Buying Computer-Don't know alot about computers... requesting help?

Well having not bothered to look at what you're going to buy, I would tell you that it would be more important where you bought it and not necessarily which one you bought. Best Buy will give you better support than walmart. If something happens with the one from walmart where are you going to go? They don't have any service for their computers or any of the other electronics they sell. Best Buy does. So if something went wrong, you could go back there and they would be able to fix it for you. Good luck with that at walmart.
