1080p GNOME HTPC w/emulators and kodi. Boring but functional default dark Adwaita theme and dash-to-dock + caffeine extensions. A11y "Large Text" on w/scale set to 1.66x via GNOME Tweaks + hack fonts that feel comfortable to read for me.
GPU is an old HD7970 GHz Ed. that I use to offload OpenGL and Vulkan for more intensive emulator sessions. The desktop itself uses the onboard GPU and the dGPU has a ZeroPower feature where it uses almost no power when not being used as an accelerator.
The Haswell generation core CPUs were the first to support AVX2, which is useful in the context of emulators.
With this set up, bottom left is "start menu", top left is "overview/exposé", top right is "window controls" and bottom right is "session controls". Fitt's Law FTW.
