Personally I wouldn't run the 2 x 7970 on it (though it may be ok). Nothing against the psu (it's a good one), but that is asking a lot of it (especially if it's already a few years old).

Basically you'll want to allow 150 - 200 W for the machine with oc load, 350W per 7970 (with oc and load) and probably 250~w for the 460 with oc and load.

Even if running just the 2 7970 you will either have to down-clock or not run everything at full load or you will be seriously stressing that PSU which means unstable voltage, hotter, reduced life and possibly make it go bang.
