Right back at you. How much are you willing to spend? Are you in the US or somewhere else? Which versions of the software you mentioned do you have - the lastest or older? Is this a hobby or work related? What's the make/model of your power supply & it's specs (wattage & amperages)?
You need to look at the system requirements for your software. You should be able to use a consumer grade 3D gaming card but I believe MAYA recommends a 3D workstation card which is much more expensive.
