I have a number of simple questions about computers. I know enough about computers to use them, but with all the recent changes and upgrades, I'm hoping someone can tell me a little more. I am looking for a desktop computer that is a good brand name at a reasonable price (within the $500-$1200 range) that is compatible with the accessories sold at Wal-Mart (locally, Wal-Mart is the closest place to shop in my area, the nearest electronics store is two hours away). I would also like to know how much RAM and memory capacity I should be looking for in a computer where I would be installing a TV tuner to edit home movies and video clips, as well as several paint shop and word processing programs, but I don't need any gaming capabilities since I don't use my computers for games. I would like a computer that has a good processor as well. Any help on just some basics of the new computers would be appreciated.
