Old computer? Just upgrade the computer memory

It was a hard thing for me to part with my laptop of 3 years now so instead of dispatching it, I just thought to upgrade the computer memory to its maximum capacity of 2 GB and add a few tweaks so it works better now. It was a Dell memory that I specifically needed to make it work better and I was able to purchase this online from www.memoryupgrade.pro and now that it is working faster and better, I still cannot use it for work so it is now used for fun where I play online games on it. But as for work I bought a new macbook with a powerful 4 GB Mac memory and surely that is way more better than anything else. But still, my old laptop has a sentimental value hence I don’t want to get rid of it.
