I wan't to buy a new GPU and i found a GTX 295 and a radeon hd 6850. They are both $100 and I wan't to know which one is better. I found that game debate gave the gtx 295 a higher score than the 6850 but the gtx 295 supports only directx 10. I am looking for a gpu that can run Single player open world games like assassins creed, far cry 3, watch dogs etc.
