Answer 1

You are due for a new build or pre-built, most definitely.
you should be able to hit score of 14k on 6-core w/o trouble.
And for what you can get for £1799 - £2099 I think you could build one, but start with quality parts and go with a solid foundation that will be supported for years. As long as you don't need OS X as it stands.
the mac pro use to shine when it came to dual processor setups. Custom built dual PCs can be another matter, and not for faint of heart.
Choose current socket support, processor, and motherboard and you really are set for years and can upgrade from there.
Take a look at this for a start:
