Fast 3D performance Very good 2D quality Decent video capture quality Dual DVI Slightly costlier Massive box Poor TV-out quality Weak overclocking (our sample anyway) This was a very nice card to play with, and shows that the x800XL cards are the sweet spot for ATi cards right now. Asus has done well, but there is nothing included that justifies the price difference between it and similarly equipped cards. If you find this info useful please vote!!!
A PCIe x16 graphics card will not work in a normal PCI slot. PCIe or PCI Express is a new standard in expansion interfaces. PCIe is physically and electronically incompatible with PCI slots.
Only graphics cards are inserted into a PCIe x16 expansion slot.

Yes. PCI Graphics Cards are backwards compatible.
Most likely for dual graphics cards.
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.

I presume that you mean to ask whether a PCIe 3.0 card can be used in a PCIe 2.0 slot on your motherboard. The answer to that question is yes. PCIe standards are all backward-compatible, so do not sweat that. For best performance, however, you would prefer to put a PCIe 3.0 card in the same type of slot.
