GPU + RAM performance simulator
See the frames before you build the rig.
Choose any graphics card and memory kit, then watch the footage run at the frame rate, resolution and stutter that build would really give you. Two builds, one divider.
Compare two cards in ten seconds
Pick two GPUs, choose a preset, and jump straight into a live side-by-side with each card's matching memory.

What the simulator actually does
It throttles the picture
The footage only updates at the frame rate the build would reach. A card that gets 18 FPS really shows 18 frames a second, with uneven frame pacing.
It scales the resolution
Render resolution from 480p to 4K changes the internal pixel buffer, so low settings look blocky and high settings look clean.
It starves the RAM
Too little memory triggers texture-streaming freezes of 80 to 250 ms, softer textures and a frametime graph that spikes.
