Hello, I am asking if the new i3 would perform better then the i5 recommended in another thread for 780 time, or should I upgrade?, this is for 1080p gaming overwatch
For Overwatch the upgrade is not worth it in my opinion. Your i5 should not limit performance that much, and the 780 Ti should not have any trouble with Overwatch.
i5 4570 is 3,2 Ghz and i3 8100 is 3.6 Ghz. You will not gain much from this upgrade. If you upgrade, then go for 6 core like i5 8400 or higher or AMD Ryzen 5. You will need new mobo and DDR4 memory.
For Overwatch the upgrade is not worth it in my opinion. Your i5 should not limit performance that much, and the 780 Ti should not have any trouble with Overwatch.
