yes and no.
There will be games that a GTX1050Ti can achieve higher frame rates with a better CPU, and there will be games it won't matter.
I guarantee the simple answer of "there will be no bottleneck" is wrong, especially at 900p, and also for some really demanding games like AotS, a recent Warhammer game and others where it's not just about the draw calls sent to the GPU, but battle calculations etc that really task the CPU hard.
*However, I did several budget builds and the R5-1400 + GTX1050Ti was an excellent choice. Getting a cheaper CPU like a G4600 for example could put money towards other parts but suffered in games that needed more CPU threads (like MMO's) and also the AM4 platform probably will be upgradeable to an 8-core ZEN2 CPU at some point in 2019.
You should OVERCLOCK the R5-1400 as best you can.
You should also use a 2x4GB, or 2x8GB 3000MHz or 3200MHz DDR4 kit setup in Dual Channel.... I did an EXAMPLE BUILD of that->
