Do I need a graphics card for LoL?

[Severfeather]

I would like to know if I need a graphics card for my custom build computer.
This is my build

I Plan on running LoL at high settings and 1920x1080.
The build includes a graphics card but my question is: without the graphics card what fps (about) would I be at and with the graphics card what fps (about) would I be at.
Thanks

Your computer would be non-functional without that video card. The Athlon X4 740k does not have on chip video.

So without 0, with somewhere around 75 - 90 FPS according to Tom's benchmarks from a few years ago.

you dont need a huge gfx card to run lol but you defiantly need 1 to run your pc...

i wouldnt recommend you buy anything less than a hd 7770 or gts 650 assuming the psu you selected can run such cards... it should there both pretty low as for as power requirements go.

Eximo is right, That motherboard has video out connectors, but they only work if you use a processor with an integrated GPU (APU series). So yeah, you need the video card and it will play league just fine at those settings/resolution.
