OK. Sounds like a complete noob question, which I'm really not. Honest! I want to take my Stock Dell POS and upgrade parts of it. Notably the RAM and Dual Core CPU. Are there any easy ways to find out exactly what will be compatible? I want to take it to a quad core, and since Vista seems to think my RAM is not all that great, I assume that upgrading it to a decent pair will help a bit. I think that main issue with the rig is that dell use cheap parts.
