4 out of 5 eggsSo Far, So Good

Pros: Relatively short compared to many other graphics boards on the market, so will install in tight cases.

Runs fine with current AMD driver set (11-8).

There's not much else to say at this point. It's driving two digital monitors (1680x1050 and 1280x1040). The most demanding game this will face is Sims 2, which it runs smoothly with all settings maxed.

Cons: Given its relatively low power requirement, runs a bit hotter and with more fan noise than I would have expected, but neither are excessive. According to GPU-Z, the GPU temp tops out at around 71C at full load.

Other Thoughts: It's a bit early to draw any firm conclusions, but after a week this product is working without problems. The heat and fan noise are in line with what I have read in online reviews.Compared to other boards on hand (HD 4830 it replaced, HD 4770 in my machine, and HD 6850 that replaced it), this HD 6770 runs both hotter and with more fan noise. Under load, the fan is clearly audible over the other system noise.

Four eggs because of the temps and fan noise. It's true that I did not carefully research these two aspects of the board prior to buying, but now that I have the board, I would probably choose a different one if I had to do it again.

The 03/2011 WinXP 32-bit driver download for this board on Gigabyte's Web site does not support the board.

Associated components:
Gigabyte GA-EP45-UD3L
Intel Core 2 Duo E7400 Wolfdale 2.8GHz w/Arctic Cooling cooler
Cooler Master Centurion 5 CAC-T05-UW
Corsair VX 450 power supply (the minimum, but have a TX 650 if needed)
