My Computer Waltz: Slow...Slow... So So.. Slow!

My life, my work and my DA are being slowed down desperately by the attempts of big business to divest me of as much cash as they can.  I need a new computer or a miracle with this one.  I can't even get a new graphics card in the UK because they don't exist here for PCI, only for PCIe onwards.  To convert this computer to PCIe  etc. would mean a new motherboard.  Please be patient with me.  I intend to sort this out.  I know it's old.  I just don't like wasting a good computer just to line the pockets of rich capitalists.  I'm a moderate capitalist myself and believe in R&D and investment for profit, pay and progress (without detriment to the environment and to people), but I hate parasites and carefully and deliberately planned built-in obsolescence into expensive products. 

Love to you all.
