On a single core AMD CPU and the drivers if you look do run the CPU at full tilt.
I returned it for a Nvidia 9500. Much better.
Anyone have any idea why my computer is lagging like *beep* when I put in the new videocard I bought to watch HD movies?? The processor is working at maximum speed and it takes like a minute to open a window. The problem seem hardware related since the system is lagging heavily even during windows reinstallation and startup. I have tried with the correct drivers and also disabled the preexisting onboard ATI graphics (RS480 chipset) via BIOS.
My computer is: http://h18000.www1.hp.com/products/quickspecs/1210?5_na/12105_na.html
Or in short...
Processor: AMD Athlon 64, 1800 MHz (9 x 200) 3000+ (alias Venice S939)
Memory: DDR PC3200 400MHz (4 GB installed)
Motherboard: MSI MS-7050
OS: Windows 7, 64 bit
Power: 400 W (It was 250 at first but I have changed the SFF model to a towermodel with 400W)
Videocard is: Sapphire Radeon HD 4350 512MB DDR2 connected via PCIe x16
Glad for any help I can get!!
