Cheap upgrade over on-board graphics - provides great HD video capabilities
1 July 2011
Summary: This card isn't going to wow anyone with it's performance in new games or graphics-intensive design programs. I bought it because I wanted a discrete solution for watching videos on my computer while the computer is doing other things. It's really only a slight upgrade from on-board graphics, but that's all that's really needed.
Summary: If you are looking for a low-end, low-priced video card with high-end performance, then look no further. I just recently grabbed one of these (used) and it's the perfect video card for a backend HTPC system (especially when the mobo is also Gigabyte :) or even for a frontend one with an HDMI connection.
Summary: The ATI Radeon HD 4550 512mb card is a great card for those who would like to improve their performance without spending 2 much money. It's not a great gamer card even though it gets a 6.3 on the windows experiance index in gaming and business performance. Where this card really shines is video acceleration, you could be running a core solo or an atom processor (if you have a PCIe slot on the atom board) and you could playback pretty much anything you could throw at it.
Summary: I only use it to record JVC HD Cam Corders with Adobe OnLocation I got it because there is no fan and because of that 100% silent for studio work. It only takes up 1 PCIE place where all the other non fan graphocs cards take up 2. Placed it in a shoe box computer from shuttle, no idea on how it plays games but I don't use it for that.
Summary: Use this card for light gaming, plays starcraft 2 pretty well, and for home theatre. Card uses DXVA or hardware decoding to view 1080p video flawlessly, I use a program called "media player classic home theater". It also accelerates Flash, so 1080p flash video is finally silky smooth. Had this card for a little more than a year now, and no problems yet. I also like the low energy requirements, and low profile so it will fit in almost all cases.
Summary: I bought this through a seller and not from Amazon. Works great and it was only $35 with shipping. Got this because it has an HDMI port so I can connect to my TV also. Had no problems on the TV, ie. overscan issues. Haven't tried games on it yet but don't expect too much, this IS a low powered card. Would have like to have gotten a higher performance card but I didn't want to upgrade my psu. This was perfect because it only required a 300w psu.
Summary: I bought this GIGABYTE GV-R455D3-512I video card for use in my HTPC. It does not work well for HD video playback. The hardware acceleration features (ATI's UVD) of this card were unable to properly process DXVA compliant 720p and 1080p videos using MPCHC. These same videos play flawlessly with DXVA on my other PC with an Nvidia GTS250. The "screen cooling" is only a piece of metal bent around the loosely mounted heatsink's cooling fins.
