If you're building or buying a system to do light photo editing and HD video editing - no gaming - where are your dollars best spent? SSD? A ton (16GB or more) of RAM? Best possible CPU? Graphics card? Assuming a typical $1000-ish budget and needing a PSU; OS; and Mobo as well. It seems like even "experts" disagree about what is a need vs a preference, and how much bang for your buck various expenditures actually provide. Confusing... Thanks for any advice!
