This article covers GIGABYTE グラフィックボード GeForce GTX660 PCI-E 2GB WINDFORCE2X GV-N660OC-2GD.

Overview

The GIGABYTE GV-N660OC-2GD is a mid-range graphics card powered by the NVIDIA GeForce GTX660 GPU. It comes with 2GB of GDDR5 memory on a 192-bit bus, making it suitable for 1080p gaming and multimedia tasks. The core operates at a base clock of 1033MHz and a boost clock of 1098MHz, supported by GIGABYTE's WindForce 2X dual-fan cooling solution for stable thermals. This card features a PCI-Express 3.0 x16 interface and offers connectivity options including two DVI ports, one HDMI, and one DisplayPort. It supports DirectX 11.1 and HDCP, ensuring broad compatibility with modern monitors and content. Power is supplied via a single 6-pin PCIe connector, and a 450W or higher power supply is recommended. First released in 2012, this model is still available through secondhand markets and occasional new-old-stock, making it an accessible option for budget gaming builds or secondary PCs.

Compatibility Guide

The GV-N660OC-2GD uses a PCI-Express 3.0 x16 slot and occupies two expansion slots due to its dual-fan cooler. Its length of approximately 257mm fits most ATX and Micro-ATX cases, but users of compact ITX chassis should verify clearance beforehand. The card requires one 6-pin PCIe power connector; ensure your power supply unit provides this cable or includes an adapter. For optimal stability, a power supply rated at 450W or above is recommended. The card is compatible with any motherboard featuring a PCIe x16 slot, including older models that support PCIe 2.0 (backward compatible).

Product Info

Built on the 28nm GK106 GPU core, the GIGABYTE GV-N660OC-2GD packs 960 CUDA cores, 80 texture units, 24 ROPs, and a memory bandwidth of 144.2 GB/s. Its TDP is rated at 140W, and the WindForce 2X cooler uses two heatpipes and two fans to keep temperatures in check during load. Positioned as a mid-range solution at launch, it now falls into the entry-level category for modern gaming. It is adequate for lightweight esports titles, media playback, and office productivity. Warranty coverage may vary, but new units typically come with a 1-2 year manufacturer warranty.

Best Use Cases

This card is ideal for budget-conscious gamers who primarily play esports titles like "Valorant" or "CS:GO" at 1080p. Its modest power draw makes it a good fit for upgrading older pre-built desktops where the power supply may be limited. Additionally, it works well as a dedicated GPU for a media center PC, providing HDMI output for video streaming and light photo editing. For users building a secondary or backup gaming machine, the card offers a low-cost way to achieve playable frame rates in less demanding games. Its compatibility with PCIe 3.0 ensures it runs smoothly in systems with older chipsets.

Things to Consider

Given its age, the GV-N660OC-2GD is not suitable for modern AAA titles at high settings; the 2GB VRAM may become a bottleneck for texture-heavy games. It also lacks support for DirectX 12 Ultimate and ray tracing, so newer features will not be available. Power efficiency and driver support are adequate, but NVIDIA may eventually move the GTX660 to legacy driver status. When buying used, inspect the cooling fans for wear and noise, and verify that the card has been tested. Despite these limitations, if your needs are modest and your budget is tight, this card offers solid value for entry-level gaming and everyday computing.
