1 out of 5 eggsit's a gamble

Pros: High performance at low price

Cons: high failure rate and poor RMA support. This card crashed both of my two computers after the BIOS update and with the latest and other versions of drivers. I upgraded too many components at once to isolate the failure to the video card in Newegg's return period. Gigabyte's RMA returned with no status other than "testing complete" and the exact same problem persisted.

Other Thoughts: failures happen when trying to produce this technology at this price, but unsatisfactory RMA service is a mark of a don't-buy supplier for me.

4 out of 5 eggsGood Card

Pros: Cheap fast will run most source games maxed out. Runs cool due to die size and very low power good for HTPC if you have a full size PCI-E

Cons: Some confusion online about bios problems. My card did not have any but others have so be sure and update it when you get it.

1 out of 5 eggsMore like a refurb

Pros: Good price if it works

Cons: The card has the same issues mentioned in other reviews even with the updated firmware. The card I received looked very dirty (like someone wiped the pcb down with wet cloth). There were also small hairs on the pcb along with scratches on the heatsink. Newegg claims the card was brand new and beside the card itself all the packaging looked new from the factory. Maybe Gigabyte is sending their RMA stockpile back to the production line?

Other Thoughts: The first thing I noticed when I took the card out of the package was how dirty it was. This card did not resemble anything that came from a production line. I emailed Newegg photos of the card right next to the package I took it out of and they did not seem to care.

4 out of 5 eggsPleased

Pros: Got this so I could have 3 monitors and do an eyefinity setup. So far it has great graphics for BF3 on one monitor.

Cons: I've had a lot of problems with they eyefinity setup because of the minidisplay port to DVI converter issue. It wasn't something that I was aware of before I bought my rig. I feel like it is something the manufacturer should be more upfront about warning people about.

Other Thoughts: I will probably get my eyefinity issues worked out with better adapters so no big there.

1 out of 5 eggsDO NOT PURCHASE

Pros: Good specs for the price, I guess

Cons: This card slowly died on me over the course of about a month, and is now basically unusable for gaming or running any OpenGL or Direct3D programs. When running a game (any game, regardless of how demanding), the game will freeze for a couple seconds, followed by a black screen. The computer will then return to the desktop, with the game not responding. At first, this happened every few hours - it now happens at least once every hour, generally within twenty minutes or less of playing. The card is not overheating (stays below 60C even when crashing), and I've checked my memory with memtest86+.

The actual error Windows gives, under Control Panel->Admin Tools->Event Logs is "Display driver amdkmdap stopped responding and has successfully recovered." Looking only, this doesn't seem to be uncommon, but none of the remedies have helped - using driver sweep to completely reinstall drivers, adjusting the idle clock rate, nothing. Judging from the other reviews here, it seems to be a bad...

Other Thoughts: (Continued)
... batch of cards. Seriously; the failure rate on this thing is unacceptable, and of course newegg won't RMA it because I've had the card for a couple months now (issues don't appear right away). It seems that the card is now discontinued, so at least someone knows something's wrong - if only I could contact Gigabyte for a replacement, but the link in the product page is broken and I didn't get an answer at the tech support number. I hope I can at least get a response from them that doesn't involve putting my computer out of commission for a month....

All in all, terrible customer experience. Would not buy again.

4 out of 5 eggsNo:2_OK

Pros: The spec's. and the price. runs prity cool. prity quite.
and i didnt have to burn-up a weeks pay to get it.
lets hope i get my moneys worth out of it.

Cons: The first one was a bust but No:2 is OK. execpt it dosnt like to be awaken. if the computer goes to sleep on its own after a set time it wount wake from key board or mouse. it has to be restarted from the main power button, which logs an error and asks if i wnat to start normaly. hence the 4 out of 5 stars.

Other Thoughts: I dont use sleep so its no big deal for me. i tryed changing some bios settings. but havent really followed up on it. it plays all games and in 3D. so for me its a keeper.

4 out of 5 eggsRebate in 4 weeks

Pros: Newegg and Gigabyte Rebate process can split the stars.
Card itself doesnt deserve any.
Got my quick option (18 instead of 20 back) rebate in less than 4 weeks really 3 weeks from the time i mailed it until it hit the cluster box.

Cons: This card had good intentions to fill the large gap between 7770 and 7850 and for less than half the price 90ar compared to 200 for the 7850.But it was just to buggy even with 12.7b and f5 bios.

Other Thoughts: sometimes you read the reviews and see a really great price performance deal on paper and think to yourself...

even thou i see all these bad reviews ,i know what iam doing and can just make it work...sadly most times that is just not the case.

4 out of 5 eggsGreat card but has driver issues.

Pros: Runs most of my games on ultra/very high with no lag at all. Paired with my i7 3770S and with PCI-E 3.0, it can sure get the job done. I forgot all about getting a 6850.

Cons: Unfortunately on windows, when my monitor goes to sleep, the card never wakes up until you do a hard reset. I had to change my settings so the monitor never goes to sleep. Maybe I'll try setting the screensaver to "blank"

On Ubuntu, when the monitor goes to sleep, it wakes up immediately, but when scrolling on Firefox, sometimes I get random black bars at the bottom of my screen and occasionally my video will freeze and "glitch" momentarily.

Both issues I believe to be the drivers, and not the card.

Other Thoughts: AMD needs to get off their hineys and fix their drivers.

1 out of 5 eggsGood at first

Pros: The card can run most games I throw at it.

Cons: The card worked fine for about a week. While running anything in full screen mode (i.e. games or video) the screen would freeze for a few seconds, go black and then return to normal. At first, this only happened about once a day, then a couple times a day, then almost every hour. Currently, the card freezes after around fifteen minutes of full screen use. I can no longer use it for gaming or video, so I am now in the market for a new card. I am sorely disappointed with Gigabyte and with this card.

Other Thoughts: I would not recommend this card.

1 out of 5 eggsDO NOT BUY! Fast, but very buggy!

Pros: HD7770 GPU at 1100 MHz. Quiet fan.

The HD7770 was within 10% of HD6850 / GTX460 1GB using the launch drivers, within 5% using catalyst 12.3, and with cat 12.7 passes them. This one is overclocked by 10%, so it is even faster. While in older games the HD6850 / GTX460 still might do better, the HD7770 beats them in newer games (BF3). Furthermore, in some games where its average fps are lower (Diablo III) its minimums are higher, hence better playing experience.

As you could read, the pros are mainly to the HD7770 GPU, not to this card. This specific implementation of the HD7770 by Gigabyte is probably the worst of them all. It doesn't matter if it is probably the fastest HD7770, because when it keeps systems crashing and crashing without any specific pattern, it makes the computer ownership a pain. Gigabyte is losing its touch.

Cons: All HD7000 series card were affected by the "deep sleep bugg" (DSB) This bug was the computer would freeze if the monitor was allowed to go blank (sleep) as trying to get the computer back to life with the mouse or keyboard would be fruitless. Computer had to be restarted.

The bug wasn't fixed until cat 12.6 (cat 12,4 fixed it for some) almost all the HD7000 series card were ok with cats 12.6. Not this one. Cat 12.4, cat 12.6 or 12.7b, this one still had the DSB. While it was very stable when awake (I never had a single crash) the newer drivers didn't help it with the DSB (deep sleep bug)

To fix the deep sleep bug, Gigabyte released newer BIOSes F4, and then F5. I own a total of 6 of this cards, all in similar setups (970 chipset boards, 5 960Ts and FX8120s, win7 ultimate amd64 sp1 up to date) All the six had either F1 or F2 BIOS, so all of them had the DSB.

Even with F1 or F2 BIOs, all of them were very stable during normal operation, be it gaming or just web browsing

Other Thoughts: CONS CONTINUED

When I updated the BIOS to F5 in 2 machines, the DSB bug was gone, but a newer nastier bug appeared: The computers would crash in the middle of normal operation with grey vertical lines on screen. Those computer had cat 12.7b, but they never crashed with F2 BIOS. The crash is random, it can happen during web browsing or loading web flash videos, or as simple as word processing.

A 3rd machine was updated, that machine had cat 12.4, but also stated crashing. I got in touch with gigabyte tech support, who were unable to replicate the issue, but suggested using cat 12.6 WQHL. I updated to F5 in 2 other machines that have cat 12.6 WQHL, and guess what? They started crashing also! Sometimes the computers can last a whole day without crash, sometimes it can happen after logging in.

Reading the other reviews, I can see all of us having issues are using AMD CPUs. I wouldn't be surprised if these dummies are looking for a intel string or so. Just fix the bIOS gigabyte!
