I bought two of these cards for a Crossfire configuration, and they are truly amazing in terms of performance. I was running a single-card nVidia GTS 450, and even just one 6770 blew it out of the water. With both cards, I get a stabilized 60 FPS in games like Borderlands and Deus Ex: Human revolution, with all settings maxed out at 1680x1050. I never dip below 55 FPS, even in intense scenes. I have been getting 120 FPS and up in Serious Sam 3, which is awesome.These cards are also very gratuitous on power consumption; I am running both cards on a mere 500-watt power supply. I do need to upgrade the PSU though, since games that overdraw resources, like Serious Sam 3, actually overload my PSU and shut my computer off. I should note that my motherboard, fans, and video cards are the only devices that draw power in my computer - I have no peripherals. If you have several optical drives or other internal devices, you may not be able to skim by on a 500W power supply like I did (assuming you do Crossfire).I have a full-tower case, but this card is only about nine inches in length, compared to my 450 GTS, which was damn near a foot long. You can easily fit two of these guys in a mid-tower case.You'd better not be picky about the noise level of the card, because it is fairly loud. I don't have silent fans in my case, and I can recognize my GPU fan over the rest of them.My only complaint is that the product did not come with a Crossfire Bridge, and I had to purchase one separately. This does not affect my review of the product, as it has nothing to do with performance.

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. So I choose to stick with ATI, being that they are just better reliable cards. So here are some games to give you an idea of the 6770's performance.NOTE-You don' HAVE to max out your resolutions etc. It will play even better at lower 1600x900 or 1366x768, with even quicker performance. I just like the eye candy and to push the card to it's limits.Crysis 2-Advanced Setting-Full 1080p, In the low 50's at times, lower drops to 32 or so in high action sequences. Which still buries consoles.Fear 3-Highest with 4xAA-around 55 fps, drops to 44 or so. Full 1080pBioshock 1 and 2-Both are up close to (or over on the first game) 100fps all settings maxed Full 1080pAlice Madness Returns, not a real demanding game, but great graphics-Around 65 or so on highest setting, lowest around 50 or so. The game has some glitches, so you may need an update.Call Of Duty Black Ops-Full 1080p, highest around 50 or so, lowest about 34 with lots of action.Dead Space 2-Flawless- around 65 or more, the whole time, game looks stellar. No glitches to speak off. Full 1080p.Assassins Creed 2-Stays in the 40's the whole game-Full 1080p, 4xAA. Pretty demanding game for what it is.Red Faction Armageddon-THQ are known for their graphically demanding games. At full 1080p, 4xAA, it stays pretty much in the upper 40's, some drops in the 30's. Still not bad.Call Of Duty 4-Modern Warfare-All maxed out 16xAA, full 1080p-around 120fps in some areas, the lowest about 55 or so.Bulletstorm-Pretty Demanding-Full 1080p, Direct X 11, 4x AA, uppper 40s lower 30s throughout.Those are the games i play or have played most, i'm going to try Metro 2033 soon, for a good test. I'll update it later. But as for now this is a great card and just slightly over the 5770 that came before it. I myself see a pretty big performance boost, although some may not. Now i'm just waiting for RAGE and DEAD ISLAND to really see what it can do. Can't wait. Hopefully it will run great. But remember, you also need a great rig, with good ventilation which most gamers know. Also the card is HUGE so don't go trying to stick it in your parents HP, or Dell tower they bought from Best Buy. Unless you wanna upgrade the whole thing, but then again the card wouldn't fit anyway. I recommend the Acer, and just an Acer tower in general with higher specs. They are very reliable, no crashes, NEVER a blue screen, ventilated well, VERY wide, and perfect for making a gaming rig, and i got this one in 2009(running strong). Also inexpensive. So for the price you can't beat this card, i wouldn't purchase the Nvidia 460, to save my life being that it runs way up in the 70's(degrees C) all the time. I had that card for one day this year and kept my old 4850 till i purchased this. So my advice "get this" you'll be glad you did.Also, one last note, the card looks NOTHING like this one in the picture. I got mine at BB, it's sleek, orange and black, no fans or anything sticking up. Looks more like a large block.

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.
