GTX 680 4GB good enough for 4K at "normal" settings?

Hi,

I usually play relatively old games, when they're on a significant sale.

I have placed an order on a 4K TV yesterday, which supports 4K @ 60hz @ chrome 4:2:2.
The reason I mention the chroma support is because the GTX 680 doesn't have an HDMI 2.0 out, which is the only way to output 4K @ 60hz to this TV. It doesn't have a DisplayPort.

However, the GTX 680 4GB has a DisplayPort out, and there's an adapter that converts DisplayPort to HDMI with support for up to 4K @ 60hz @ 4:2:2 (not 4:4:4). That's exactly what my TV needs.

So, that in my opinion negates the need to get an HDMI 2.0 equipped GPU (GTX 950 or better).
That opens up a lot of options in the used market, and I found a good deal on a 4GB 680 card.

Question is, how well will it run games at 4K? I looked at a benchmark of VRAM use which shows that, at 4K, most games take around 2-3 GB VRAM, and some like GTA V actually use 4.3 GB, so I'll have to settle in the texture department.

But VRAM isn't everything of course, and it's hard to find reviews about older cards in regards to 4K gaming.

My CPU is an i5 4570S. 8GB RAM.

Here's a link for the games I currently have installed on Steam, for reference:

Thank you!

 
The problem with older games is they usually dont support 4k resolution. For modern games a single 680 is far too weak, even a 980Ti gives moderate fps unless you go really low on the settings. The 680 is still good for 1080p and modern games but anything higher its going to struggle
 
Horsepower wise the GTX 680 will be a little worse than a GTX 770; that is to say, not cut out for 4K gaming. VRAM is only part of the need when we're talking 2160p resolution, you also need the muscle to run it well. The minimum for okay 4K experience would be a GTX 780Ti (limited on VRAM though so AA will need to be toned down) or GTX 980 on the Nvidia side; on the AMD side an R9 290/290X/390/390X will suffice. Keep in mind that any single card out there to include Titan X is going to require compromising settings at 4K, if you want to max stuff at 60FPS @4k you need SLI or CF unless we're talking old games.
