Jim - Re: "Or does any old 3D game benefit?" All software has to be re-written (if it uses the new 3D instructions directly) to make use of these new instructions. If Microsoft incorporates the new 3D instructions in their DirectX/Direct 3D APIs, then existing software that uses DirectX/Direct 3D calls and libraries may benefit from these enhancements without being re-written. If the speed of existing MMX and FPU instructions is improved by AMD - due to pipelining and/or parallel execution, then existing Software will be speeded up due to these circuit enhancements. Paul

Jim , <when is MMX2 coming> You can find the answer to all those questions in the december issue of BYTE mag at your local library . According to that magazine MMX2 is being released in the Katmai PII in late '98-early '99 . Also re does AMD-3D need software , microsoft direct 3D libraries built in to win95 and win NT operating systems interrogate the processor to determine which if any type of extensions are incorporated in the CPU . If it is a non MMX cpu then software emulation is used , whereas the correct extensions are used in the case of an MMX type cpu . The direct3D is a software interface between applications and the hardware (API). However the magazine does say that programmers will no doubt write their own software to further improve the performance of K6-3D etc. hope that helps , Brian
