1785 VS 2.4 is it worth it? mabey but i dont think you will see much more speed differance. 600mhz is alot,but i think once you go over 1500mhz it almost takes another 1ghz to see a speed differance.excluding benchies.if you game yes you will then.
you can sell teh 1700 for $40 most likley in classifieds.use that to offset the price.also id look into the 1700B's newegg has.just on the 2100's heels and is only $53
wait? wait for what is really the question? barton is over priced except for the 2500 and its gonna just be a marginal ocer until a few revisions go by,mabey in 8 months the bartons might hit the lower speeds and will be more affordable.or wait a year and mabey score a athlon64.
if you like playing and tinkering non stop like me the 1700 and 2100 is the real deal and affordable.if the pc is a tool, and you set it and forget it dont buy anything and wait.
"edit" btw you have all the good parts to make these chips beg for mercy,dont let a fun oc pass you by.
