nVidia 860M 4GB vs. 2x ATI 5850 1GB cards

I have the 2GB maxwell version. I will test passmark when i get home

also worth mentioning if talking about the 860M that it's not just one GPU, there are two flavours with fairly different performance, the Maxwell has way fewer but better cores so is faster than the Kepler:

Looks to be a max of about 5/10% difference between the two... Couldn't tell you which one mine is to be honest I never cared enough to properly look. I decided to work on my desktop at work today as well so left the laptop at home.

Just had a dig and think mine may have an 870 in it possibly. Ill have a look and crack out passmark when I get indoors.

Also this may help you decide what you need. It's part of what I used to determine a 970m is roughly equivalent to a 960 desktop.

Instead of posting a new thread I thought I should probably post this subsequent question in here although it might be more of a laptop question.

I've just swapped over for the first time, putting my laptop on my PC monitor to see how this actually works playing games, and it seems that via HDMI I can't set my monitor to run at 120hz. Any idea what might cause this? Could it be graphics card related?

thanks

What resolution is this monitor, and what version of HDMI does your laptop have?

 

[roastbeeef]

It's 1920*1080. Laptop is HDMI 1.4 I think. Actually that might be exactly it, I remember now it needed a dual-link DVI to get it running at 144hz on my desktop PC, although on the laptop it doesn't even give the option to go >60hz in the settings.

Only issue is, the 260X can't do Xfire,

Of course it can.

I read on, you know already

Most likely the iGPU controls the output to the HDMI/DP ports of you laptop, as such will limit your refresh to 60hz even tho the dedicated GPU is doing all the grunt work.
