|I was using an nForce4-based 939 board as my main computer not too long ago. The NF4 is a PCIe 1.0a chipset, so it is a little picky. You’ll have better luck with Nvidia cards. Here's what I tested on my Asus A8N32-SLI Deluxe board:|
-GeForce GTX 460 worked (as did earlier GeForces).
-Radeon HD 5750 wouldn’t even start. The fans would spin, but no POST. The card works; I’m currently using it with an even older i915 based Pentium M board.
-Radeon HD 4890: troublesome. The card worked in 2D mode, but locked up in 3D mode. This card worked fine when tested on the Pentium M board.
-However, a Radeon HD 4870, which is based on the same core as the 4890, worked on the 939 board.
I haven’t tried anything newer than the GTX460 on the 939 board, but my guess is that any GeForce 500 series card would also work. Avoid the 600 series; they’re all PCIe 3.0 cards.
