Photoshop is mostly CPU intensive. The others will rely on the graphics card but the 7950GTX should do well there. The Quadro would be better but the 7950GTX is top of the line so it should still do well in CAD. Don't look at the GeForce Go 8 series as CAD focuses mostly on the OpenGL API rather than DirectX.
As for the quality, ABS in my opinion is one of the highest quality laptop manufacturers if not the highest. They use higher quality components than companies like Dell and Sony which are less likely to have problems later.
Generic is a term often thrown around by many (including myself at times) as being a bad or low quality component, but in actuality a generic PC for example is one that uses industry standard third party parts rather than proprietary custom manufactured parts. Generic PCs have a longer lifetime because the parts last longer and there is more upgrade options within the PC.

Go for the T7600, GeForce Go 7950GTX, 2 GB of Corsair RAM, and the Seagate 7200 RPM hard drive. Your CAD programs will need a lot of RAM and a fast CPU.
The highest end GeForce 8 series is currently the 8700GT, but as I said earlier the CAD programs do not put much emphasis on DirectX so much as OpenGL so the 8 series will not provide as much benefit over the 7 series as it would in gaming.
