There's a difference between "being capable of" and doing 4k graphics.

Very true. We can barely do 1080p as it is. Look at how many games still upscale. 1080p upscales very well to 4K. You are better off putting that extra power into better effects / shaders / etc than an increase in resolution. I would even be thrilled if you could go 60fps instead of 30fps, but that would also depend on whether the CPU gets boosted too.
