I'm hoping to get a computer on sale in the next couple of days - there are many on sale and I was wondering if there is a specific brand I should definitely stay away from? My choices seem to be HP, Dell, perhaps Sony or Toshiba. We don't use our computer extensively, I just really need to have a larger RAM to play games without crashing :O) I now have a laptop which I love because it takes up little space and I hate sitting at a desk. Would a desktop be a better choice in terms of needing to upgrade it eventually? Any input would be greatly appreciated, thank you!
