This may be a long shot but does anyone have a dual core Turion Socket S1 cpu for sale, or know where to get one for a decent price?

I have an Acer Aspire 5100 BL51 laptop and although it is a couple of years old it still pretty much fits my needs. I am going to spend $150 upgrading the hd to 320gb and ram to 3gb and thought if I can slot a faster processor in it would handle my RAW pics from my DSLR a bit better.

Apparently the bios can handle any Turion Socket S1 chip.

The chip I have at the moment is a AMD Turion 64 X2 TL-50 1.6ghz.
