the 448 also overclocks better. so they are literally the same card at the end of the day.
Both the 448 core and the 570 580 core will murder the 2GB Ti 95% of the time at 1080P. Some games are a bit of an exception but they are few, and at 1080P you will be limited by (gpu) processing power anyways.
