- Support AMD Socket AM2+/AM2 CPU
- NVIDIA nForce 590

Does it have PCIe 1.0 or 2.0?? I'm having a really hard time finding out if this is specified anywhere.

that board should be PCIe 1.0, only the 7 series nvidia chipsets support PCIe 2.0

Should be 1.0.
Why care anyway? PCI-E 2.0 cards work with 1.0 and difference in performance is hardly noticeable anyway.

Oh really? I thought it was a big difference.

Is there an article you can point me to on this for how much performance increase? Gonna google a bit of course, but I always thought 2.0 >>>> 1.0

In theoretical bandwidth PCIe 2.0 is far better than PCIe 1.x. However, as long as the slot is running in 16x mode (which it will with a single card) there is enough bandwidth even for a HD4870X2. I believe PCIe 2.0 also increases slot power which is good for low mid-range cards so that they don't need power connectors.

Not really, more of a, not yet a card that fully utilizes the slot due to low bandwidth kind of thing.
But if I were you I may invest on a board with 2.0 for it is more futureproof.

It's not a marketing gimmick (although it will be used for such), because future cards will eventually saturate PCIe 1.x. People said the same about AGP 8x (AGP 8x outperformed PCIe 16x originally) but look, it's dead.

So right now, no diff. But there could be in the future. Makes sense. Good info
