Clevo W230ST for Photoshop and AutoCAD?

I'm currently a college student and I can see myself using Photoshop cs6 and AutoCAD quite frequently in the future. I will also be gaming frequently. The W230ST in Clevo's line-up seems most suitable for power and portability in my case. This is my first time greatly considering Clevo's, so I have some questions that I've been pondering.

1. I believe the stock cpu 4700mq is sufficient for my needs, but if I downgrade to 4702mq would I suffer considerable performance? I'm leaning toward 4702 because I think it might run cooler. I have been following the W230ST owner's thread and HTWingNut's review threads quite closely. I'm grateful for those posts from everyone for being super informative and helpful . But it seems to me the W230ST still lacks some temperature data for the 4702mq.

2. There's no doubt the 765m performs impressively in gaming for this laptop, but how does it hold against cs6 and autocad?

3. 8gb of ram is more than sufficient for an average user/gamer, but how about for the programs I will be using? Could 16gb worth the upgrade, or is 8gb fine?

That's all the questions I can think of for now. Heat level from the cpu seems to concern me the most currently. I'm willing to go with 4702 if its temperature turns out to be lower than the 4700mq by 5C or so.

Thank you for your responses.
