Which Cpu should I buy?

[crazymonkeyzero]

I'm building a workstation with unbuffered ECC memory within the next few weeks and was debating on whether I should go with the 1155 platform and the new Ivy Bridge Xeons (Intel Xeon E3 1270 V2) or go with the 2011 platform and an Intel Xeon E5 2630. I will be using it primarily for multithreaded applications with support for up to 64gb memory, however, people using the software say that clock speed is somewhat important as well. So my question is essentially whether 16gb of DDR3 1600 memory with the Intel Xeon E3 1270V2(3.5ghz, 4 cores,8mb cache) will be faster ( or rather almost as fast as) the more expensive Intel Xeon E5 2630 (2.3ghz, 6 cores 15mb cache) with 24-32gb of DDR3 1333 memory. The software it will be used for will be Gaussian09 64bit for Linux. Thanks to anyone who can help or give advice on the matter

Have you considered AMD bulldozer cpus? Their 8 core cpus might be cost efficient depending on how well your app is multi-threaded.

On a similar note have you considered a pentium 4 with HT? Slightly faster than BD, but doesnt use as much power. lol, jk........sorta. Id go with the 2011 platform if you plan on doing anything professional.

Come on, even on Cinebench single threaded, the bulldozer is nearly twice as fast as a P4 clock for clock. There's no sorta anywhere in that joke.

Bulldozer does not support ECC memory, plus it's architecture is something left to be desired lol. I guess, I'm going with the 2011 socket Xeon E5.
Thanks for the advice everyone

How could you recommend an 8120 and 8150 to him when he could get an i5-2500k for $20 more? The i5-2500k stomps on any of the FX-cpu's.

8 core CPU isn't needed at all. We're barely getting passed 4-cores. FX-Zambezi is a complete fail.

Lol wow... so desperate as to compare it with a P4? Hahahahaha... thread ends here folks.

Read the OP before threadshitting. This was for multithreaded performance, and the OP elected to go for a 6core xeon so more cores obviously benefits him. Doesn't change that bulldozer don't have ECC support or would perform worse than the xeon, but still this is getting tiresome.

Two/Three 1155 clustered boxes might be a better option. For the same price
