1080p 120hz/144hz VS 2560x1440, which one requires more GPU power?

post #1 of 6
Thread Starter 
I'm thinking about switching my vg248qe to pb278q, i wonder how much hit will my dual gtx 780 take with the higher res?

To elaborate my concern, i'll give an example:

When playing bf4, i can maintain 144hz @ 1080p using dual 780 @ 80% usage.
Now if i use the pb278q, i wonder if can maintain 60hz with 80% GPU usage? Or will it need more or less gpu power?

1440p at 60fps will use more power.

My question involves FPS, i know that if they are both running the same 144 FPS the pb278q will require more gpu power, but the comparison involves 144hz vs 60hz.

I know I just edited my post a few minutes ago tongue.gif 1440p takes a lot of juice.
I remember the moving from 1080p to 1440p the first time took a performance hit badly on a 7970 lol

For example let say you play 140fps on bf4 1080p max sets and use 80% you would get somthing like 58fps-70fps at 1440p at 90%. But its best to ask people that play bf4 at 1440p lol I play bf4 at 1080 wink.gif

Vs 1080p @ 144hz?

There are also 120Hz options at 2560x1440p, if you want the double whammy. thumb.gif

Whether it is the QNIX overclockables, the Overlord Tempest, or the upcoming ASUS ROG PG278Q (the only lightboosted 1440p)

But, that can be out of many gamer budgets to power 1440p successfully at triple digit frame rates.
