bottleneck always happen, on low-end pc and high-end pc, what matter is whether the bottleneck will hinder you or lowing perfomance, but in your case, this is where you're wrong:
the main advantage of your cpu is that its integrated graphic is decent enough that it doesn't need any discrete GPU, so with adding 1050ti to your rig, u just throw away the only good thing about your CPU...
so, im sorry to say but marginally, it will bottleneck your graphic card
