Hi guys,

Don't have a whole lot of know how on computers but I've picked up a rig and looking to upgrade the graphics card as it's falling behind. Will this handle 4k gaming? as I've purchased a 4k monitor as I do a lot of vidoe editing with it - hoping to play some assassins creed origins. What would be a suitable graphic card that would fit? - I'm looking to spend about £200.

Intel i7 3770K 3.5GHz 6MB Cache LGA 1155
Corsair H105 Liquid cooling
Gigabyte Windforce Radeon R9 280X (3072 MB GDDR5)
ROG ASUS maximus V gene intel Z77 motherboard
Avexir Blitz 1.1 gaming dragon series 16GB(4x4gb) DDR3 1866Mhz
Corsair HX850 PSU

Cheers,
iMack
 
If I was to invest £800 give or take for a 1080ti or something similar would it be worth it - won't the other components bottleneck it? Either way I'll need to upgrade it to something as the current one doesn't even have a display port outlet and the monitor input is not hdmi 2.0 so I'm restricted to 30hz refresh rate.
