GeForce GTX 780 3GB GDDR5

The EVGA Classified ACX card delivers 2304 CUDA cores and 3072MB of GDDR5 memory on a 384-bit interface. It connects through PCI Express 3.0 and supports Microsoft DirectX 12 at feature level 11_0. The base clock runs at 993 MHz with a boost to 1046 MHz. This model is built for enthusiasts who want factory overclocking headroom and G-SYNC compatibility.

Suited for 1080p high-refresh and 1440p entry gaming

Gamers targeting 1080p at high frame rates or 1440p at medium settings will find the 3GB frame buffer adequate for many titles. SLI support allows a second card for additional throughput where profiles exist. Users needing 4K performance, modern ray-traced titles or more than 3GB VRAM should consider newer architectures.

3GB VRAM handles 1080p ultra

The 3072MB GDDR5 pool at 6008 MHz effective provides comfortable headroom for 1080p ultra texture packs and 1440p medium presets. At 4K or with heavy texture mods the 3GB limit becomes a bottleneck, forcing texture streaming or reduced quality. The 384-bit bus helps sustain bandwidth but cannot overcome the capacity ceiling.

Questions about this item

Does my power supply need to provide a 6-pin and an 8-pin PCIe connector for the GTX 780 Classified ACX?

The GTX 780 Classified ACX requires both a 6-pin and an 8-pin PCIe power connector from your power supply to deliver its 993 MHz base clock and 1046 MHz boost clock.

Will the GTX 780 Classified ACX run in a motherboard that only has PCI Express 2.0 slots?

Yes, the card is PCI Express 3.0 compliant and will operate in a PCI Express 2.0 slot at 2.0 speeds without affecting the 384-bit memory interface or 6008 MHz effective memory clock.

How can I confirm the GTX 780 Classified ACX is running at its 1046 MHz boost clock after installation?

Use EVGA Precision X or GPU-Z to monitor the core clock in real time; it should reach 1046 MHz under 3D load while the 2304 CUDA cores process DirectX 12 feature level 11_0 workloads.
