How long do you plan on using this machine? Within a few months it's going to be very risky to surf with XP. Is it really worth it? For just a few hundred dollars you can get a new machine that's *much* faster.
I know that seems like a lot. But, how much is it worth if you catch a malware that downloads something that crashes your machine and loses all your photos and documents? Or, downloads a keylogger and they get into your bank and credit card accounts?
How long did this last machine last? Probably at least 8 years? That probably works out to around $50/year. I expect your next machine will have an even lower cost/year.
I have a couple of secondary XP machines that I'm retiring. I may reformat one and use it as a MAME machine, or some other dedicated function. But, I don't plan on ever surfing with those machines, again.
