Im still kind of new to building pc's so bare with me. i just upgraded my gpu from a geforce gtx 750 ti to a gtx 1050 and im experiencing small lag in almost every game i play. with my old graphics card i wouldn't lag on any of these games so i figure its my cpu because now when i go into task manager while running a game it'll say its using 100% of the cpu when i had my 750 it wouldn't do that so im confused do i need a new cpu? or maybe a new motherboard? or could it be something else?. Here are my specs.
GeForce GTX 1050
AMD Athlon (tm) x4 860k quad processor
8 GB of ram
motherboard model: A68HM-E33 V2 (MS - 7721)

Yes your CPU is bottlenecking, now it may not bottleneck in every game out there, but in games like BF1, BF4 and really any multiplayer game with lots of players you will have the bottleneck. If I were you I would upgrade the CPU and motherboard.

Before I can recommend anything though I would need to know your budget, so if you can upgrade what is your budget? You would need enough for a CPU and MOBO, but if you want a Intel based CPU I would upgrade to DDR4 and get a Skylake CPU. You can also wait for the new Coffee lake CPUs Intel is releasing and see if that would be a option.
Typically the GPU and CPU work in tandem for games. With the GTX 1050 being more powerful than the previous GTX 750ti, it should make the CPU work harder as you've discovered.

The base performance shouldn't have changed too much as you've still got the same CPU. And depending what you're playing, a full load may not be too surprising. (My x4 760k will max out on certain games.)

I would use something like MSI Afterburner to see if there's anything else going on to help investigate the lag. Though I would ask whether you performed a clean installation of drivers to be on the safe side.

Whether you need a new CPU will depend on your expectation of your system and its current performance relative to it. But with your currect specs it means a new build (CPU and motherboard at the very least) as the x4 860k is one of the fastest CPUs for that motherboard.

I wouldn't use Afterburner to tweak anything just yet; my suggestion was to use it to investigate whether there is something going wrong.

Consider monitoring CPU, GPU and RAM usages along with fps and frametimes, and perhaps temperatures. Use AMD Overdrive to monitor the thernal margin of the x4 860k to see if it's a temperature problem with the CPU (a thermal margin above 0 deg C is acceptable on a full load).

The other thing is what processes push the CPU to 100% usage in Task Manager? Is it just the game?

Did you clean install the graphics driver after you uninstalled the old ones?

Those are a few things to consider before spending money to build a new PC anyway.
