FOR YOUR INFO:

Keep in mind you power supply when upgrading your video cards. The higher-end cards require ATX power supplies north of 450 Watts.

E.G., I installed an older PowerColor (ATI Radeon) X800 256MByte PCI-Express card and found the power supply on my brand new HP M7860n, Core2 Duo, system only had a 300 Watt powersupply. I had to replace it with a 450 Watt supply.

Even though this card is relatively old compared to what's available today it is still a high-end game card and better than most of today's low-budget game cards; it easily managed RealFlight G3.5.
