BB price $69.99 on sale
My old 8800GT inside my HTPC/light gaming rig died the other day. The specs on the 640GT aren't amazing but it held it's own against the 8800GT at around half the power consumption so I gave it a shot. The live TV quality shows a slight improvement using a HDHomeRun Prime (ESPN.com scroll bar is more fluid, the intro to the Big Bang Theory is much less pixelated) and I was able to run around in Skyrim with med/high settings just fine. Other things to note is that the card does not need any extra external power, is a fraction of the size of the 8800GT, and much quieter.
I fully realize this is not a 'gamer' card so if that is what you are in the market for I suggest ignoring this post, but if you need something for your HTPC build and also want to do some casual gaming on your 65" TV at 1080p with medium graphics then this is probably $55 well spent.
