In October 2001 I upgraded to a Geforce 2 MX card. 64 MEG of RAM !!!!! - that's what my whole PC ran on until very recently!
Not being the latest and greatest it set me back only about AUD $109 (USD $55.00). At that time the Geforce 3 was the flagship retailing for ~ USD $500.00 (AUD $1,000.00.). Which in my opinion is a fair slug for a video card - you can get a whole AMD 950 system for less than that.
