Is this is good gaming laptop? Could it run Day Z Standalone?

First, before analyzing, wrong store 90% of the time for gaming towers.
Should be at newegg.com, or custom at cyberpowerpc.com.

TGM1293D - A4-5300 is a low end APU released in 2012. Benchmark of CPU 2017

HD 7480D graphics is part of the CPU.

This $300 Lenovo laptop at Bestbuy has 2 less GB ram and a smaller HDD, but includes LCD, Battery and is 32% stronger at gaming and 25% stronger CPU. Although not upgradable, you get the idea.

Will not look up performance of the first one by gaming because it performs like a low budget laptop.

At $680, very nice i5-4690K, standard 8GB/1TB, and a GT 730, which is below entry level gaming. May be pretty, but an overpriced to performance $60 graphics card is not enough, even though it runs the game medium to high settings. Looking in the box, it appears to be a mini-ITX motherboard normally in a small system, and a generic power supply. If you swapped out the GT 730 for a GTX 750 or 750 TI that does not need a 6pin pcie connect, THEN you have a good PC,

$72 after rebate, minus what you sell the used GT 730 for, that never should have been in the system.

If you do not wish to build a high quality system on your own out of the 8 parts it takes, will browse Newegg.com for under $700. Newegg collects sales tax in IN, TN, NJ, CA

You could take this OPEN BOX i5/8GB/1TB Lenovo, pop in the GTX 750 for $72, and for $519 have a gaming pc that just looks cheap.

Puts you at recommended graphics and plenty of CPU+Ram, so 35-40fps ultra preset 1080p is the standard of "recommended". It would play all games, and just a matter of settings and frame rate

$586 Console that you can use USB to add Keyboard, Mouse, etc.

It can use a 2nd 4GB card and hopefully has an open slot, and CPU is upgradable into i3's and i5's, but the R9 270X is quite impressive at the system price.
Should be around 60fps ultra on DAYZ Standalone.

At $573 and $615 are complete systems with good computer cases.
AMD FX-8320 (3.5GHz) - An 8 core is supposed to improve with DirectX12 in gaming, but in non-gaming is like an Intel i7.
4GB DDR3 | 500GB HDD << Can use another 4GB RAM for $25 and live with the smaller HDD
Nvidia Geforce GTX 750 1GB << This is as the $72 card above
or,
AMD FX-Series FX-4350 (4.20GHz) - Adequate quad core for DAYZ, but a bit shy in new games
8GB DDR3 1TB HDD 128GB SSD << Nice to include the SSD and should be a fast boot and place for DAYZ
Windows 8.1 64-Bit
AMD Radeon R7 250X << is 35% below the GTX 750.

$777 plus some shipping and tax in a build your own is an impressive system, based on a GTX 960.

It can be cut in price by removing and downgrading parts.
Look for build videos and decide if you could build one

You would google GTX 960 gaming performance.
$830 systems are similar at Newegg, but with some lower quality parts and some missing
as Newegg item #N82E16883230058 and N82E16883230031
