It depends on what I have to upgrade. This year I upgraded a 2 year old board, CPU, DVD, PSU and case. I guess I spent $600 in a few weeks. What eats me up are the extras that I don't keep track of, like keyboards, mice, external HD enclosures, spare drives, headphones, speakers, media, and a game now and then. My next splurge will be for a new video card and more external storage, so this year I will spend a grand easy. I should be set for a while so next year I expect it to be much less.
