One has to be careful when choosing a Geforce 4 MX 440 or an ATI 7500. Both of those cards are available in "ubercheap" models, but come equipped with SDRAM rather than DDR, hence their performance is severely limited by their bandwidth. Make sure the cards you are considering come with DDR ram. The Crucial card I mentioned earlier does come with DDR for $51 shipped. If you are considering a Geforce 4 MX 440SE with SDRAM, the old Geforce 2 GTS Pro will outperform it, likewise for the ATI Radeon 7500 with SDRAM.
