Which lenovo laptop would you recommend between this flex 5 and yoga 720?

The flex 5 specs:
i7
NVIDIA GeForce 940MX
1TB HD + 512 ssd
16 gb ram

Yoga 720
i7
NVIDIA geforce Gtx 1050
256 ssd

the yoga is 200 more than the flex.

I'm an engineering student that will be graduating this year and hopefully starting my career right after. Thanks in advance

Added (1). $200 more**

Added (2). the yoga also apparently has a much longer battery life if that helps

Why do games on my laptop run smoother on the second playtrough?

The first time I play games on my laptop they usually lag alot, which means I have to turn the graphical settings down, but after I complete them I can run them on around high to ultra settings at 24-30 fps. Some games I've played: Far Cry 1, 2, 3 Fallout 3, Dead Space 2 and 3 and more. Can anyone explain why It happens because I can't find answers anywhere else. Please explain In detail. Thanks

And by the way laptop specs are here: Intel Celeron N2840 Intel HD Graphics 4GB RAM 64-Bit.

Laptop name and model: Lenovo G50-30 80G0

How do I use grub rescue commands to recover Lubuntu 17.04?

I'm quite a newbie to Linux. A few days ago I used Boot Repair to fix some problems, but it hasn't finished: after the step of removing Grub files, I made my laptop hibernate and intended to continue later (I didn't know that would cause serious damage).

And now, after it woke up from hibernate, despite pressing Ctrl+Alt+Del many times, only Grub-rescue shows up, I can't follow popular solutions from the Internet to locate Grub files because they are completely removed and not replaced. I also can't even enter BIOS settings and Boot options to boot from a Live USB (I think because of hibernating).

This is what I got:

error: file 'boot/grub/i386-pc/normal.mod' not found.
Entering rescue mode…
grub rescue> ls (hd0,1)
(hd0,1): Filesystem is ext2.
grub rescue> setprefix=(hd0,1)/boot/grub
grub rescue> set root=(hd01,1)
grub rescue> insmod normal
error: file '/boot/grub/i386-pc/normal.mod' not found.

I tried to power off, then pressed and holded the power button, then turned it on again but no boot options at all, just the Lenovo splash screen as you can see in the photo.
