Read the manual, search for the card online, or check the connector.
The best PCIe video cards on the market today are the nVidia 285 and 295 series.
AGP PCI Express
Yes, Graphic cards PCIe x16 V2.0 compatible ARE fully compatible with PCIe x16.
pci express (PCIe)
PCI or PCI Express
no. only on a pcie slot. buy a mainboard with such
The now obsolete AGP slot was used solely for video. The current slots used for video, the large x16 PCIe connectors, can also be used for general PCIe expansion cards. Sitting in shelf above my head, I still have some PCI and ISA slot video cards: using a general-purpose expansion slot for video is the standard way, and a dedicated graphics expansion slot was a short-term abberation.
Yes. PCI Graphics Cards are backwards compatible.
PCIe (Peripheral Component Interconnect Express)
Unless it's a very old computer, your graphics card will be either PCIe (PCI Express) or AGP, and if it was bought within the last... Say, four and a half years, it will definitely be a PCIe setup for graphics with your other component cards running on a PCI bus. If it was a gaming computer sold post-2003ish it will also have a PCIe bus.
No I don't think so. PCI-X is older than AGP which is older than PCIe
As long as it has a PCI or PCIe bus on the board.
