max, photoshop, modo, and all the apps i use are 64 bits. Ram is insanely cheap now, go to 32GB if you have a decent budget and you are going to use more than 16GB (i easily eat all my ram). 32GB of DDR 1600mhz cl9 should not be more than 150 euro now (i paid that for my 16GB!!! :) ) The more the better, but don't forget…
