Hello, hope this reaches you in time to still be of any help!
If you are planning to use any high-end 3D software such as Maya, you will want to have either a gaming card or a workstation card if possible.
Now since you have pointed out that a workstation card is not an option, it leaves you with either the Mobility Radeon or the Intel GMA 950. I would personally go for the Mobility Radeon as it is a gaming card, which Maya unofficially supports.
Your comment on hearing that Maya needs a dedicated graphics card just to run? It’s defiantly not true. At my school, the admin installed Maya PLE on some rather old Dells using P4 2.8 GHz with no HT and of course, Intel graphics! But you do need one if you want to run Maya smoothly and to get the important features working, such as High Quality Rendering for previewing.
A warning though, I still don’t think Maya supports any GeForce cards or chipsets. I could be wrong, they may have added support for them, but last time I checked, they weren’t supported. Of course, you can try and if your lucky it may work, but its not recommended.
Hope all of this helps.
