Can I "overclock" ATI Radeon 9250 to make it DirectX 9 compatible? Is my current graphics card (9250) compatible with DirectX 9? And if it's not too much trouble, what does DirectX 9 require that the 9250 doesn't have. Can 'overclocking' (is that the right word?) get around it? My computer specs are: AMD Athlon64 3000 (1.8Gh) Gigabyte GA-K8NS-939 (mother brd) 1Gb ram 200Gb mem ATi Radeon 9250, 128M (graphics crd) Do i need a new graphics crd?
