I suggest waiting to be more sure of Titan's placement, but current benches seem to show it not having enough gaming performance to justify its price unless you are a fan of heavy CUDA performance.
I'd prefer the 7970s not only because of the bundle, but also because of their overclocking headroom and more future-proofed memory configuration. Not only do they have more capacity, but more important, they have the bandwidth to effectively use it, unlike the 4GB models of Nvidia's GTX 670 and GTX 680.
However, unless you already have a decent Nvidia card and a spare PCIe slot and power cables for it, the 7970s would be incapable of GPU-accepted PhysX. That you brought up one of the only games where it matters seems to imply that this would bother you. If that assumes implication is correct, then two GTX 670s would be the best course of action assuming that Titan doesn't turn out any better than I expect it to. If that assumed implication is wrong, then I recommend that you go for the 7970s without a second thought unless you'd rather spend less and get 7950s.
