I just picked up a Razor Abyssus the reason being is i had a Logitec wireless for about 2yrs. It started jittering on the screen I opted for the Razor brand.
I understanding the DPI and i have set it to 1800 (3500 is just to fast for my liking)
Its also got a 120hz and a 1000hz. i don't know if I should leave it at 120hz or change it nor do i understand what this means. I've done a little research and its for up polling (making it smoother) i dont feel the difference really.
i've also read somewhere that 1000hz it can also use up to lot off CPU usuage and even fry mobo! now this has got me thinking! I know don't belive eveything you hear. but i wanna check with the experts on what settings is best suited for me and my computer. i would like it smoother and i will be using it for RTS style games (SC2)
does it even make a difference in 120hz-1000hz? and if it does does it really stress the CPU that much?
this is my current system (nothing is oC'd) note: i will be cross-firing with another 5850 on the weekend.

Polling rate really doesn't matter for gaming. This matters only for pro level fps gaming where a 1ms input lag in a fps can mean life or death in some cases.
As far a CPU goes, it really doesn't affect it that much, it will use less than 0.05% of the CPU. As far as killing USB ports, yes, that is a EXTREMELY UNLIKELY possibility if the increased polling rate causes the mouse to increase power draw.
