It's much better than the EVO. Better mounting system, quieter fan, lower overall system temp under load and at idle, looks better and is better general quality.
Are you planning to add a second GPU card, because you absolutely don't need a 1000w G2 PSU for that system. The EVGA G2 750 or 850 would both be plenty, even factoring in overclocking both the CPU and GPU card, and is much cheaper. All tolled you only really need about a 750w unit and that's factoring in an extra 100w already for overhead. If you think you'll be adding a second card later then the 1000w unit makes sense, otherwise, it doesn't.
