Ugh - yeah. Messy. Very messy.
Still a good card at its original specs as well, don't get me wrong - but there's going to need to be serious caution if someone wants one with the faster memory. And, given that AnandTech's analysis said that most of the performance gain was from the increased memory speed, that's the one that I want.
Hell, for my son's use, I might see if I can, say, get the Pulse with the new BIOS, but then drop the GPU speed down to the lower settings. Some nagging corner of my brain wants to get the best fps/watt out of this rather than maximizing performance. And, at 2560x1080, this card won't need to be pushed to its limits yet.
