I recently bought a TNT2 M64 that would freeze after running Windows for about ten minutes.. I took it back and used some of the money to buy a 3D Prophet II MX (GeForce2 MX) and it did the exact same thing (I'm thinking it might be a problem with the nVidia chips on my motherboard or something). I really can't dish out any more more, and since both the ATI Radeon and the Voodoo4 4500 are $149 at Fry's Electronics, I need to pick which one I want to get.. Which one performs better?
