About a week into its market introduction, EVGA today made its 55nm GeForce GTX 260 graphics cards lineup official. The company also introduced a premium Super-Superclocked (SSC) variant of the said card. While having identical reference clock speeds to those of the 65nm GeForce GTX 260 Core-216 lineup, the new lineup offers higher energy efficiency and improved thermal characteristics.
The SSC variant introduced has clock speeds of 675 MHz (core), 1,458 MHz (shader) and 2,304 MHz (memory). It is backed by the EVGA limited lifetime warranty. EVGA also disclosed the suggested retail prices for the entire lineup (North American region) in its press-release, so you know which prices to buy them at: US $259.99 for the base model (896-P3-1255-AR), $269.99 for the Superclocked model (896-P3-1257-AR) and $289.99 for the SSC model (896-P3-1258-AR).
