Need some Expert advice on this configuration

[Tylaris]

Hi guys, I'm thinking of getting a new pc so, basically, I need some advice on how well these components will work together.

Case: Cooler Master K280, MIDI
CPU: Intel Pentium G3258 3.2GHz 3MB Cache, Dual Core
Motherboard: Asus H81I-PLUS Mini ITX LGA1150
Video Card: Sapphire Radeon R7 265, Dual X, 2GB DDR5
Power Supply: 450W Corsair VS450
Memory 8GB RipjawsX DDR3 1600Mhz
Storage: Seagate 1000GB ST1000STDM003, SATA3,64MB Cache.
Don't really need CD/DVD player.

Do I need anything for the internet connection( I use broadband) or is it already integrated in the motherboard? I plan to play video games with this, so how well or can this run some of the latest titles, like Witcher? Top notch graphics are not really priority...I'm more concerned about performance. Are there any better components that I could get for similar price?
Thank you in advance.

if you are using wired internet,then it is already in the motherboard...if you want wifi,you need to buy a usb wifi card.
for witcher 3,it is recomended that you use atleast a gtx 660/radeon 7870....most games will be fine in low-med settings

Thanks...I've been thinking either of getting MSI AMD RADEON R9 270X GAMING 2G ITX? Is there a big difference between these two cards? Will my power supply be enough?

if you want to use a 270x,you need to atleast get a 500w-550w PSU....
