EVGA is reference?

Also is there a benefit over the reference and non-reference? (Asus and KFA2 state better overclockability). But obviously better block compability (although had no trouble getting blocks for my non-ref's), and they are shorter I suppose.

*EDIT*

Regards to ATI, I have seen how good this generation performs, but just never really considered getting one. Atm I've got 3D vision, but I'm going to get rid of this soon. I've always had Nvidia so am familiar with how everything works. So the 7950 is better overclocker than the 670? (Also, is the 7970 just 2x 7950?). Also how is the compatibility/performance of crossfire compared to SLI?

No the 7970 is not 2x 7950's
Its just a faster single GPU than the 7950.
Crossfire Scaling is VERY good, just look at the Vally benchmark, its close to 95% scaling in there.

A 3GB 7950 Overclocked would do wonders.

Yeah, the Evga 4GB superclocked is of reference 670 size.

I'm just hoping that the 670 blocks remain around for the next couple months for when I aim to dip my toes into water cooling.

Hmmm, I've spent the last week debating over 2gb vs 4gb, then 680s vs 670s and checking out the 690s and the titan, lol. Now my decision has just got harder.

I think I'm limited on length though, as I saw 1 7950 which was 11.8 inches long, atm I've got a cylinder reservoir to the right of my motherboard. Although it's possible to buy shorter tubes for less than £15 so maybe I'll be alright, I'll have to get the case open and measure everything.

670 FTW + 680 waterblocks.

Why do you say that? i guess 670 is the same PCB as the 680, and it overclocks better?

Also, what PSU watt would be recommended for overclocked 7950 CF, atm I've got a Corsair TX650W. Would this be enough? Atm running an 2500k (not overclocked atm) and 8gb ram.

If upgrading to x79 and like an 3797k would it also be enough?
 
Correct, the FTW and Gigabyte windforce 670's use the reference GTX680 PCB, I would say your chances of hitting a high clock are slightly increased using one of the above. The FTW is 95% 680, same PCB, same cooler, same vrm layout...

Dual OC'd 7950's + X79, I'd say you should be looking in the range of 850w+, if you're benching you'd be pushing it with 750w imo.

if you upgrade to x79 and have crossfire then a 850w psu is best
 
hmm ok, I'm just thinking if I'm upgrading the PSU I might as well just upgrade the mobo and cpu, maybe get a 3820 as the 3930 is abit expensive. Then I've got 2nd pc too (GF's brother is thinking of PC gaming and ditching the PS3/4)

IIRC the 670 FTW is a binned chip so the you should be able to crank up the speeds a bit more. As mentioned above, the 670 FTW uses a reference 680 PCB so it fits 680 waterblocks.

If the GPU length is a problem then you could look into a 5.25 Bay reservoir?
