flashed motherboard atx
whats happens if my motherboard is flashed could it make games run slower?
Yes, a GT1030 can run CSGO pretty well, but mostly because it's more CPU-dependent than anything to do with the 1030.
The A6-7400K isn't a strong CPU to begin with, with the benefits (mostly) being the onboard GPU.
By using a discreet GPU (assuming you've connected the display to the GPU and not to the motherboard), all you're doing is not using the onboard GPU.
It doesn't miraculously improve the CPU performance, unfortunately.
What resolution/settings are you playing at? Are you monitoring your CPU/GPU/RAM utilization?
If not, something like HWMonitor can do that for you: https://www.cpuid.com/softwares/hwmonitor.html
While dated, the i7-2600 is a great CPU. Consider the new route though, and factor that in to any pricing consideration you look at.
A new Ryzen3 1200 (while the budget offering, is a strong performer), B350 board to allow you to OC a little + DDR4 costs right around $240

To invest in an older platform, which you'll struggle to find a motherboard replacement for if the used one you buy fails, it has to make sense.
To me, I wouldn't look to spend more than $100 on an i7-2600 + compatible motherboard.
