Ok well I am starting to get into gaming so i wanted to buy a new graphics card. When i opened my computer to see what kind of slots i have i only have pci slots. There are no pcie slots. What should i do. Should I buy a new motherboard and risk the blue screen? Or is there such thing as a good pci graphic card for gaming? Any help or links would be nice thanksIf you have only PCI slots then your Motherboard is a cheapo and I wouldnt use it for gaming since it was manufactured as a lower end board for regular home or office computing without rendering games as its intent.

Depending on your computer sometimes you can install a new motherboard into the original case and most of the time with lower end machines they are built intently to become throwaways with motherboards specific to the build and not universal.

The other gotcha that I see so many people do is if the case will take the motherboard upgrade the power supply rated for just 240 Watts can not supply the power output needed for the new motherboard that requires 350 watts minimum at which I suggest 400+ Watts. If you are going to run a higher end VIDEO card your wattage requirement could climb into the 600 or 700 watt range to avoid smoking the power supply.

Those who are not up to par with the hardware and requirements and can not afford to take the smoke show risk, I suggest buying a new computer with warranty and a PCIe slot available to take that better video card ( but still make sure the power supply has enough wattage to take the increased GPU power load.) Most computer shops / stores will allow you to open the case of the floor models to look inside and see if it really has a PCIe slot for example without getting it home and realizing OH CRAP this system is a P.O.S lower end STRIPPED model.

Long time ago I BOUGHT a monster HP Pavilion tower for $700 at STAPLES on clearance and got it home to find out that the motherboard didnt have a AGP slot to take a better video card. Instead you saw the silk screen layout with solder plugged in the holes where one could have been, but this was the lower end motherboard build with only PCI slots. Tried to take it back and couldnt because of Clearance purchase and ended up selling it for $300 to buy a better machine with the 8x AGP slot. And at Radio Shack I opened up the computer to confirm that the Compaq Presario 6030 had a 8x AGP slot and that I wasnt going to get robbed againand avoided the clearance computer as well that they had there. This clearance system the HP btw also already had been registered under the previous owner and had games installed on it that didnt require the CD and wouldnt run on the integrated video. Thats how crappy this Pavilion was. Lesson learned ( Be very careful with clearance purchases and its best to spend the extra $100 for a new system, and open it up to make sure you like its innards as well before buying.) Generally they will allow for the floor models to be cracked open, but the new in box systems they wont because it voids the mfr warranty.The PCI Local Bus is common in modern PCs, where it has displaced ISA and VESA Local Bus as the standard expansion bus, and it also appears in many other computer types. Despite the availability of faster interfaces such as PCI-X and PCI Express, conventional PCI remains a very common interface.
So don't feel to unlucky..
