I'm really digging some of the high performance SFF stuff coming out lately.
Gigabyte is making a new Brix PRO version (per TPU) with a GTX 760M GPU. I bet the unit will be too expensive like the other Brix units, but it's pretty darn cool I think. These devices and GPUs are fitting form factors that were unthinkable a few years back! Cool stuff.
Oh that Brix PRO has a 4900MQ level processor with a GTX 760. I believe the 760M is basically even with the desktop variant, it's a fully enabled GK104 GPU. Should be pretty cool. Probably too expensive, but that's always the case with newer things. A couple of years from now, I bet we'll be able to get insanely good GPU/CPU performance in the size of a box around double the size of an Apple TV I bet. Desktop will still be better obviously, but SFF has come such a long way. And that's pretty neat stuff.
