Cool. Just wanting to know where my starting point would be and how much of a step up it would be- I'm attempting to put together a list of parts for a budget PC. I was going to either get a Athlon II 255 or a Athlon II 445.
I had a spare Athlon X2 240 that I used with a $40 motherboard (actually it works well) with some spare DDR 2 memory to revive a old PC (given to me) that died last year (It used socket 939 an Athlon 64 3400+ CPU) and the $40 replacement motherboard was a AM2+ type (Biostar).
I reused the old hard drive with XP Pro on it.I did have to reactivate Windows but it worked (same chipset,IGP and network chip).Right now I am using this very computer to type here.
