Hi, I am eagerly awaiting my MP (2.8GHz, 2GB RAM, 8800GT, 500GB HD, 2xSuperDrives, Airport Card), and my 1TB Time Capsule. I have already received an Airport Extreme, an additional 8GB RAM, 2xSamSung SpinPoint F1 (750GB), as well as a Logitech Z5500 speaker system. However, as I have decided to wait for the upgraded ACDs, I will stick to my ViewSonic VP201b for now. Hence, I have a few extra money to spend on upgrading somewhere, and I am wobbling in between: 1) An additional 8GB RAM 2) The Accusys 61000 Raid card (Raid0 on the 2xF1s) The price is about the same (~400USD). I will use the MP for ordinary office work, graphics-, and video editing, as well as playing games in Vista (yes, I am using Vista, and have been doing so very happily the last 20 months). What will give me the most tangible improvement? RAM or Raid?
