965P S3, 2GB XMS2 5400C4, E6400, WD 160GB, X1300 512mb. Mum just text me after running WD's hdd health monitor/fixer and apparently the system speed is back to what it was. Not sure about the image quality though, I did it with the out of the box drivers first and then upgraded to the latest CCC for that card and there was not the slightest bit of difference.
