Good day TPU! I'm in a bit of a dilema. I only have the following 2 video cards to choose from: PowerColor HD7970 Zotac GTX 670 AMP! Edition They're similarly priced and the games I have are SC2, D3, Civ V, and BF3. I'm kind of leaning toward buying the 7970 now 'coz it's currently on stock at the local shop I'm planning to buy from while the 670 would be available in about 2 weeks (I just missed out on the last available card). Which would be a better buy?
