ASUS GTX780 Ti Matrix Platinum Review
When the underlying GPU, the GK110, is so strong then it's in the tiny details that the differences can be found. Areas that to the average user will be meaningless, or indeed pointless, will be hugely important to those on the bleeding edge of clock speeds and cooling solutions. If you've ever suffered from a cold bug when you're trying to restart the card under LN2 you'll appreciate the molex power connector which allows the memory to defrost. As we say, things that will be of no importance to most of us, but awesome if that's what you're into.
We still don't believe that the colour-changing LED is a good thing and no amount of PR waffle will convince us otherwise. GPUs tend to run at either no loading on the desktop, in which case the thing is blue and doesn't match the rest of the card, or it's under 100% load in which case it's red, which it should be all the time. Just stop it ASUS.
The two main things that affect how well you can overclock are power stability and thermal limitations. The Matrix hopes to get around these issues by utilising nothing but the very highest quality components in the power phase, and utilising the dips and ridges in the cooler to keep it as cool as possible.
