Hi, I am looking to crossfire my XFX HD 5770 XXX video card for the first time. All I need to know is how much power is recommended? I have a Corsair 550w power supply at the moment and I'm assuming that it isn't enough, am I correct? I was also hoping if you guys would be able to help me choose a second video card...or would it just be best for me to go with another XFX HD 5770? All suggestions and advice would be appreciated! Thanks in advance!
