Yeah, it really doesn't take as much as people like to portray to play stuff on 1080p high/ultra. Even people with the "old" i5 2500k will be fine for many more years to come due to the weak hardware inside the consoles which will be used as the lowest common denominator for years to come (no matter if we like that or not, it's just reality)
For my needs tbh if I were building another pc over again, I'd go with the fx 6300, 8gb of cheap ram since speed really doesn't matter for gaming, it's marketing to try and get you to spend more money, and a 750ti and cheap 430w corsair builder psu and some cheap black case. You live and learn though, and I'm just telling you from 1st hand experience OP that the extra money for intel wasn't worth it for me personally for my uses, i.e. the normal user, aka browsing/multitasking online and playing a game at the same time. Maybe it's from a lifetime of playing consoles before I built my pc over 2 years ago, and my continued use of an xbox 360 and ps4, but, as long as the game is 30fps+ to me that's fine while having decent visuals.
If you get trapped into the cycle of "having" to max every little useless setting out, it'll eat your wallet alive.
tbh I'd sell my i5 pc if the value for the parts hadn't plummeted due to bitcoin mining, and pc parts in general just having horrible resale value, then due to scammers online trying to sell stuff >_>
It entirely depends on the users needs, but in short, yes AMD cpu like the fx 6300 and 8320 will age very well, both consoles only use (rather anemic ~1.6ghz) 8 core AMD apu, with an hd7790 level one in the Xbox 1 and an overclocked hd 7850(maybe 7870m lvl gpu supposedly) in the PS4, with 8gb of unified shared ram.
will my 1055t get the best fps in rts or mmo? Hell no....but then again I'm not into those games at ALL, and if I ever do play them it's casually. I'm more into FPS playing online with friends, or other co op stuff, none of which is very demanding, my friends get by on way weaker hardware than mine. One games on an old Athlon x2 64 4000 dual core 2.2ghz cpu, 3gb ram, and a 2gb ddr3 hd 6670, the other has a quad core AMD APU a8 5500 I think, 3.2ghz, and just uses the integrated graphics, with 8gb ram. Some prebuilt HP Desktop from Bestbuy with Beat's Audio built in he swears by lol.
so yes, the 6300 is enough to game/multitask with when paired with a good gpu. Even the 750ti is no slouch, videos are all over youtube showing how it can play games on 1080p at ultra or at the worst high, barring the taxing MSAA, which I turn off on my HD 7950 and HD 7870 pc anyway. AMD ever since the summer I believe, has had their equivalent of Shadowplay anyway in the raptr app.
