[Which Processor is Better?]

Of course faster is...

Pentium 4

2.26 GHz

533 FSB

512 L2 Cache

[Best Peer-to-Peer Software]

I'm using torrent since it's firts days in public.
So torrent is good for new and popular files. The size doesn't matter then.

eDonkey is the best fo older files. I use it, when i can't find torrent links.
Also LDC++ . There is variuos stuff also in pubs.

Anyway the best is Torrent, then eDonkey
