While you can always upgrade to even more power, the system you have should run CS6 fine. Once you've had it a while you'll know if there are any bottlenecks you need to fix.
If there was one thing - it would be more ram.
thx for the fast answere
If you want top know what different hardware can do, after downloading and installing CS6, go to http://www.ppbm5.com, follow the instructions and post your results. Then, narrow down the search of the results to just CS6 users.
You will then know how your results compare to other people's results, and you will see which hardware performs the best. If you find that you can do something in 700 seconds that other people can do in 154 seconds, then you can make your decision. If you decide you can only afford to go from 700 to 500, then you have to decide if it is worth the cost. If you can afford to go from 700 seconds to 154 seconds, then by all means, upgrade.
If you do want to upgrade, I can highly recommend reading through the hardware forum here, and look for posts by ECBowen. Eric was extremely helpful guiding my decisions. In fact, I ended up buying my system from him (ADK). Trust is earned, and Eric has done the work to earn his. I am quite happy with my PC's performance.
With this system.
Windows 7 pro
Core I7 980 6 core
GTX 480 1gb
Raid-1 2x 1TB mirrored system drive
2TB media drive
While rendering the system eats all of the memory, so I assume 16, 24, or 32gb would help.
The 1gb gtx 480 runs out memory occasionally when running graphics over 3K pixels, while we run a gtx 560 2gb on our CS6 system and it holds up better.
Moved to hardware forum
Just FYI, I see my Premiere Pro memory usage exceed 20G of my 32G on a pretty regular basis.
