So what happens when you take one of the most powerful GPUs of the 2010s… and pair it with a CPU from the late 1990s? This time, we’re flipping the script — running a GTX 980 on a Pentium III system using a PCIe‑to‑PCI adapter (using PLX8112 bridge chip) on a motherboard from the Windows 98 era.

You’ve seen me run retro GPUs on modern platforms — but now we’re doing the reverse: pushing a modern card to its absolute limit (or beyond it) on legacy hardware. Can a PCI slot even handle this beast of a GPU? And just how bad is the performance when you’re bottlenecked by a 133 MB/s bus?

Build #1 – Failed Attempt (Super Socket 7)
CPU: AMD K6‑2 @ 500 MHz
Motherboard: EPoX MVP3‑G2 (ATX, VIA chipset, Super Socket 7)
GPU (tested): Nvidia 7900 GS (PCIe, single‑slot)
OS: Windows 98 and Windows XP
Issue: GPU drivers failed due to BIOS/bridge chip incompatibility

Build #2 – Socket 370 CPU: Intel Pentium III Coppermine @ 866 MHz
Motherboard: Socket 370 DFI board with Intel i815 chipset (2000)
GPU: GTX 280 / Nvidia GTX 980 (PCIe)
OS: Windows XP
3D Benchmark: 3DMark 2001 SE ~ 6700 points. Spoiler: It’s terrible for a GTX 980… but shockingly better than anything from 2001.
