I try to buy close to the best there is so I don't have to upgrade my machines that often.
Last I had to buy myself a new motherboard and grafics card, plus new ram cause the new motherboard didn't support my old ram
That came to around 10,000 KR, which is around $1,500, or €1,176 ... I think. Not too sure what the exchange rate is right now.
