Priority and 50% CPU is not the same.
Priority is who gets to use the CPU (first), not how much.
BOINC uses both (Hyperthread on P4) cores at low CPU priority.
If your data bus is clogged by poor (disk,graphics....) I/O, priority won't help much.
Most common is A/V wedged into the chain (where it is not needed), but any file monitoring (auto replication? ) will suck performance.
On this Dell, the Graphics and Disk (the whole PCI bus) seem to be on the same interrupt and the BIOS has no provision to assign INT by slots
other mainboards either split slot INT's (so I just move boards) or allow direct assignment
I surf and convert all the time. Streaming and converting can be hit or miss, so I only run 1 convert job at a time if I want to watch a quality stream.
