Thinking about a possible GPU upgrade

[AMD6415]

I am thinking about upgrading to an ATI 4870x2 now my first question is I have an E8400 @3.74GHz this is fast enough right? and also I'm sure this is fine but I have been reading a lot of power issues with this card, I have this Newegg.com - PC Power & Cooling S75CF 750W EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Power Supplies it will be plenty right?
