Are you asking about your Internet connection speed or your PC's performance. The upload/download numbers refer to internet speed. Your PC's hardware appears to be a bit dated but even that equipment will easily handle much faster internet speed than you seem to have. You did mention it's a lower speed connection so I'm thinking something like what was called "DSL lite" or an equivalent cable offering. These are the usually the one companies offer at rock bottom prices like 15 bucks a month and are for people who mostly do email, on line shopping, etc. It's not adequate for much in the way of streaming video or gaming. In any event, your numbers don't look that bad for basic internet use but you're not going to like it for youtube, hulu and such. As for your PC, if it's too sluggish for you, the best option is to get something newer. But I would agree that 512 megs of RAM is a bit marginal. Windows XP does reasonably well with 1 GB. Beyond 1 gig, further improvement is just about unnoticeable for most purposes. Some will suggest a better graphics card instead of RAM at some point. If yours is AGP, you'll find these hard to come by now. Hope that helps.
