photoshop cs6

I am using photoshop cs3 extended but i want to replace it with new version,but i know which is the best version.

Photoshop CS6 Extended is the most expensive version. But it might not be the best for you. If you don't need the forensic analysis features, or the 3D capabilities of Extended then CS6 Standard will do.

i think CS6 is one of the most power full and usefull Photoshop virsion that's why its my fvt.
