Anyone who has built an HTPC machine that they want to use in the living room for streaming video and content to their TV and for playing video games knows that there are tradeoffs that have to be made. The tradeoffs come when you are using a HTPC chassis that only allows low profile video cards, the more powerful video cards don't typically fit into these cases.
PowerColor has announced that it has a new video card made specifically for HTPC machines called the HD5750 Low Profile Edition. The low profile card uses a pair of cooling fans to keep the card cool even though it is going to be in a compact space. The dual fans and the heat sink cover the GPU, memory, and the MOSFET to cool all heat generating components on the card.
The low profile beast has a core clock of 700MHz and a memory clock of 1150Mhz with a 128-bit memory bandwidth. The card also supports Eyefinity, DirectX 11, and CrossFireX. The outputs include DVI, HDMI, and VGA. This may be the best little video card you can find for an HTPC machine. PowerColor is mum on the price and availability of the card.
