Thanks for the reply. No I'm not planning on gaming on it, just running a lot of fairly demanding software.
Please could you recommend specific parts to get? As I said in the first post, I really don't know what I'm doing Money is an issue but not a huge issue as a friend will bring the parts back from the US for me and your parts seem sooo cheap! Are there any other specs or anything you need to know from me before you can recommend stuff?
