FFdshow Performance with my First HTPC (Dual-Core Update)

I decided to upgrade my first HTPC’s processor from AMD’s Athlon 64 3500+ to the dual-core 4200+ version. I was hoping to see some significant performance increases especially with DVD upscaling using FFdshow. I was not disappointed as my CPU processing load dropped from 60-70 percent usage to 40-45 percent usage while upscaling a DVD. One core was only used which allowes the other core to process other tasks such recording TV shows or transferring files. In the end, not to bad of a performance increase for a mere $70 upgrade. My ffdshow settings are shown here while my upgraded HTPC specs are shown below:

• AMD’s Athlon 64 4200+ CPU (2.2 GHz, dual-core)
• ATI’s Radeon X800 Pro video card
• Asus A8V Deluxe motherboard
• 512MB DDR400 RAM (x2)
