ok, we have an old server here, running NT 4 with pentium pro 200's with 512k cache (its a quad board though). we're upgrading to Win 2000 advanced server and we wanted to bump up the machine a little. what would be better upgrade, putting in two more pentium pros, or using some Pentium Pro overdrive chips on the exsisting cpus? are the PPro overdrives worth it? they are about $100 right now, where a PPro is about $50. thanks guys
