I'm trying to upgrade my CPU in my A6620f I currently have the E5200 dual core in it but I wanted to upgrade to the Q9550 I have an Antec VP450 PSU and I'm also running a GTX 550ti in there what I was wondering was can I run the Q9550 with that card on my VP450 or would I need to upgrade my PSU? oh I'm running 64bit Vista not sure if that matters or not.
