If you want a good card, go for a Radeon 9000 PRO, if they have dual monitor support, as it's faster than a Geforce 4 MX. If you already have a Geforce 4 in AGP slot though, then a PCI GF4 MX is the best you're gonna get. You could always look at a Matrox solution if all you want if dual monitor, and no gaming performance, some of the G450/550 were good 2D quality, dual head and PCI afaik.
