Do I need a CPU upgrade to improve online gaming performance?

I used to constantly catch my son playing Fortnite on my PC which I strictly forbid. When I asked him why he won't play on the PC I build for him he told me there is too much lag in the graphics when playing Fortnite (YouTube videos play just fine).

The PC I built for him in 2013 has an LGA1155 Dual Core i3-2105 3.1 GHz Sandy Bridge processor. In an attempt to improve the performance of his PC I decided to add a video card a few months ago. I purchased a highly rated but reasonably priced EVGA GTX1050 TiSC 4GB DDR5 gaming card. This provided some notable improvement but it was still not enough to keep him off of my PC.

This week I decided to take the next step and order a new CPU (still an LGA 1155 chipset so I wouldn't have to replace the perfectly fine MoBo). I ordered a Quad Core i7-3770 Ivy Bridge 3.4GHz that should arrive next week.

My question is....upon swapping the CPUs should I expect to see a dramatic performance improvement? Is going from a Dual Core i3 to a Quad Core i7 the right approach? Or does this sound like a network lag issue his PC is experiencing? My PC is directly wired to the Gigabit switch that connects to my router. His PC is in the basement and is an additional Gigabit switch away from the router.

By the way, for what it's worth my PC (the one I forbid him to play on) is one year newer (built in 2014) and has an LGA 1150 Quad Core i7-4770 Haswell Bridge 3.4 GHz CPU and runs with an Asus GTX 660 DDR3 2400 graphics card.

Any advice would be appreciated. Thanks!

One additional question....when swapping out CPUs do I need to reinstall the OS? I've never done just a CPU swap-out. I've swapped out memory modules, HDDs, SDDs, video cards and other peripherals but never a CPU.
 
Solution
So, the I3 2105, is possibly bottle-necking the 1050ti in some games. Min specs for Fortnight list an I5, so yes, your son might be experiencing lag, or rather the dual core CPU maxing out in game. The I7 upgrade would be huge. An make the experience in general much smoother, and with an increase further in FPS (Due to IPC increase from generation to generation, plus the I7's higher base clock and turbo boost) IMO, yes, the right approach.

You shouldn't have to do an OS re-install, but you could do a BIOS upgrade to ensure compatibility before putting in the new CPU, and then a BIOS reset/CMOS reset to ensure there are no glitches when you install the new CPU.

Remember also to ensure you have a cooler capable of cooling the new 4c/8t...

Remember also to ensure you have a cooler capable of cooling the new 4c/8t CPU, and that you use new thermal paste when putting in the appropriate cooler. Very important.

Also, check the mobo CPU list to make sure it does take the newer I7.

Fortnite is not a demanding game and your i3 meets the minimum specs. Moving up to a 3770 wont hurt, but there maybe some underlying issue. Could be thermal throttling on the CPU. Changing the thermal paste may be all you need to do. But since you already ordered the 3770, I would not worry too much about it. The 3770 is a big jump from the i3 and will perform much better in games that use more threads.

As for the OS, no you wont need to reinstall the OS, but you may need to update the bios on the motherboard with the i3 first. Then the 3770 will just be plug and play.

you can just swap the cpu out but do check the bios you may need to update it. you will see a big improvement in gaming from the i3 to a i7.
you say it is on a gigabyte switch if you still have lag test the computer striate from the router

Seems like the consensus so far is I am doing the right thing. I will be sure to update the BIOS before installing the new CPU. BTW, I plan on installing the cooling fan that comes with the CPU as I am not OC'ing or anything like that. There should be no issue with that, right? Why else would the fan come with the CPU, right?

the stock cooler will work fine just have good airflow in the case and it will be ok
