Can run Game?

[Annie]

yes,but GamingZone from youtube have low pc,intel i3 2105,4gb ram,gt 710,and runing good games,for the system req.

We're not running normal PC games, we're emulating games.
Those specs are garbage, the GPU won't even support Vulkan to start with.
Plus, those are desktop specs, not laptop specs. If you want desktop stuff, get a haswell or higher i5/i7 CPU and a graphics card that's not an integrated with Vulkan support.

Stay away from Intel integrated graphics such as "Intel HD Graphics". Seriously. The drivers are a huge mess.
If you want to get a laptop, get a quad-core CPU as minimum with some GPU that supports Vulkan. GPU power doesn't matter, but you need a powerful CPU.

I recommend a laptop with i7-6700HQ / i7-7700HQ / i7-4720HQ

now is not good time to buy a gpu cause of mining?

Mining Etherium recently turned unprofitable, and even when it was under the spotlight, it was affecting mostly AMD cards' stock only.
Depending on where you live, there may be legislation set in place to prevent prices from rising in situations like these. Which is what happens here in Europe.
