As shown, the 7970 is more powerful, but also still more expensive. Really depends on what deal you find on one though. I've seen them as low as $280 on Newegg's email promo deals here in the states, and when the new AMD cards release, they may go even lower. Word is the new R280x is going to be a re-branded 7970 GHz Edition for a speculated $300, so we might see standard model 7970s going for $250 by then. If there's any 3 games in their Never Settle free game bundle you want and don't have, it's a no brainer really.
