Power supply question

[b1NARY73]

I have a antec true blue 350 watt, with two hard drives, a dvdr,dvd player, 4 case fans, and a hungry CPU Fan (Thermaltake extreme volcano 12). My vid card is a 5900XT at the moment, I am uograding to a BFG 6800GT (got in line at chumbo ) IS this power supply two weak? Should I upgrade it to a 400-420?

My Antec True 320W has run my P2.4, 2 HDs, DVD & DVD burner, 2 fans, case monitor and 6800 GT just fine. Wasn't the actual requirement only 300W?
