Is the hardware the same?
I may just decide to get one 7970 and put a water block on that if they are performing that well. I will be playing everything at the regular 1920 X 1080 ( for now )......but I think I may end up picking up a couple extra monitors and take advantage of the eyefinity stuff. That was another reason why I was thinking of getting two cards. Just looking to the future a little bit with this build.
The following is taken from leditreviews:
At first glance the AMD Radeon HD 7970 GHz Edition (XT2) video card looks identical to the Radeon HD 7970 (XT1), but fear not it is pretty much the same card. AMD has basically just tweaked what is under the hood a bit and is releasing a new card. Most of the changes have been done in the vBIOS, but there are also a few minor component changes as well. AMD did not want to discuss what component changes were done, but assured us 100% that there were physical changes done and not just all software changes.
So there may have been some physical changes, but even W1zz says it doesn't look any different, even the pcb.
Since I haven't seen any 7970 NOT
overclock to the GHz clocks and beyond, I'd say it's not really that big of a deal. However, it does come factory overclocked so you don't have to mention that. My cards overclock to 1100 core without voltage adjustment, so I'd say they're fine.
I would suggest a 7970 and watercool it, since that's what many of us have here, and it's been great thus far! It'll be perfect for 1920x1080
