[LAU] New processor purchase, AMD

I am looking to make a new computer purchase, and have decided I want a 64bit AMD quad core processor. Before one gets to the Opterons which start at about $205, I am looking at these two: (A) AMD Athlon II X4 605e 2.30 GHz Processor - Quad-core, 4000 MHz HT - 2 MB L2 - Socket AM3 PGA-941 - SKU: BA47028 Mfg. Part No: AD605EHDGIBOX Condition: New Price: $124.99 (B) AMD HDZ970FBGMBOX Phenom II X4 970 3.50 GHz Processor - Quad-core - 1 MB L2 - 6 MB L3 - SKU: BA47186 Mfg. Part No: HDZ970FBGMBOX Condition: New Price: $184.99 That is a $60 dollar difference (prices are from mwave). For audio, should I really spend the extra 60 bucks? Thanks; IK
