Hello and welcome to the forums
5650M is significantly faster than a GT 230M in gaming but both are fine for Autocad,3D max and PS.
These tasks are mostly CPU limited,so make sure you choose a good CPU.
Thanks for the reply. I believe as long as I am not into gaming I 'll go with the NVIDIA, i7 1.6 GHZ processor. While looking for a laptop, I wanted to have a 17" screen, with an ATI radeon the price was reaching $2000 min. A 15" screen with a good graphic (ATI) card is in the range is in the same range as a 17" screen with NVIDIA...you helped me spare around $500 to $600...thanks
