I'm considering getting a 165 off of ebay...
how much of a performance increase will I see between my x2 OC'd to ~2.4GHz vs. the Opty OC'd at say 2.7-2.9GHz

it looks like the opty has 2 x 1mb L2 cache while the 3800+ has 1x 1mb cache... besides that they look pretty similar. I think i remember something back in the day that opty's are made w/ better material or are higher quality because they are intended of servers.

is there a stepping on the 165 that is more preferable for better OC'ing?

Thanks
 
they are binned higher because they are server chips. and i think you can take a 165 over 3ghz. i could be wrong though. I think you'll see a huge performance increase over the 3800
 
Ive had a few optys here are the best steppings that are capable of 3.0ghz-
CCB1E 0550VPMW
CCBWE 0550UPMW (Some are crappy actually)
CCB1E 0605XPMW
CCB1E 0606VPMW
CCB1E 0608MPMW
CCB1E 0609FPAW
CCB1E 0609FPMW
CCBBE 0610DPMW
CCBBE 0615EPMW
CCBBE 0617FPMW

AVOID THESE, THEY ONLY GET TO ABOUT 2.7-

CCBWE 0534SPMW
CCBWE 0543TPMW
CCBWE 0546MPMW
CCBWE 0551 (Any packing code) (2.7-2.75ghz 1.55v)
CCBWE 0602 (Any packing code)
CCBWE 0607 (Any packing code) (2.65ghz 1.55v)

if its not on that list then its a newer stepping and will only hit about 2.5 which my last opty was, it waorked great, but i only could get it to 2.5
 
nice, thanks hmammen. thats what i needed

is the "CCBBE 0615DPMW"
