There's only one version: 1000 DPI that comes with both glossy and non-glossy shells. 800 DPI version isn't produced anymore, not even in Korea.
G1 has low max control speed and is unsuitable for FPS players while MS WMO1.1/IME3.0 have even lower PCS and are mice with more FPS tournament wins than any other sensor. Yeah, makes sense. Also, BMW M3 sucks because Bugatti Veyron is much faster.

Yeah. MX300 (which is basically the same sensor) while limited to 400 DPI has much higher tracking speed (after overclocking USB to get past 8 bit data path).
