Gaming

Frames per second (fps) measure how many images a game shows each second. Higher usually feels smoother.

30 fpsBasic target
60 fpsSmooth target
120 fpsHigh refresh target

These are general guides. Slowdowns and uneven frame timing also affect how a game feels.

Configuration matching & limitations

GamersNexus: Purchased 64 GB / 4 TB sample. Chassis claims transfer separately from performance. Article and June video are one project.

PC Gamer: Same CPU/GPU pair in another chassis with 64 GB DDR5-6400. Stock CPU, dual 240 mm liquid cooling. Target RAM speed and power behavior unverified.

Windows Central: Dell supplied the tested 5090 / 64 GB unit. The 5080 recommendation is not the tested configuration.
