Chip is absolutely the best value per unit of performance I've owned. AMD isn't making a new type of cpu b/c they chips they've been making since the Athlon 64 are AWESOME. What they have WORKS! They don't need to come up with some new line to sell to customers... I can take and x2 64- AMD and put a Pentium anything to SLEEP!
