I'm looking to upgrade and water cool my build this summer and I've been looking at forums for which 7970 has a reference PCB design so I can use a full body water block. I've heard that the Sapphire 7970 OC has the original PCB design, but wasn't sure because I could've sworn that they have changed the design.
Best reference 7970?

be very carefull when using die's in water cooling loops. they almost ALWAYS clog the system.
the dye breaks down, stain your tubing, will stain the Perspex in the reservoir and block. and a lot of the time will clog the water blocks and restrict / stop water flow.
This is not a matter of it "might happen" it WILL happen.
you are much better off using coloured tubing with just demineralized / deionised water with a couple of drops of liquid utopia.

I am not sure, most waterblock manufactures have a database of what blocks fit what cards
I have personally been using Standard HIS or Sapphire 7970s (non GHZ models) which fit the water blocks i use

pretty sure EK has a database, as i am sure i have looked up cards on their Database for my original 7970 waterblock before i sold it and changed to Heatkiller blocks

I got the heatkiller on my Sapphire 7970 also.
I think it looks ALOT better than the EK.
also I check out a few reviews of multiple waterblocks and the Heatkiller got high recommendations in all areas (temperature, flow restriction & price)

I do like the look of them, but I was wanting a water block that would be transparent to show off the liquid.
Which brand makes the best 7970? I'm looking into a Sapphire, but I've heard good things about Diamond its just hard to find their cards. I'm wanting to OC the card to about 1100mhz if I can.

as for 1100mhz, should be no problem
for benchmarking I got mine to 1260mhz/1800 Mem/1.262v and this with not a lot of effort.

Really? I thought there was some coolants that had coloring in them. If that's a problem then I'm going to have to use a different res because I was going to go with this one: http://www.ekwb.com/shop/reservoirs-and-acc/reservoirs/ek-bay-spin-reservoir-acetal-csq.html
And if you got up to 1260mhz then I'll probably try to get it around there too. I've never OC'd a GPU before so it should be fun! Haha

there are some coolants with colouring in them yes. these also have problems. Mayhem Dye's were quite bad for it. some say they are better now.
others just accept that adding dye also adds the very real and high risk of damage to the loop, from staining and clogging.
by far a safer option is run with colored tubing.
all of these systems you see with bright vibrant coloured coolant are just display systems that only need to run the coolant for a week or so. (like the one in your link for the reservoir)

I stopped using Ek water blocks on my 7970's as they changed the design of there 7970 waterblock in the middle of my build, so i couldn't easily join a 1st series block to the newer block, so i sold it and moved to Heatkillers, which look fantastic

mine is the stock standard basic 7970,3gb.
don't bother with the factory OC versions or even the GHZ edition as you will surpass that quite easily on water cooling

I have had mine a little while now (12 months old maybe). I bought it 2nd hand (3 months old with receipts) for $350.
the sapphire ones come with a 2 year warranty standard also.
