New computer...

So I'm considering building a new computer, and am wondering, you think I can get anything good with £200 (about $380). I'd need:

RAM
Graphics Card
Processor
Motherboard

Everything else I already have. Any suggestions are welcome, thanks in advance.

Get an awesome (CRT) monitor for £200 instead.

I've already got a 19" Flatscreen, and my current computer is absolutely rubbish (integrated graphics, celeron processor etc etc)

With that money, I'd buy a preloved computer from a serial upgrader
