Unfortunately Xilinx Virtex chips costs a way more than existing GFX chips do.. So making Gfx using Virtex woudl be not only technically a lot to ask, but also economical suiside..
I don't know, IF it would be possible to use on of those as a replacement to whole machine.. afterall.. it has more CPU power than any Classix Turbo... :-D
