well, you answered it yourself.
apple's computers are nowhere near the power of a custom built PC for gaming, especially not the 2012 imac.
keep your current PC for gaming and do everything else on your imac.
even if you got a new apple machine, it will be basically non-upgradable down the road when games become more demanding.
Im an owner of the new 5k imac with radeon pro 580 16gb ram 4.2i7 3tb fusion and this thing works just fine for Gaming On nearly maxed out setting on 2016 and some 2017 titles and the cod WWII runs (98percent of the time) at locked frame rate 60fps with most setting(70-80percent of stuff) on extera or what ever maximum theybhage and 1440p
The Assassins creed origins Runs locked 30fps on high setting and im using thye bootcamp drivers from apple Not bootcampdrivers.com thats why i cant go higher on Origins batman arkham knight Works just fine 1440p maxed out 30fps locked (only one setting is 8x instead of 16x everything else is on the highest) no noticabke throttling
And he 580is On par with the 1060m its somewhat near a 1070m why Underestimate it ?
Its a repected gpu honestly even for gaming
[doublepost=1510241645][/doublepost]Alright man listen Up if there are more important stuff that Gaming on 120fps 4k With a Hevay gaming head set and a gaming mouse and you want thte form factor or the macos this might be a Really Good choice for you
Look,The new imac (to me) is the first time apple actually put a real gpu in their Macs (other than macpros which Have Ok GPUs)
This thing is 5.5teraflops (the top end rmbp with the 560 is only 1.9tflps i guess so dont even consider it for gaming seriously)
So the radeon pro 580 is something in the middle of a nvidia1060 and a1070m and Even if you use Official bootcamp drivers from apple You can play almost any thing on high 1440p (90percent of stuff on max setting 45+fps and 1440p and if you get the bootcampdrivers.com you might even be able to go much higher
This IS a gaming machine i see no throttling
The only issue is that if you choose the fusion drive the Bootcamp is installed on the hdd and its gonna boot slower but for me The gaming performance is Fine
Its your choice Bro
Cause i dont know if you need That 120fps On everything maxed out or not
But i myself Have to tell you one thing :dont waste your time on gaming too much specially dont waste on opting for he highest setting at the rate gpus are getting outdated
There is more to life honestly!
So that being said My recommendation would be :
Sell that Gaming rig of yours and get the top end imac 16.32gb ram i7 4.2ghz pro 580 1tb ssd (and if you really need the 3tb fusion like me go for it but expect it to be slower when booting up in windows and well You know ssds are much more reliable)
And Get a fresh copy of windows 10 installed and do your windows work on that side
And its gonna be fine for heavy gaming on 1440p too
