Now this is the only picture I could find with the comparisons. The gold/brown overlay color looks great, but why wouldn't they just tweak the engine to show these colours instead of doing it in photoshop?

Edit: Sorry, just saw that Madskillz already has a similar post. PSU comparison shot is new though... so just rename this thread - "PSU comparison of actual vs Doctored Screenshots"
