Can I run my computer with two video card 1 pci express x16 and the original pci?

i have two slots of pci, 1 pci x16, and 1 pci x1. now i want to buy a pci x16 for my computer and i don't know if i can have more than one video card at the same time with different sockets, pci and pci x16, and oh yeah is there a socket of 6pin pci on the power source?|||you could do that but you could only use on card a a time. there is really no purpose for that the pci 16 card would basicly run at 16 times the speed of the pci slot. if you have a pci 16 slot there should no reason to use the pci slot for that purpose . the 6pin on your power supply is normaly used in some higher end cards . that pin basicly uses that for the power rather then sucking it from the motherboard. go with the pci 16 . hope this helps|||Sure you can. But realize you can't connect them together. which means you will need at least 2 monitors.|||Yes. I've done it before with an 8800GTS on PCIe x16 and an older cheapo Radeon card on normal PCI. I had three monitors plugged in at the same time, it was awesome. I had a total of three DVI ports and one VGA port so I could have had a fourth monitor if I had one.|||Your board only supports one PCIe video card since it only has one PCIe x16 slot. You can't use a regular PCI slot due to the slot bus speed not being optimized like a PCIe slot and the card won't fit. You will have to check your power supply to see if you have the proper power connector for the video card you wish to buy. Some require two 6 pin connectors, while others only need one. Also, some require a 6+2 pin connector, so be sure to check your power supply. Another thing, make sure your power supply meets the minimum voltage requirements for the card you want to buy as well or you could experience problems.
