ATI Avivo™ HD Technology
ATI Avivo™ HD is the advanced image and video processing and display technology found in ATI Radeon™ HD GPUs and ATI Theater™ video capture processors. Specifically designed for HDTV and HD video enthusiasts, ATI Avivo HD provides brilliant colors, sharp images, smooth playback of Blu-ray™* and HD video content, HDMI with built-in multi-channel digital audio, and on some GPUs, Unified Video Decoding (UVD). UVD is designed to enable a cool and quiet media PC with low CPU power requirements and playback of HD 1080p content. HD Monitor is required for full 1080p enjoyment.
HDMI Video and Audio
A system with an ATI Radeon™ HD 4800 Series graphics card can help enhance the HD entertainment experience by providing a seamless connection to an HDTV or home theater system. With built-in 7.1 surround sound audio (AC3 / DTS ), the new GPUs and graphics cards support single cable connection directly to a compatible HDTV, projector or receiver. This single cable carries both the HD video and 8 channel audio for a clean, high definition connection. Some graphics cards will be equipped with an HDMI connector, while others will output the HDMI signal using a special ATI Radeon DVI-I to HDMI adapter. These options give consumers more options and flexibility when connecting their PCs to monitors or home theaters for maximum enjoyment of HD content. The new GPU also supports xvYCC color which can display a wider range of color when connected to capable HDTVs.

Nice card, looks great if you have a clear case or window in the side of your box. Used this for a customer build who thought it was great, ran everything he threw at it, however he complained about fan noises during gameplay. I looked into this for him and found the GPU to be running quite hot.
There are better options for this price range.
bought this for my first gaming rig for 229$ it was the price of a 4850 and im happy with it, with the 8.12 and later drivers the heat problem is gone, idle at 45 celcius and load at 60 to 70 is really good, paired with an e5200 its a killer, i play all the new games at full details even crysis its good enough since at very high the bottleneck is the cpu not the gpu and i manage 25 to 35 fps on a 1440x900 resolution, L4D 120+ fps, same thing TF2, bioshock, unreal 3 and other games. and with the 4800 line ATI is back and the drivers are really good now and its improved specially if u have 2 of these for crossfire. manage to get 790 Mhz and 1050 Mhz and more but no need as the default speed is enough for anything that u can imagine, with a quad core the crysis days r over. ( by the way i hate that game)
Got this thing on boxing bay for a real good price and it has done its job remarkably well. Had a 9600gt and obviously this thing blows it out of the water. Supporting the competition is also a bonus imo, works out well for everyone.
I must say that Team Red is now back in the game with video cards, and at these prices they're very competitive I had to see this for myself to believe it, Sure it runs hot but it was built to take it, I'd reccomend this to anyone who's on a tight budget that wants great performance
Just look at all the reviews for this beast, it's still unbeatable. I am a huge Nvidia fan but this was just too tempting, Ati has finally made me a fan of their vidoe cards with this. Very very very good card, highly recommend it.
This is a great card. I highly recommend you buy this. THis card can run every game out there max settings with decent FPS. I bought 2 of these and I can easily run Crysis Warhead maxed with 4xAA at 1920 x 1200. Amazing card. There are a few weaknesses but those can be fixed. The card used to run hot so I just edited a profile and now have the fan at 45%. Now the card never goes above 70c. Although the biggest downside is warranty because no ATI partner allows for after market cooling but you wont need it for this card.
Overall, this is an amazing card. Games have never looked so good, or played as smoothly. It was a huge upgrade over my aging 1950GT. The only downsides are, at this moment there are no ATI approved methods of raising the fan speed, and in turn lowering the ridiculous GPU temps. An idle of 70+ degrees is not acceptable. A quick Google search, and you'll find there is an answer to the above issue. Still, ATI should have done this themselves.
