I aqquired an old HP Pavilion 8760c with a 733MHz processor, 384MB RAM and 40GB HDD. I need it in my brothers room who will use it for games on websites such as addictinggames.com, nick.com, cartoonnetwork.com and other sites that have flash based games. As of now I use Google Chrome and whenever I access any of those websites my CPU jumps to 100%. Is it worth upgrading the processor and RAM and working on the system or should I just give Windows 2000 a try? Currently I am running Windows XP Professional.
