ComangliajollyfryI kinda have the same goals that wo has with a computer build. Since I don't need peripherals, would this be a good build? I just upgraded the cpu and the video card to make them a little bit more powerful.

If you can afford Intel prices it's well worth it. Beyond that your build is perfectly fine for playing TF2 and never be a problem for a 60Hz/75Hz Monitor.
Though this is true (coming from a phenom ii to haswell i7), its not really worth it unless you have a super big budget, 120hz is a lot more of an improvement imo (not that it'd necessarily be possible in this budget, just a point of reference). But yeah, for this budget I'd definitely say go for amd
