so i use my pc for photoshop and vegas pro.
i want to also be able to play games on it.
I tried steam for the first time and would like to be able to run it on my system but as it is now it lags bad, chops and the sound crackles.
I am running a pretty old system but would like to upgrade.
my question is if I upgrade my graphics card and processor can i keep my motherboard?
I'm a total noob to this stuff but don't want to have to keep upgrading pcs every two years.
Processor:intel g2020t
Ram:8gb
64 bit
no idea what motherboard i have.
sorry if I'm clueless.

how do i check for that?
i was looking at the EVGA GeForce GTX 1050 graphics cards and the intel pentium 3.5 dual core lga 1151
I don't know if they are compatible with each other but I was going to go down to micrcenter and ask.
