new graphics card...poor frames/crashing?

[Winter12345]

<p>Hello Everyone,</p><p>I recently bought a new ATI Radeon 5870 card to replace my old 9400gt. However, for some odd reason, I have been experiencing a lot of crashing and frame rate issues after installation. I am not sure if this is normal, but I'm getting only 15-20 fps on Extreme Quality in populated areas. I feel that should be much more considering the 5870 is a rather powerful card. What could be causing this? I believe the drivers I installed on the card was 10.6. </p><p>This has not been the only game with this problem...in fact I am unable to even start Starcraft 2 at the moment... :/</p><p>My specs:</p><p>4GB DDR3 1333MHZ</p><p>1GB ATI Radeon HD5870</p><p>AMD Phenom II X4 925 2.8 GHZ</p><p>600W Extreme Cooling Power Supply</p><p>750GB SATA II HD</p>

<p>15-20 fps sounds about right considering the cpu in extreme quality with shadows and stuff.. but make sure you uninstalled your nvidia gfx drivers properly, drivercleaner etc could help.</p><p>and try reinstalling sc2</p>

This would be why it is a good rule of thumb to stick with the same chipset manufacturer. Most brands will interchange without any issues, but I often hear of problems when going from one chipset to another(Radeon to Nvidea and vice versa). I would try rolling the system back, uninstalling the Nvidea drivers and re-installing the 5870 drivers again, or using a 3rd party clean up software.

<p>I have to agree with Riun as I've run in to the same problems myself and with test cases.</p><p>If the issues persist beyond that I'm here all week!</p>
