hi siggmuss,
now i have a pentium 4 , 2.6 and 512 ram, and i feel limited , i cant work very compex patches ..... the salesman told me pentium m is faster than pentium 4 but im not sure
2.6 MHz should let yo do just about anything in PD. you might look into the possibility that your P4 processor is giving you trouble with denormal numbers. If you see any strange leaps in CPU usage, it is probably this denormal bug. It is common for P4 processors with all kinds of audio softs, so I would recommend either an Athlon [which I use with my "Polish laptop", a Shuttle X with Athlon XP processor] or a G4 or G5. These days, I only steer people away from Intel processors if they want to do audio. As others here have mentioned, these new Athlon 64 bits are looking interesting, however there is still not a lot of software which takes advantage of them.
best, d.
