GIGABYTE introduced a pair of custom-design Radeon R9 390 series graphics cards based on its new 2-slot WindForce 2X cooling solution, the R939WF2-8GD (R9 390) and the R939XWF2-8GD (R9 390X). The two are essentially the company's R9 390 series G1.Gaming products without the factory-overclock. Both cards are identical to their G1.Gaming siblings in every other way, except the branding and box-art. The two cards stick to AMD reference clock speeds, and offer 0 dBA idle cooling. The two should be cheaper than the G1.Gaming products.
