Hi guys! I am newbie in pc so I don't why dxdiag only shows 1673 even though 1050ti is 4gb? Is that the only usable memory for 1050ti?

My pc spec
ASUS H81M-K
Intel Core i3 4170 3.7ghz
4GB Kingston HyperX Fury
Corsair VS450

I just recently bought this gpu Palit GTX 1050ti Storm X. So guys what do you think? THANKS!

Solution
click in dxdiag on the "run 64-bit dxdiag" button and have a look again. It´s definitely nothing that bottlenecks. Just not displaying it correctly.
