Upgrade from what to what? Do you mean upgrade from the 3200+ to the 148? Yeah, there will be some noticed improvement, especially if you can overclock it. Might want to get a different cpu cooler, though.
For new system and if you can manage it, get an Intel E6300 or E6400 for $182 and $221 or so, respectively.
Can anyone give me an indication if this upgrade (ONLY performance wise ) would be worth it ? also any positives or negatives concerning this comapison would be appreciated .
Why on earth should someone seeking performance compare two single cores. WAKE UP! If you want to upgrade a 939 get an Opty 165 or 170 or X2 4200. I have a 3000+ but I bought it in May for $110 when the X2 3800+ was available @ $300+. Do yourself a favor and get a X2.
Absolutely, positively you will experience a performance jump. A month ago I saw and purchased a limited time Newegg ad offering Opteron 154's at $260 for the retail package, which includes the three year warranty AND a nifty (6) heat pipe HSF. SOB is not only quiet, but my CPU temps dropped from 112-114F A64 3200+ to 94-96F Opty 154 in the same case (Antec P160 w/two 120mm + 550w PS fan). Moving from 2.0GHz to 2.8GHz definitely shows up
the only reason i was looking at this is the cpu was available on an auction site for a reasonable price ... i know dual is the way to go .. will probably save up for an 3800 X2 . ( going intel is out of the (money!!!) question . gotta make the most of my ageing S939!!!)
Buy 3800 X2 and overclock it to 2.4-2.6 Ghz (5000 x2 level ). Very eazzzy.
So you will be more future proof and it's the cheapest solution available. The optys have bigger cache but it's not worth it considering the price, at best you get 5-10% performance increase at the same clock.
a opteron is real just a cherry AMD64. there a lot like a xf but with locked multiplers. A 148 is a 3700+ that tested very well with heat and power usage. That why there ideal for servers and ocing but if not doing anything like that it's just a cool running 3700. I have a 146 and clocked it to 2.97 on air with temps never going over 44c. Also be sure it's a 939 as they have a 940 that is alwas real cheap on ebay because it needs reg ram and I think is a 1.3nm fab. If you can get a good deal and are up for ocing then go for it.
