GX-lite? Well 700W is probably not going to be enough for the cards. You're going to want a good 850-900W.

Are you sure? I've just been looking around and seen that on full load 2 6950's use about 430-450 watts.
I have a non overclocked "Phenom II X6 3.3Ghz" if that matters

Well, I'm not sure how reliable your power supply is. I don't know what the GX-Lite is. If its a credibly brand, then it would probably run it, but it also might not.

Its a coolermaster GX Lite 700w, sorry I forgot to add the coolermaster. From what I've heard and read bout it it has 86% efficiency.
Is that importand?

The unit is probably not 86% efficient, as coolermaster defines it as 86-88% efficient at "regular loading" which can be really defined as anything. If it couldn't receive a standard 80+ rating, then coolermasters "regular loading" test is not under normal standard conditions.
