What if I buy everything listed here but not the CPU, and wait for zen to come out and buy that? Would both options get me constant 200+ fps in tf2 and decent fps in overwatch and other new games? I just don't want to have 200+ fps while in tf2 spawn room and drop down to 50ish when in combat, but instead constant 200+.
I wouldn't buy anything until you're ready to buy everything as GPU prices could fall by then. Yes, my 780 easily gets 300fps almost everywhere and much higher in other places (and a 480/1060 are noticeably faster than a 780).
don't get your hopes up because your gonna have a hard time keeping a consistent 200 fps+ in tf2 let alone 144 frames with that build
also there is an rx 480 for 184$ on amazon it is 4gb though and it will be enough for 1080p
No, that build will easily get over 200fps -- it's significantly better than my system and I easily get well over 200fps. And 4gb is enough for 1080p right now, but it won't be long before you're going to NEED more for 1080p in AAA titles, and you're talking an extra $40~ on a near $1000~ build.
Already have a monitor in mind to buy that is 144hz. The rest of what you just said is a blur to me since I have no knowledge in computer parts and stuff. May I ask kindly for you to link me things to buy that can give me constant 200+ fps in tf2 and good constant fps on other games like overwatch?
Again, you don't need 200fps if your monitor can only do 144hz. There's no real benefit to >144fps~ (assuming you have minimums above that as well). And anything above a 970/390 will do the job just fine (and a 480/1060 are around a 980).
