If you like that, sure.
There is no correct DPI. Its simply what you like to use.
I personally use 2200, as its fast enough on my deskptop, but also accurate. In game, I typically never have to mess with sensitivity.
Some people, like my friend, play on 800 DPI and turn the in game sensitivity way up.
My other friend plays on 2800 and low in game settings.
DPI is all preference. Some people will list the DPI that pro players may use, this means nothing for you though.
