I purchased this card as an upgrade for my Dell Inspiron 546 with integrated graphics. The card has eliminated a lot of slow downs and hangs with my computer. While it works good for these older computers I would go for something higher end if your computer has been built in the last 3-4 years. This also is a PCIe X16 2.0 card but it works on the older PCIe X16 slots too, just not at it's fastest level. Good buy overall!!
