Hi guys I was wondering if the intel 630 graphics would be good enough for CSGO and Gmod at 60 fps on high or medium settings or should I get get a low end graphics card I will be using the intel core i3-7350k
Intel HD graphics are basically comparable to a low end graphics card. You may be able to run it on Medium but probably with 30 FPS only..
EDIT: Look at this benchmark for some reference: https://www.youtube.com/watch?v=CHXv5QJaxwE
So why don't you just buy/build your workstation with the GPU and see how it runs you can always add a GPU later if you don't get the performance you want/need.
