Why This Build for Diablo IV
Diablo IV manages 126 FPS on Ultra at 1440p here, 18 short of its 144 Hz mark. $1200 is a 120 Hz build in this title, and the gap to 144 Hz closes through Screen Space Reflections, not through a different part in the table above.
One rung above the RX 7800 XT, our Diablo IV data has the RTX 5070 TI at 163 FPS — 37 frames, near 29%, measured at 1440p in this game rather than averaged over a suite. That is the card that takes Diablo IV over 144 Hz, which is the honest reason to want it. Pricing on that SKU moves enough to make it a week-by-week call. $1200 caps graphics at $550 and funds the platform Diablo IV runs on with the remainder.
The isometric camera caps how many entities can ever be on screen, so the load never becomes a CPU problem the way a first-person open world does — instead it becomes overdraw. A Sorcerer clearing a Helltide stacks dozens of additive transparent effect layers plus screen-space reflections over the same pixels, and that is pure fill rate. Diablo IV is GPU-bound, which is why $1200 spends its $550 graphics allocation to the edge on the RX 7800 XT and leaves the Intel Core i5-13400F alone. Moving money the other way costs frames.
The RX 7800 XT across every Diablo IV resolution we hold data for — 1080p: 158 FPS, on Ultra, asking about 8 GB; 1440p: 126 FPS, on Ultra, asking about 11 GB; 4K: 82 FPS, on High, asking about 14 GB. $1200 is quoted at 1440p — the rest of that ladder is what Diablo IV does to the same card at a bigger target, before Screen Space Reflections gives.
On memory, Diablo IV asks for about 11 GB on Ultra at 1440p, against 16 GB on the RX 7800 XT — 5 GB spare, enough that Diablo IV textures are not a decision a $1200 buyer has to make.
Diablo IV ships DLSS, FSR and XeSS. DLSS on Quality is the first lever toward 144 Hz and costs Diablo IV less image quality than Screen Space Reflections does.
