Built for 1080p and 1440p gaming

The ASUS STRIX-GTX980-DC2OC-4 is a GeForce GTX 980 graphics card aimed at enthusiasts who want strong frame rates at 1080p and playable performance at 1440p. It uses the NVIDIA GeForce GTX 900 Series architecture with 2048 CUDA cores and a 1279 MHz boost clock. The 4GB 256-bit GDDR5 frame buffer and PCI Express 3.0 interface keep data moving for modern titles. DirectCU II cooling with 0dB fan technology runs silent during light loads.

4GB 256-bit GDDR5 memory decides fit

The single specification that determines whether this card suits your build is the 4GB GDDR5 memory on a 256-bit bus running at an effective 7010 MHz. That capacity and bandwidth ceiling limits texture quality and resolution headroom in newer engines. If your target games or workloads need more than 4GB of video memory, this model will bottleneck before the GPU core does. Check your engine's VRAM usage before buying.

Two power plugs and a dual-slot cooler

Installation requires one 6-pin and one 8-pin PCIe power connector from a supply rated for at least 300 W system draw; the card itself draws up to 165 W. The dual-fan DirectCU II shroud occupies two expansion slots, so verify case width and motherboard spacing before mounting. Common issues are forgetting the second power cable, blocking adjacent slots, or finding the card too long for compact chassis.

Questions about this item

How does the 1279 MHz boost clock behave once the card is installed in a system?

The GPU will run at 1178 MHz base clock and can reach 1279 MHz under load, provided the power limit and temperature stay within the 165 W thermal design power envelope.

What does the PCI Express 3.0 interface cap in practice for this card?

The x16 PCI Express 3.0 link provides up to 16 GB/s bandwidth, which is the maximum throughput the GTX 980 can use for host communication.

What power connectors and case clearance does this card physically need?

It requires one 6-pin and one 8-pin PCIe power connector and occupies two expansion slots with its dual-fan DirectCU II cooler.
