4/ 5

Pros: Works well! I havent had any issues using this board.
When I bought it it was one of the cheapest x16 pcie boards around

Cons: Doesn't allow crossfire of cards ahead of a radeon 3300, so if you plan on x-firing, you may want to look at another board!

Also

Overall Review: the second 16xpcie kills off 2 of your 1x pcie's. Be aware of this!

Exceptional - Now Have Four

Pros: I now have four of the GA-MA785GT-UD3H motherboards. They all perform flawlessly. I used 4GB of GSkill memory with each, I selected a GSkill part number that was specfied by GigaByte. All have different processors for specfic use. One was built as a Win 7 Media Center PC, two are general XP desktops, a Windows Home Server. The Media Center plays Blu-Rays flawlessly at 1920x1080 without having to add a video card. My Home Server has been running for over 30 days since the last reboot for updates.

Cons: None for me.

Overall Review: I am not a gamer so graphics performance was not an issue for me. However it is nice to have slots available to upgrade if needed.

bad sata controller

Pros: unlocked Phenom II 555. I'm a past fan of Gigabyte. I like the dual bios and heavy duty caps, but this install was BAD.

Cons: ruined two hard drives

Overall Review: Out of >30 system builds I have done in the past 20 years (incl upgrades and new builds) this was by far the most frustrating. After 20 hours of work (incl. 10 attempted repair/fresh XP Pro installs, two ruined hard drives, hours of formatting and data recovery tools (only got about 1/2 of it back). Note: Same with shipping BIOS and update to Rev F7.

Final verdict= bad (but not completely inoperable) SATA controller. This board should not have passed QC. Need RMA.

What a mess

Pros: rma replacement board, newegg's rma works great

Cons: bad integrated graphics again, screen corruption until it hard locks, tried to underclock the on-board graphics core with no luck, it crashes sooner with it underclocked, 2nd board with this problem. ps2 combo port doesn't work. it won't detect my flash drive to use q-flash to update the bios, it says my flash drive is a floppy instead of an hdd

Overall Review: extremely annoying that the replacement board is worse than the 1st one, maybe 3rd times the charm

Bad on-board video

Pros: Looks nice, nice upgrade potential, cheap

Cons: integrated graphics is broken, won't boot into windows without locking up, usually happens at the starting windows screen in win 7

Overall Review: tried to save my customer some money by using the integrated graphics, since it didn't work, the only thing this board has done is cost me money for return rma shipping

Dependable Motherboard

Pros: Low Price, dependable, great features, video on board, gigabit on board

Cons: Raid isn't supported by ESXi last time I checked.

Overall Review: I use these motherboards in my server and workstation setups. They are very very dependable and I haven't had any go bad yet. I have 10 or 12 that run full time without issue for at least a year now.
