In every aspect the GTX850M wins massively

There you can find the comparison
If I were to pick on the two I would go with ENVY as it has a much better GPU

It's 4GB of vram vs 2GB of VRAM. I pick 4 :D
So I was reading the 'internet' as always today when I came over the C.H.I.P. $9 mini computer that slightly looks like a raspberry pi. It's specs seem good enough but is it really? What do you think? Would the chip $9 pc be a good htpc...
You don't want to play on a 48Hz monitor. Not even on 4k!

Something like that is great!
Run dxdiag
Go to display
What's the name below device?
That's how you find out what GPU you have
Is the monitor connected to the GPU or motherboard?
Did you have a look inside the case? Is there a name or serial number on it?
