Hi! I've recently picked up a dell optiplex 780SSF to play some bare bones games, but as it turned out that was a mistake... so now, i have decided to boost the power a bit. instead of shelling out $500 for a semi-decent pre-built, I'm going to refresh the insides with a GTX750Ti, some cooling, and an Intel Pentium Gold G5600. I am also wondering if the CPU that I have chosen for this build is compatible... Thank you!
