Hello guys, i've read alot of issues with with synapse and stuff, so i'll be fast.

I'm receiving a deathadder tomorrow (3.5g) (i've used wmo for 6 years so i never used mouse software or whatever).

So my thing is , i pretend to play at 400 dpi, but, should i install synapse or legacy drivers only? or install legacy first and then synapse? should i keep both? only one? none? can someone enlight me about what's the best? appreciated :)
