I'm finally around to building my desktop but I'm stuck at which cpu to go with. Originally I was going to get the i7-960 and I can get it at microcenter for 200. But lately after reading a lot it seems everyone is pushing for the sandy bridge processors. I really would like the 2600k but its 100 more than the 960 so the 2500k is more in my budget at 180. What disadvantages would there be in going with the 2500k vs the i7-960?

I will be doing quite a bit of gaming but also a lot of engineering modeling (solid works, inventor, etc) and not sure if those programs would take advantage of hyperthreading or not.

The rest of my system

Cooler Masters Storm Scout Mid Tower
Corsair 750W TX750 V2
1TB WD Black Caviar
16GB Corsair Vengance
150GB WD Velociraptor
ASUS Radeon HD 6850
2 23" ASUS LCD Monitors

Nothing really apart from SLI/CF.
The bloomfield series have pure 16x/16x cf/sli speeds that is what the 1155 sockets lack currently.Here is a review of the speeds.

On the other hand when you pair a i5 2500k with a good p67 mobo you have great overclocking finesse.

The price of the mobos really are still over the top for bloomfield that is i7 900 series.

Here is a look at the p67 mobo for the i5 2500k and the x58 mobo for the i7 900 series:

Yeah I doubt I will be CF my gpu and I have noticed the prices for x58 mobo tend to be a lil higher than the p67's i was looking at. I think the 1155 will have more upgradability if I decide to upgrade in the future over 1366. I guess my main concern is will I see any noticeable difference not having hyperthreading in the i5...I'm pretty sure that the modeling software takes advantage of that

In the battle of performance between the 1st generation Intel® Core™ i7-960 vs. the 2nd generation Intel Core i5-2500K comes down to if the software that you are running is multi-threaded and if so how many threads can it support. In applications like video/audio and heavily multi-threaded applications then the Intel Core i7-960 might have an advantage. In everything (gaming) else the Intel Core i5-2500K is the clear winner in the performance and value vs. performance as a matter of fact it is almost impossible to get better performance right now then what you are going to get from the Intel Core i5-2500K in gaming and standard applications.

Thanks Christian...you pretty much made up my mind. 2500k it is

If you have not ordered any parts yet then drop down the velociraptor and use that money to get yourself the i7 2600k. The availability of HT on it will give benefit to whichever program that can use it and peace of mind to you. Autocad won't show much benefit with HT but solidworks will.
