I've never had speed problems on any of the systems I've used Project64. The only problem I've had is with sound popping.
As far as speed goes, every game I have ever tried on any system I've owned has run at full speed.
I ran it on a Celeron 566 (Coppermine) with 128MB of RAM and a 32MB GeForce2 MX (PCI), with a Sound Blaster Live! 5.1 and it ran flawlessly.
Next system was a Celeron 1.1GHz (Coppermine) with 256MB of RAM and a 64MB GeForce4 MX440(PCI) and a Live! 5.1 and it ran flawlessly too.
Now I'm running an AthlonXP 2800+ (Barton) with 512MB of RAM, a Radeon 9250 128MB (AGP obviously) and a Chaintech AV-710 soundcard configured for bit-perfect music playback and it runs with relatively low CPU use. ZSNES uses more CPU time than Project64!
On my laptop, a Turion64 ML-37 (2GHz), 1GB of RAM, an ATI Xpress 200M with 128MB of dedicated (not shared!) memory (PCI-E) and an intergrated soundcard, and it has no problem whatsoever.
I think speed problems have more to do with system configuration than hardware specs, espicially with most PCs from the last 3-4 years. The Athlon64 was released nearly 3 years ago and the AthlonXPs have been around for even longer, and GeForce3s were released in 2001. So system power shouldn't be a problem at all if someone built their system within the last half decade. It's all about how well it's configured.
