No, Never pay more for something less in quality. The TT toughpower may be on the reccomended list but Silverstone is Better.
So stick with the Silverstone.
I high reccomend the corsair 620HX though.
And its more than enough for SLI.

Heatspreaders don't do that much actually, if you have good case air flow, properly moniter the RAM voltages and timming Im sure you could reach that Speed. You could also stick a fan on the RAM for added cooling.
