Not sure what specific amount is cheap in your definition, but here
is a summary of all Mac Pro video card options. As you can see, there is only a very limited list and they are not cheap when compared to their PC counterparts. A brief search on eBay seemed to indicate that it's hard to find any card less than $100 no matter how old they are. According to the last post of this link
, you may be able to find a PC version of an ATI X1900, ATI 3870, ATI 4870 that works in your computer assuming the post is reliable. There is no guarantee that it would work but it's cheaper to find a PC version of these cards if flashing is not an option.
