Did you think that that the HD 4890 was the last video card to come out of ATI's HD 4000 series? Well if you did, it turns out you were wrong. Sorry about that.

While the HD 4890 is likely the last high-end card in ATI's current generation of GPUs, it is not the last card to bear a new HD 4xxx designation. That honor will instead – most likely – will belong today's review focus, the HD 4770.

The HD 4770 is not just another middle-road performance video card. While it bears some similarities to ATI's HD 4670, when it comes down to performance, as you will see, there is more that is different than the same.

For the first time ever, AMD is introducing a brand new, smaller manufacturing process first in it's graphics chips, before making an introduction in a processors. Today's HD 4770 is the first video card to feature an extra-microscopically small, 40 nanometer manufacturing process. Positioned against the 65nm 8800GT/ 55nm 9800 GT, and the 65nm 9800 GTX / 55nm GTS 250, the 40nm design of the RV740 isn't the only surprise featured in today's HD 4770.

Let's get on our spectacles and take a peek at this very stimulating graphics card. Could the HD 4770 be a game-changer?
