What do you recommend I change next? First time building a PC

Look into motherboard sockets, chipsets and other interfaces.
You will not be able to put a Pentium G4560 on that motherboard.

You need an LGA 1151 socket motherboard with a compatible chipset. H110 can do it but requires a bios update, so you'd be better off buying a B250 motherboard.

If you were to upgrade to a Pentium g4560 you would also require DDR4 ram, thats not a recommendation, lga 1151 boards only have ddr4 dimm slots

If youre looking for a CPU upgrade next, youre going to have to look into a new motherboard too. Lga 1156 is pretty outdated at this point and even the high end processors from that time are old as balls.

If you want to save a bit of money on a cpu and motherboard upgrade by not having to buy DDR4 ram, you can go LGA 1150 and still use DDR3, but get something like an i5 4460, which will be a very good processor upgrade for around 100$ used

Okay, thanks a lot. I'll save this.

So basically if you want to get the Pentium g4560 (which would pair very well with your 1050ti)
you will need this:

and this:

alternatively stick with 4gb if youre not doing any really intensive gaming, buy 8gb is recommended

Or if you go LGA 1150
You will want this tried and true motherboard:

and something like an i5 4460 for a decent quadcore, or a Pentium g3258 which is known for being able to overclock, im not sure if you can do it on H81 chipsets though. Otherwise if youre ok with a basic dual core, go with a Pentium G3260, which is a 3.3ghz, pretty basic chip but it served me very well for quite some time

You can get a Xeon X3450 off Ebay for $25. It's half the speed of the g4650 single-threaded, but the same speed multithreaded, and it will work in that motherboard. It's just the server version of the i7 860. (I have one)

X3440's can be had for $18, and you only drop from 2.66GHz to 2.53.. X3430's are $10, but you lose hyperthreading. (They're basically an i5 750)

So up to you whether you want to rip out everything and spend another $180 or so for CPU, mobo, and DDR4, or just put in a Xeon and maybe scrounge craigslist for another stick of DDR3.
