Question Upgrade for 4k gaming

Apr 1, 2019
I have recently started looking at upgrading my current system to one that will handle 4k gaming (specifically Cyberpunk 2077 when it releases).
I will be looking to use my Samsung UA43NU7100S TV as the monitor. Current system specs are as follows:

Gigabyte GA-Z77X-UD3H Intel Z77 Ivy Bridge SLI+CrossFire PCI-E3.0
Intel Core i7 3770 Ivy Bridge 3.40Ghz 8MB 95W LGA1155
Intel 520 Series 180GB 2.5" SATA3 6GB/s 25nm SSD (SSDSC2CW180A3K5)
Corsair CMZ8GX3M2A1600C9B Vengeance 2x4GB DDR3-1600 CL9
EVGA nVidia GeForce GTX680 2GB GDDR5 PCI-E3.0 (02G-P4-2680-KR)
Western Digital Caviar Green WD20EARX 2TB 64MB Cache SATA3
Cooler Master Silent Pro Gold 1000w RS-A00-80GA-D3

I know that a newer graphics card and some more ram are must buys but will the other components handle 4K gaming?

Any help would be appreciated

Thanks in advance
Like you said, 16GB is a must and for 4k gaming you are most likely looking at 2080ti, or, at the very least, 2080/1080ti.

Your other components are surprisingly capable even by today's standards. Naturally, you won't be able to achieve maximum possible framerates on CPU-bound titles on lower resolutions, but this is hardly important at 4k, since most games are GPU-bound at this resolution. You will be fine.
