- runs cooler w/o l2 cache
- about $30-40 cheaper
- new E4 060x chips OC avg 2.6-3.0
- 10x multi
- less likely to have cold bug(?)
- L2 cache gives a few(?) % points adv
- better binned, less likely to overvolt and die(?)
- famous OCer should pull at least 2.6 stable(?)
-runs cooler w/o L2 cache...Sorry, it has a 2x512 l2 cache. It's just smaller...
-the new ones are E6, the old ones are E4; regular oc's are more likely between 2.4 - 2.6 1:1 and 2.5 - 2.8 using dividers, unless you really want to push them (with special cooling).
-cold bug is a myth...cold bug came about when people were trying to run too much voltage while at extreme temps...too much voltage being the key term there
-L2 2x1mb cache will give a 1-3% improvement in intensive tasks (over 2x512k cache)
-definately better binned, and typically can overclock to higher fsb on lower voltage then the equivilant x2 series (which doesn't exsist in this series since there isn't a 1.8ghz x2)
-Can overclock to 2.6, but not necessarily will.
-1.8ghz processor vs 2.0ghz X2 you're comparing (@ stock)
Motherboard, ram, psu and hsf are all issues that need to be addressed as well in an oc'd system.
Edit: Oops didn't answer your question...I'd pick the opti personally...but that's mostly because i've already oc'd a 3800 x2. It's pretty much a toss-up. Go opti for the prestige...heh. 3800 for the higher base clock...
