Core i5, Core i7 or Xeon E3 ? ....my old CPU Q 9550

Hallo, for my new Audio PC Win7 64bit what CPU are the best for my money, i will not overclock the CPU ?

Intel Core i5-3570 Boxed 4x 3.40GHz for 177€
or
Intel Xeon E3-1230 v2 Boxed 4x 3.3GHz for 200€
or
Intel Core i7-3770 Boxed 4x 3.40 GHz for 250€ ?

Did i need a new CPU, i have Intel Q 9550 @ 4x 3.20 GHz(overclock).

im certainly going to say the 3770 ,as it is proven to be a very good processor for DAW but know doubt someone will suggest going for something newer . The 3770 does not over clock anyway and to be quite honest unless your going to be using 800 tracks of vsti’s ( bit over exaggerated ) you will not be anywhere near the limit on this baby , there are very good for the buck

Pointless getting an i5 3570 unless you are willing to overclock, they are designed for overclocking, saying that, if overclocked correctly with a good motherboard they can outperform i7 easily.

I’d recommend Xeon.
Have a look at the specifications of the HP series Steinberg suggests as ideal hardware for Cubase and make your decisions based on that as a model.

Finest software requires finest hardware. That’s why our best software specialists rely on the world’s leading PC hardware manufacturer. Cubase 7 is quality-tested with HP’s professional Z series workstation computers, ensuring highest performance and maximum reliability packed in a rock-solid chassis. Carefully selected components optimized for recording, editing and mixing allow for efficient audio data transfer rates throughout the whole system. Be it the industry-proven Intel XEON processors or the ultra-fast SSD drives, HP Z machines squeeze the best out of Cubase, speeding up your entire studio software environment.

Steinberg moderators DID also recommend the z77 chipset for running your DAW as that was what they were using for test benching last year as well IIRC

With the E5-2687W Xeon being the top dog! But look at the price (double that for two), though if you NEED the capacity, it becomes a matter of scheduling the outlay.

I am doing the same thing right now. I purchased a 4770k and a ASUS z87-pro http://www.newegg.com/Product/Product.aspx?Item=N82E16813131992 so I could use thunderbolt in future. Powercore 7850 2gb radeon card http://www.newegg.com/Product/Product.aspx?Item=N82E16814131472. Also if you need firewire this is a great TI chipset PCI-E card recommended by Universal Audio http://www.sonnettech.com/product/allegrofirewire800pcie.html or this one http://www.siig.com/it-products/firewire/firewire-800/pcie/dp-firewire-800-pcie.html

Here are good benchmarks http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E3-1230+%40+3.20GHz
comparing all but newest cpu
Good luck and let us know what you do, remember that the technology changes rapidly and also Intel just came out with a new 6 core processor, I am sure the 4770K will be more than enough though.
