I purchased this on sale to crossfire with my 5770 as I realised I could use a little more graphics processing power; overall there wasn't a huge jump in performance, but it was just as much as I needed the run my games. Only problem I have so far is when I allow the GPU to control its own fan, it runs pretty loud.

Great looking card, relatively short, fits into Shuttle case perfectly. CAUTION: THE CARD SHOWN IN THE PICTURE IS NOT THE CORRECT CARD, IT ACTUALLY HAS SHROUD OVER THE FAN and is a dual slot.
Went into a budget system, overkill for the system really but it was on for a good price. Haven't played a lot of games on it, but don't ever really intend to on it. For the normal price you would probably be better getting a 6850 though, since they can be had for only a bit more. I played with some overclocking and it ran at 950mhz core no problem, didn't push it further. The only downside is the fan is loud, quite loud. Catalyst seems to want to run the fan at 50ish % at idle even though the temps are low. At maximum load it runs almost 90c even with the fan at 100%. Gaming temps won't reach that much since they won't be 100% but still something to consider. If I bought another 6770 I would look into a card with a better cooler, or purchase a better one for it which I have already ordered.

I love this card, bought on sale at $84.99 and is totally worth it. Benchmarked it against a gtx260 and is almost even for less thank half the cost. buy 2 and crossfire for even greater value. Compact design, but has a double height bracket, picture shows single height. Other than that, short and sweet.

Really good card for the price, bought it for my uncle and he's really happy. Didn't have to change power supply since it's low on power consomption and play most game and high graphic 1080 resolution.

Bought this card for my Shuttle H67 HTPC. Asides from a 3DMark11 test (scored P2687 with my i3 2100), I havent done any gaming, or any other major tests. I have been using it mainly to upscale my DVDs, and watch HD Youtube videos on the web. For those 2 tasks it's been running great. My only concern with this card is how hot it's been running on idle (58C). I havent seen anything higher than the mid to high 60s on load but then again I havent done anything on it that required heavy GPU usage, so those temps could shoot up much higher if I decide to play a game. I've done some research though, and can say that those temps are within safe margins (as long as I dont exceed 80c, there should be no real cause for concern), but this is just a personal preference of mine I guess, since my heavily OCed GTX 570 on my other machine idles much lower than this card on stock (low to mid 40s).
bought this for the missus to replace her dead gts 220 I think it was, under $100, I'm not going to complain, considering at one point I was thinking of running two 5770 in crossfire. So. I would recommend it if nothing else around this price range, but there's probably better for not much more.

I had 450W power supply and I do not want to spend more money other than graphic card. The Radeon was ideal choice but I had hard time choose between 5770 and 6770. They are almost identical except very few feature. I heard 5770 can be updated with 6770 firmware but price diffrence was minimal. Anyway, I am sarisfiy with my choice because I play most of game with PS3 but PC game tends to become cheap faster than same PS3 game title. I also like keyboard + mouse control for FPS shooting game. The Crysis 2 was running smooth with 1080 with low detail but still excellent quality.
