I would like to build a computer capable of producing high quality high res images in photoshop. Talking A1 at 300dpi with multiple layers and effects.
When only focusing on RAM, will I see a performance improvement going 32GB instead of 16GB?
Yes u will. Create 24GB RAMdisc and use it as a scratch.
Its much faster than SSD and and it is easier on the system.
But U will benefit from fast CPU, 2600K is the best choice for the money.
