if you want a good rig for less cash go with a nicely built AMD, want a true screamer build a high end Intel box, i personally have always had an AMD machine and plan to keep it that way, not to say i dont use some Intel here, i have a P4 HTPC and a P4 Dell Optiplex but they were free/cheap and do the job well
