thats my question.... Is it a better card? how can a 2GB 192 interface with slower clocks beat a 3GB 384 and 900Mhz gpu clock run slower on high res? I mean high res requires memory and bandwidth which the 7950 has and the 660 ti does not
Those cards can't be compared clock for clock, just like AMD and Intel processors can't be compared clock for clock. Architecture is everything.
With that said, the 7900 series destroys the 600 series at high resolution and high detail.
