I'm talking hypothetically so I can put it into a different context for future use.
With a 1080 only a 144hz 1080p screen is out of the question since it'll demolish that easily.
A 240Hz 1080p or 144hz 1440p is the only way to get the most out of his graphics card.
There's also an Australian pcpartpicker if you want to use that.
I did offer a 240hz... screen
But 144hz is MORE THAN ENOUGH look at the damn benchmarks of 1080p highest settings witha GTX 1080 FTW
if he gets 1440p at the end of the year his 1440p 144hz will be running at 60 frames....
With 1080p he can future proof his rig. To continue to run past 60FPS on the highest settings.
just look at the 1440p frames on a GTX 1080 FTW
These are last years triple A games. Just think about it... by the end of this year his 1440p will be too much.
Do some research befor answering questions.
All your claims are invalid ass science you do not even explain them or link to proof.
You talk hypothetically about 1060's and 1070s that he doesn't have... you claim 1440p 144 hz is the only way to get the most of his 1080? You have no proof. I do look at the benches he will not even reach 144 frames on a GTX1080 with max setttings1440p. You claim G-sync is a waste? 144hz 1440p that extra hz is a waste.
