ZOTAC GeForce GTX 560 Ti AMP! Edition 1 GB
 

ZOTAC's GeForce GTX 560 Ti AMP! Edition is the highest-clocked GTX 560 money can buy at the moment. Its blazing clocks of 950 MHz core and 1100 MHz memory give it a 12% real-life performance advantage over the reference design, which is quite impressive for the $279 it's coming at. With additional overclocking we could reach 998 MHz, and almost broke the 1 GHz barrier!
