I've recently spent 1150 € on an all-new rig (based on an i5-3570 and a GTX670), but it wouldn't exactly be fair to attribute that cost to PS2 only. My old machine is 3.5 years old and doesn't really run some of my other games as smoothly as I'd like (PS1, Global Agenda, Natural Selection 2 Beta). It was just time for an upgrade anyway. PS2 only affected my timing for that a little bit.
