We have a 720p Olevia 42 LCD tv in our Cultural Museum. It has a native display of 1366 x 768. I want to get a computer that will match up to this diplay. Any recommendations on a video card that would work well with this display?
It ties for 1st place with the HD 5670 in terms of overall video quality (see link below). For gaming purpose, the HD 5570 is equivalent to the HD 4670 which was a pretty good mainstream video card. The HD 5670 provides roughly 30% better performance than the HD 5570 (HD 4670).
Need a little bit more information about the computer you are going to use. Are you building one from scratch, intend to buy pre-assembled or do you have an existing machine that just needs a video card upgrade?
If the later, you do not need a really zippy machine, but make sure the card you buy will fit into a PCI slot you have available.
If buildign your own, you may want to consider just getting graphics processing integrated into the motherboard, and save some coin. The Intel Graphics Media Accelerator (GMA) 4500 scored quite well. Here is a $99 board from NewEgg: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
If you just want a dedicated GPU to toss into an existing PC:
