i'm going for a dual socket + quad core CPUs build dedicated entirely to SINGLE-THREADED game server software
everyone keeps recommending Nehalem over Harpertown so i guess i should just take the advice and do away with Harpertown already
So im lost why do you want more cores then?
Are you gonna virtualize and run a series of servers on 1 machine?
Whats your main objective?
No. Opterons are a touch slower than harpertown per clock. Considerably slower than Gainestown per clock. You will need a 2.5 GHz Opteron to approximate a 2.33 GHz Harpertown.
The Opteron 2380 is a 2.5 GHz 45nm quad-core that goes for about $325 at provantage, about $65 more than a 2.33 GHz Harpertown. Therefore you are better off getting a dual socket 771 system unless expandability to a 12-core server is important.
No right now the quad socket optys + cpu's are VERY VERY cheap.
Even almost at a steal if you look though ebay.
Which is why i was pushing him on a 16c opty system.
However im completely lost in the OP's objective now..
I was thinking he would run a bunch of servers off 1 machine.
16C ~ 14 instances of virtualization where each is a dedicated server, and leave 2 cores for the OS and maping.
If all you need is 1 server.. or even 2-3 why are u even going on server?
Grab an i7 set HT ON, and let it fly.
Dont bother with enterprise... you can get a workstation i7 which has near reliability, and be faster then the harper.
Give the i7 a slight qpi bump, since were not talking mission critcal DB's, and you can even give a 2 socket harper a good run for its money on a single socket i7.
If you even have the budget to invest, grab a single gulftown then.
6c/12t is an absolute monster.
I would know because im on both a full blown gainestown server... which is a dual i7, and a single gulftown.
