275 is not faster, similar upto 1920, but @ higher AA n 2560 reso, 280 starts to shine, thanks to 512bit memory bus and 1GB frame buffer, 275 is 448bit and 896MB, both have 240SP. U should atleast try for 14.5k, its brand new card + XFX + slight edge over 275. Both have same power consumption @ load, @ idle 275 consumes 15W~ less. 275 stock clocks are 633/1404/1134, 280 is 602/1296/1107, thats why its close to 280 in reviews, otherwise clock to clock 280 better. and both overclock similar also, approx 700 core, 1550 shaders, 1250 memory :lol:
