Coming from a person who builds computers for a living, I know that 99% of the drivers out there are free. If you're buying from a big name like nVidia, Logitech, Microsoft, etc. the drivers will always be free. So I guess to answer your question, no your drivers will not cost money. However if you wanted to get more power out of your cards, I would look into overclocking, depending on which model card you have you can either overclock them with a program, or you might actually have to send it in to a company that does overclocking. I hope this helps.
