Egpu Compability

[xipsord]

I have a notebook Vaio VPCSE15FB/b

CPU: i7-2640M
2GPUS ONboad(graphic 3000 and 7400M)

I want to buy:

1080TI (2coolers)
-650W bronze
-adptador for Egpu
(friend is selling it for a good price and I rent a house all incluse(eletricity) )
Would my processor be able to bring all the potential of my 1080ti to mine? I will have compatibily problems? Anyone tried to mine with Egpu’s?
