E5440 - Run Overwatch at Ultra settings?

[microDOS]

I'm building a PC for my friend, and she wants to play Overwatch at Ultra settings, at a 1080p resolution. I acquired a E5440, EP45-UD3L Mobo and 5GB of DDR2 RAM. Then I went and bought myself a $45 Q6600 PC, it was supposed to come with a GTX580 but it came with a 560 instead. So now I'm planning to buy a GTX680, and I'm aware the CPU could be quite a bottleneck, but would it play Overwatch at Ultra paired with my E5440? Or would it not run at 60FPS? Could I overclock my E5440 to play it at 60FPS?

(Apparently E5440 has equal benchmarks to a Q9550, what's the difference?)

Any help would be appreciated.

The Q9550 will consume 15w more than E5400. But the performance will be equal. The Q9550 is core 2 quad lineup CPU and the E5400 is xeon based CPU supporting 2 CPU on same board. And I think with 680 with extra 2 gigs of RAM she can play it at ultra.
