I am running Win2K and have just got a ATI Radeon 64MB DDR ViVo and it works great for me with the new 7020 drivers and DX8. I am very happy with my new upgrade. i have not had any problems at all with the Radeon, the performance and speed is great, all of y games look awesome in Win2K. I play UT, SOF, Rogue, Nocturne, all work great. i am very pleased and impressed with my new Radeon.
