Is it possible to upgrade my motherboard+cpu+ram using older components?
I only use my computer for word processing, viewing videos/flash sites/browsing the web, playing old games like Starcraft and Diablo 2, and streaming internet radio off winamp. I'm looking to just increase speed of my computer from a 500mhz celeron processor to something around 2.0Ghz processing speed. I currently use a Emachines eTower 500i and just want something faster. Basically just replace the motherboard + CPU + ram with something newer, while keeping everything else the same.
If it's possible, I've deided on a Pentium 4 processor but don't know what type of motherboard to get and whether my old video card + ethernet card is compatible with such newer motherboards. Concerning P4 processors, I am not sure what bus size and L2 cache size are. I've read on some hardware guides that not just processing speed is that important as much anymore. So I'd like to know what exactly am I looking for in a p4 processor?
Once I figure out motherboard + CPU I can easily find out what type of ram I need, I just need a help on determining motherboard+CPU.
