What is the difference between a PCI slot and a PCI express slot? Can I use a PCIe video card with a PCI slot

I want to upgrade to a PCIe video card. However my board has PCI slots. Do I need to get a new board? Should I bother. Since I have a 2.8mhz right now going to a new board might not be a bad thing... Any help or advice would be great.|||No, pci-e is newer and faster.|||what?



YOur MB may have PCI slots, but not PCI e 16x slots. IT may have AGP. THe difference between th estandart PCI and 16x i sthat 16x is used for GFX's and is faster|||The following link should adequately answer your questions regarding PCI vis-a-vis PCI Express -

A PCLe card is incompatible with a PCI slot.



Does your existing box fulfill your computing needs -- if the answer is yes then don't waste your hard earned dough.A faster PCLe card is a necessity if you are a hardcore gamer & you like all the eye candy.



Stave off fresh purchases until the hardware market settles down a bit -- with new chips & chipsets due to hit the market future-proofing your investment becomes absolutely necessary.Remember Vista will have a tough minimum hardware requirement -- so plan carefully.



Hope this helps.|||no because pcie is faster and i think the pcie cards are smaller|||The current PCI standard allows for a 32-bit bus that has a maximum throughput of 133MB/s. This133MB/s of bandwidth must be shared between all of the PCI peripherals. Graphics quickly outstripped all of the other components in the system. To alleviate this, the AGP interface was developed to give a dedicated channel to the graphics. But now gigabit Ethernet interfaces and UltraATA/133 and SerialATA devices are quickly catching up to this 133MB/s limit.



This is where the PCI Express system is designed to alleviate problems. In its current proposed first revision, the system has the capability of allowing a single interface adapter to receive as much as 16GB/s of data bandwidth. This is achieved through the movement away from the old parallel models to the higher speed serial interconnects. Future revisions expect to have even higher bandwidth
