Check the power supply requirements of the card against the computer's power supply, and check to make sure the computer has an expansion slot that matches the card - AGP, or PCI Express.

Reply:You would definitely have to do more research than rely on the information from the price tag.





Many lower end computer, to cut costs, will leave out the 16x PCI-x port. The best place to look would probably be online. The only other place I can think to check this out is the computer box itself. Look for something along the lines of graphics port or video card upgradeable or something else along those lines.

Good luck!
Reply:Why don't you come back with a new thread, and tell us what computers at Wally World, you're looking at, and what you expect out of the graphics card? Is it for gamin'? Better go for a computer with plenty of processor power/speed, and it should have at least a PCI-Express x16 slot,and a 400+ watt power supply minimum. Walk through the gamin' isle, pick up some games you'd like to run. Look at the end of the carton for system requirements. Match these to the prospective computer you're looking at.
Reply:In addition to the first post, check to see if you have a low-profile desktop, or standard. What operating system you have (Some wal-marts sell Linux based desktops) and most importantly: How much you want to spend, and what you want to do with your card. Most desktops sold at wal-mart are low-end systems. They won't be great for gaming, so buying a high end game card would be a waste of money, and might even cost more then the entire system alone.
