Not so fast there, JCitron! Check out some of these reviews for the GTX 1050 Ti (the slightly faster version of the 1050 with 4Gb of GDDR5):

According to benchmarks I've seen, it outperforms the venerable GTX 770, GTX 960 and the AMD R9 280X. That would slot it into the 7th level of Tom's Hardware's Gaming GPU Hierarchy when that gets updated again.
Not as fast as a new AMD HX 470 though.
So, it won't be a stellar performer (too few CUDA cores) but at a TDP of 75 watts without needing additional power, it could be a great solution for many people with older machines stuck with PSUs less than 450 watts.
