Can you recommend the Acer G3-710 as a gaming PC?
I currently have an Acer V 15 Nitro laptop
(acer aspire v 15 nitro vn7-571g-53n9)
Under no circumstance. The system is old and wasn't very good even then.
You can forget about research, the version with the i5 6400 has a ridiculous GTX 950 installed.
But isn't that better than the I5 5200u and my 940m in a laptop?
Yes, but it's still outdated and bad hardware.
How much does the PC cost?
300 euro
and I don't want to play high-performance games, Minecraft should be enough, right?
Which model of the Acer G3-710 do you mean exactly? I find several. However, what can be said from the screenshot is that the processor is old and lame. I would not buy it again.
