I have an older PC(six years/Compaq) with the specs listed below. I would like to upgrade my video card but not sure what to purchase? Their is an online racing game I want to buy and the minimum suggested graphics card is the Radeon 9600, but the desired card is a Radeon x1900GT or a Geoforce 8600 GT. Just not sure what card will physically fit into my system and what's compatible with my current computer. Thanks in advance for your help!
Pentium 4, 2.0GHZ
512MB, 120GB hard drive ATI Radeon 9000(64MB)
If it is 6 years old, it may not have a PCI-Express slot on the motherboard. If you can give us a motherboard model number, we would be able to tell you if it did. Also, use a power supply calculator such as this: http://extreme.outervision.com/psucalculatorlite.jsp to calculate if your power supply is powerful enough to run a newer card.
