Do you mean hashrate? Do you have 100MHs on one GPU card? Or do you mean 100 NXS per day with the card? Both statistics seems quite high to me, but I don't own the card so why not.
Or do you have 100 units of this GPU?

Yes over 100 units of this GPU

Oh, wow, lucky you, what a nice hash power you have!

So then it makes sense to solo mine with all your GPUs.
Generally, Nexus GPU solo mining is worth when your total hashrate is higher than 100MHs (which will be no problem at all with your hw).
