Setsul#800
I don't understand.
Do you want an APU because the pc will last you a long time or because an APU will last you a long time? Both of these assumptions are false by the way.
Do you want a pc that gets you the best bang for buck or an APU? Because APU means two things: horrible GPU performance and AMD = horrible single threaded performance.
Horrible GPU performance means you'll have to get a discrete GPU anyway, which means getting an APU over a CPU was a waste of money. That means you definitely won't get the best bang for buck.
Horrible single threaded performance means terrible performance in TF2. Terrible performance is quite the opposite of "maximum potential". It also means AMD will not get you the best bang for buck in TF2. In other things it used to, but those times have passed for now (Zen is coming, GET HYPE) and it TF2 it never was the case.
So APU and best bang for buck or as you called it "maximum potential that 400-450 can get me" are mutually exclusive.
Do you need a complete build or are you going to reuse anything?
What about peripherals?
Once I know that I might be able to "give computer help".
oh alright, and to answer you i would just like the most bang for my buck exclusively
and also i dont know alot about these things so a complete build would be preferred.
i also dont really care about the peripherals.
EDIT: WOULD ALSO LIKE TO EMULATE MELEE ON DOLPHIN AS WELL
