The 2 reasons beyond benchmarks for going with the AMD is 1. The socket LGA 775 is dead for Intel, no new CPUs will be added to the lineup except for some slight changes such as a possible E8700 or a Q9650S for example. On the other hand AM3 CPUs are still being updated with new ones rolling out like the PhenomII x4 965 BE in a few weeks 2. The deals that have been available on newegg for the AMD CPUs have been impressive to say the least, knock $80 off a good motherboard in a combo deal or $125 for a mobo/CPU/GPU and it gives a nice boost to a budget. In terms of benchmarks just Google for a slew of them. If you really want to go Intel, go with the LGA 1366 or wait for the LGA 1156 to come out.
