I ask because my ultrabook with 4GB of RAM and an old i5 runs PS Raw files pretty fine. It's possible that the speed of your HDD is slowing you down - i.e. the bottleneck might be data access as opposed to data processing
Before I drop money on more Ram I thought i'd ask what you guys are using on your computers?
Currently got 4gb but looking at buying another 8 so will have 12gb in total. Will this be enough to speed up lightroom and Sigma photo pro?
SSD?
