My Dell workstation is on it's last clock cycles and I am leaning toward building a new rig rather than go with the cookie cutter retail buy. Going with an ASUS board (never had a problem with them for previous builds) but don't know which processor to go with, coming from a XEON. Phenon or Core i series? I haven't used an AMD since the early Athlon days, but have been reading really good reviews of their latest processors. Have read good stuff too about the latest Intel stuff. So which route should I go with? Thinking either AM3 or Core i5. thx.
