The weather's cooling down a little, and as I haven't contributed a work unit since January 30th of this year, I guess it's about time I started the heating system back up.
As my F@H client is running on a 1.6 GHz Duron, I doubt it'll make much difference, but I have a question anyway.  The motherboard is a 
Gigabyte 7NF-RZ.  Availability of Socket A CPUs seems to be dwindling, so I'm wondering if my last chance for picking up a faster CPU is rapidly approaching (if it hasn't already passed).  Do I have any options?
I notice Newegg is selling a 1.83 GHz Sempron, and that looks to be the fastest Slot A CPU they've got.  Would it make much difference from a 1.6 GHz Duron?
