Gigabyte 7970 WF vs XFX 7970 GHz

post #1 of 7
Thread Starter 
Hello.

My old watercoolered Gigabyte 7970 WF had bad coil whine, so I RMA'd it and got a XFX 7970 GHz edition in retur.
Found out later that my EK waterblock did not fit to the XFX gfx cause of custome PCB card.

So I just bought a new Gigabyte 7970 WF, and put out the XFX on sale.
And recently I found out that Watercool has a waterblock that supports custome XFX PCB blocks ( Watercool HEATKILLER® GPU-X³ 79X0 "XFX Edition) http://shop.watercool.de/HEATKILLER-GPU-X-79X0-XFX-Edition/en
Mine is: XFX Radeon HD 7970 Double Dissipation 1050Mhz GHz Edition (FX-797G-TDFC) - PCB VPEAC3814PS10 only

So my question is, should I return the Gigabyte card (unused, so I get full refund), and keep the XFX card and just buy a new waterblock?
I mean, does anyone know how well any of does card overclock?
I really want to kkep the XFX since the card is black, and so is my "theme" inside the computer case, and the Gigabyte one is blue, and the EK waterblock is ugly (http://techbay.no/PICTURE/11121_1_ZEREna.JPG) .

Guess I'll stick with the XFX card.
Since if I go with the Gigabyte, I wont get any refund, and since I already broke the warrent, it wont be easy to sell.

good choice. always go with the color "theme" you like. the cooler, though, can't be seen once the gpu is installed unless you are using a test bench or something.

Keep the XFX card as you have found a waterblock specifically designed for the XFX card. moreover Gigabyte has made changes to their newer HD 7970 cards. they are custom PCB, voltage locked and not compatible with ref HD 7970 waterblocks.

Gigabyte 7970 WF : stay away from this card. even though the cooler is respectable, there is a huge chance in ending with a weak card. Some guys here weren't even managed to get more than 1100 MHz with it. Mainly because it is voltage locked..

Yes the Windforce OC extremely weak,

Before i had my Saphire hd7970 i ordered a windforce, even with the GHZ bios and 1.25v(locked) i could not pas 1070mhz.

With my sapphire i can run 1200mhz easiliy on 1.25v
