Andy - the more RAM the better I say. RAM is an abbreviation for Random Access Memory. RAM is the computer's main memory. The computer uses RAM constantly to temporarily store information while it is working with it. So the more RAM you have, the more stuff can be stored as the memory is bigger. While this won't really help a lot with web surfing (tho it does to an extent I belive with images and what not) but the main benefits will be with running programmes and multiple programmes/windows open at a time, and will show up a big improvement when it comes to gaming and things like ripping and burning CD's/DVD's...

I notice a pretty decent improvement with my 1.5gb of ram comparred to my other PC's 512mb - likewise the other PC to my old ones 256mb RAM....
