I have a PCI-Express x16 while the card I want uses PCI Express 2.1 x16.
Is it possible to upgrade?
OS:Windows 7 Home Premium
Processor: Intel Core 2 Quad CPU Q8200 @ 2.33GHz(4 CPU), 2.3GHz
Graphics Card: ATI Radeon HD 3400 series, PCI-Express x16
Ram: 6 GB
What power supply do you have? The 6870 uses considerably more power than a 3400. But that being said if your PSU meets the specifications listed on the XFX site it should be fine.
the required specifications were
External Power - 6-Pins: 2
Minimum Power Supply Requirement:500 Watt
* There will be an amps on the 12V rail requirement that you should look up in the manual before buying
