I want to purchase a new graphics card for my Asrock Motherboard, I asked Asrock support which brand should work for my mobo. The response was somewhat confusing:

The Motherboard Asrock G41M-VS3 R2.0 has a 16X PCI-Express slot first generation, and works well with this current generation either be ATI or NVidia, do not install a second generation card because it won't be detected.

I have done my research and it is not clear what graphics cards belong to one generation or another.

Your motherboard is a PCI-Express 1.x generation slot, however most 2.0 cards are backwards compatible with 1.x slots. When you are looking around on the net just check to see if it mentions PCI-Express 1.0, or 2.0, and it should work with your motherboard.

If the card says PCI-Express 2.1, 3.0, or 4.0 it will definitely not work with your motherboard, as they are not backwards compatible with 1.x.

newegg.com can filter cards to show only cards that are 2.0 or below.

Thanks for your quick response Scott, I nailed down this card: newegg.com/Product/Product.aspx?Item=14-500-193 According to your answer, this card should work for my PCI-E 1.0 slot. How can I be completely sure? If there's a way know without owning it. –  Gabriel Feb 18 '12 at 22:52
    
It says it is 2.0, so it should be ok. I would double check with the motherboard support people that the motherboard is at least PCI-E 1.0a. It looks like it is from the email, but you may want to double check. –  Scott Chamberlain Feb 18 '12 at 23:54
