I decided it was time to move up, a little, from the ATI 4850, to another series. The 4850 is a high end card with DDR3 RAM, which is less than this, but has the 256bit interface that this card doesn't. Is it a big deal? Well somewhat, but nothing major. The 6770 definitely runs cooler, and mine was also getting some age on it, also the frame rates on "some" games is a lot better as well while using higher anti-aliasing. Take Resident Evil 5 for instance, at full 1080p, 0 or 2x AA, the 4850 top out at about 54fps, which wasn't awful for an older card. And would drop down in the lower 30's at the most. The 6770 maxed out at about 96fps on RE5 at 4xAA,and never drops below the mid 70's, which is quite a stretch. So why do i say somewhat? Well you really wouldn't think you could tell much difference between the 256 and 128bit interface, i can. It's nothing to sit and wine about, but certain textures, people, landscapes etc seem a bit more washed out than with the 4850. Also if you go to Hardware Compare, the 4850 still out performs this card in one or two categories. But overall i'm very happy with the performance of this one. All games can be maxed out without any problems, sure some games have some lag, but usually thats a buggy game and not your system or card. I have an Acer M5800, with 8 gigs of DDR3 RAM, a Core 2 Quad 9400 running at 2.67 ghz. So it's quite a beast even by todays(2011) standards. The DDR5 is what gives this card such an advantage, as with most of todays mid range cheaper cards.

I tried an Nvidia 550i and wow was it bad, it was suppose to be a bit more powerful, but the framerates were not different, it ran at over 62C, while the highest temp on this card has been around 48, even with hardcore games. Maybe 50.

A Radeon HD6770 card for $90, after rebate, represents an enormous bang for the buck with respect to performance. Nothing else really comes close in this price range. However, XFX decided to not use the reference design for this card and as a result it runs hot and loud with no over-clocking headroom. My reference design XFX HD5770 (same GPU, less features) in another build runs extremely quiet and cool even with a 10% overclock. This card sounds like a vacuum and will hit 80-85C when stressed out in BF3.

The heatsink and fan are absolute garbage on this card.

For only $90 after rebate, I'm not disappointed with this card. I upgraded from a 4.5 year old 8600GT to this and was expecting the same level of low range performance, since that's about the price I paid for the 8600. This card however, is a behemoth compared to my old card, which only took up one slot. I bought this just to play SWTOR with, expecting to run on medium settings at best. I set the graphics to max just for fun and it runs fine.

The only issue is that the fan on this thing is SUPER loud. Loud enough for me to hear it over my headphones when I'm in game. I wasn't looking to build a quiet system, so I didn't think it would be a problem, but now I'm wishing I would have looked for a card who's reviews touted a little quieter option - hence the 4 stars.

All in all I'd buy this again if I was limited to a ~$100 budget.

I bought this to be able to play some games I was really interested in, mostly graphic-intensive RPGs such as The Witcher, The Witcher 2 and The Elder Scrolls: Skyrim. So far it has not disappointed. I can play those games at a very good detail level, with smooth framerates, on a 24" monitor with a 1920x1080 resolution. Skyrim, the most recent one, auto-detected my video settings and set the graphics to High. It looks great, and I haven't had a problem with frame rates. I have it paired with a Phenom X6 CPU and 16GB RAM.

All for under $100 (after rebates), I think this is a great value for playing newer games without spending too much.

I bought mine a little over a year ago. It worked great then, and still does, but as always happens with electronics it has been out-classed by the current generation of video cards. Still, if you want a decent card at a good price, this is it.

One issue I had with this thing is installing it: I had to use tin-snips and cut a section of my tower case in order to make it fit because it takes up TWO back slots even though it only uses one slot on the motherboard.

Another issue that was easily fixed: the wiring for the fans is long and loose, so it was getting caught in the fan blades and the thing would stop spinning and overheat. So, I took the loose cables and taped them up out of the way against the inside of my tower case. No more tangles.

Xfx is renowned for their good warranties, which I have experienced and do agree.
------------
Xfx did all right with this card for the most part.
It gets pretty toasty at the load temperature, reaching about 85 c in demanding applications such as mining.
------------
The voltage cannot be changed to overclock, but It is not necessary as the voltage is already at its maximum out of the box: hence why the load temperature is so exponential over similar cards that aren't factory overvolted.
------------
Besides the heat generation, the voltage isn't really a con due to the fact that this 6770 is capable of reaching 1GHz + if it is able to take the heat. Also, to compensate the Extra voltage Xfx has taken into account keeping the vrms cool, and they added a heat sink to the vrms which is a very good touch in my opinion.
------------
I do suggest getting an good aftermarket gpu cooler, such as a Arctic Accelero Mono Plus If you want to stay below 80c, I have one on my Msi 6770 which had a load temperature of a even greater magnitude.
------------
Also, Even though it uses VLIW5, which is less efficient than the current Amd GCN 7000 series architecture. It offers more shader cores, and is on par with the 7770 in performance only requiring just a little more power to get there. Which is like 15 extra watts at full load.
------------
This card for me is running Skyrim smoothly at Ultra settings. With Anti Aliasing disable however, and using FXAA instead.
Overgrowth runs at 200 fps, and Is still in development, So I expect those numbers to slim down.
Minecraft runs at 350+ fps for me, but that is also a cpu dependent game.

All in all, this card performs quite well for the cost it is listed, and is for the most part worth the investment.
I would suggest Getting the Msi Version though, just because its a little trickier to install the aftermarket cooler on this XFX card, because it does need it.
