I assembled a PC for cad work and max rendering
My pc specs are
-AMD FX8350
-And all supported items
I need a graphics card so what shud I buy

Nvidia GeForce GTX 660 Ti

or ATI fireGL....  might be happier with your AMD processor.

how much do you want to spend?

Acad can't take advantage of GPU processing  not being a Max user, I have no idea if it can.  that would be something to know before picking out a graphics card
