I have a laptop with Windows XP on it. I need Vista or 7 to get my tv tuner card to work. So I used my 64-bit Windows 7 to try it and it said the CPU didn't work. I am pretty sure it's because my laptop is older and doesn't support 64-bit mode. So I sent the 64-bit back and am getting the 32-bit version to try it. I was wondering if 800 mhz and 512mb of ram is enough for Windows 7 to watch youtube videos, surf the net, and play some games, not graphic intensive games though. It said it is under the recommended amount but I am not going to be editing video, etc. I just want to connect it to my HDTV to watch youtube videos as well as surf the net and play some simple games on it. Thank you!
