I'm in the market for a new graphics card, and am quite keen to go with nVidea, primarily because of Physx support. I've got a budget of up to £300, but I'm more focused on not paying for more power than I'd use. I game on a single screen in 1080p, no 3D for the moment, but I'd like to keep the option open. So here's the question: Would I see any benefit in buying a 670 or a 660 ti over a 660, say over the next 2 years of games. Follow up: Would my current power supply be enough to power any of the three cards in question? My current configuration: CPU: 3.4GHz Intel Core i5-3570K (overclocked to 4.4 Ghz) Motherboard: Asus Maximus V Gene Memory: 8GB 1,600MHz DDR3 CPU Cooler: Arctic Freezer i30 Case: Corsair Carbide 500R PSU: Corsair 650W HX Storage: 2TB Seagate ST32000542AS Barracuda Storage: Crucial CT128M4SSD2BAA 128GB M4 SSD 2.5 inch P.S. I wouldn't mind being alerted to any good deals that might be available on any of the 3 cards.
