hello all
i'm currently using 3200+ and wish to upgrade to 4200+ X2 on my 939

anyway, i just spotted this on AMD's website when browsing for drivers
AMD Athlon(tm) 64 X2 Dual Core Processor Driver Version 1.3.2.0053 for Windows XP and Windows Server 2003 (x86 and x64)

what's the difference for this and the dual-core optimizer?
