has anyone tested the difference in speed betwween P4 and the AMD chip. I just wondered which would be considered the best to go for speedwise - if you imagine that the same graphic card etc would be used. Is there any real difference and would the intel chip be more compatible - are AMD fully 100 per cent compatible ??
I was thinking of building my own computer - so how about motherboard too?

which amd processor are you thinking of going for?

any athlon 64 outperforms the pentium by far, there is just no competition.

when it comes to athlon xp vs p4, it depends on the CPU. an xp2800+ could easily outperform a p4 2.8Ghz (without HT ?)

the motherboard will depend on what CPU you intend to buy.

P4's arent really worth it these days tbh, but it depends on your main use for the computer.
