As Andrew mentioned, for normal speed with normal resolution encoders it is not going to work. I do not know prices for Pico Systems products (more info here: http://pico-systems.com/motion.html), but prices for Mesa FPGA cards start at 80-90$, which I find affordable. Even more - if You are thining about "headless" PC for realtime tasks and another PC for operator, I am sure that also Pico's solutions would be less cost than second PC. And FPGA card will provide also a lot more I/O pins than You have in 1 or even 2 parports.
