The question I have is on the power supply. I thought I needed 850w for this video card?

Also, should I be considering a video care with 6 mb ram?

Just a thought... If you want to save several hundred bucks, pick the Vanquish level 4.   You'll get a faster video card, but an i5 vs i7 CPU with hyperthreading. Faster for gaming but the photo work might perform a bit better with Hyperthreading, depending what you do.
