12GB GDDR6X RTX 3080 Ti for high-refresh gaming

This EVGA XC3 Ultra card delivers 12GB of GDDR6X memory on a 384-bit bus with 10240 CUDA cores and a 1725 MHz boost clock. It targets enthusiasts who want 4K gameplay and VR readiness without moving to the newest generation. The triple-fan iCX3 cooler and metal backplate keep thermals in check during long sessions.

Verify 750W PSU and dual 8-pin power before buying

Your power supply must provide at least 750W and two separate 8-pin or 6+2-pin PCIe connectors for the 350W board. The motherboard needs a PCI Express 4.0, 3.0, 2.0 or 1.0 compliant slot. Windows 10 64-bit is the listed supported OS, though newer versions typically work. HDCP 2.3 is supported for protected content playback.

iCX3 triple-fan cooler with ARGB and metal backplate

The iCX3 thermal solution uses three fans and a full-length metal backplate that reinforces the PCB and aids heat dissipation. Adjustable ARGB lighting syncs with EVGA Precision X1 software for per-zone control. Outputs include one HDMI 2.1 and three DisplayPort 1.4a connectors for multi-monitor or high-refresh setups.
