I have a new build in design and realize that if I go with a 2500k and overclock it, id need a Noctua D14, Higher end Mobo, a case geared around cooling (Cooler Master) and some extra fans no doubt.

However if I just decide to go with a i7 2600k, if I dont overclock it I believe performance would be similar and instead of spending about an extra £150 but if I just go with i7 2600k instead of i5 2500k, its only a £95 difference....

Is the extra £60 justified considering the tweaking needed as well to get the CPU overclocked

Am i missing something or looking at this wrong?

sure if you support that price then you should take the i7 it will worth

get the 2500k no huge difference between them 2600k is only 100mhz better but doesn't matter they both have a similar performance 2500k is much better with lower price and overclock heavily to 4.8ghz or 5ghz with a decent cooler they both are quad cores

dude... you dont need a excellent motherboard to overclock....
there are people that oc with the cheapest motherboard on the market... , as long as its a z68 of course... and its about 110$ us
oc'ed.. it will burn the 2600
fan? why noctua? its freaking expansive... a Xigmatek will do just fine
the rest of your casing doesnt matter much... you wont need that many fans... unless your room is most of the time above 30 celcius

you could also get a 2600 (NO k SERIES) with a 60$ mobo... and be less powerfull, threading isn't that usefull since not much application use it...

Ah thanks

A lot of people were telling me (or at least I was reading their words) that not just any Z68 would do... thats good as I can get an MSI Z68 for a good price... has the ports etc I need.

I suppose going noctua is a little heavy duty, I can get the Xigmatek for about £15 so that saves me some coin.

I live in the UK, even in summer we are lucky to get indoor temps of above 26, mostly it will be around 15-17 degrees indoors.

So to summary, I can save about £30-40 on my mobo, £30-40 on my heatsink and perhaps another £10-20 on casing... that could help

get a p67 or z68(to oc gpu) and a cm 212+ hyper or a better cooler and oc i5-2500k and it would be close to similar oc in i7 (over 95% performance of the i7)
investing in i7-2600k when u can oc i5-2500k is no brain

Up to now, just some applications use up to 8 threads, so 2500k is very nearly the 2600k. So you can OC it or not, up to you. Depends on what app. you do everyday. If you do image editing or video, should get the i7.

if u see a i7 , there is no question
but when u can get quite same thing at 2/3 price , then whats the debate ?
yeah it still depends on your use.
if u still not get a comp then get i7-3820
it is $285 i7-extreme , it aint fully unlocked , but u still get upto 4.5ghz

The gentleman is right and wrong, not all motherboards are equal however he is right in that you do not need a $300 MB to overclock well, MSI makes a good overclocking board on the z68 platform if you are planning on running 3-way sli or something super high end. Toms has many MB reviews about features and even overclocking performance I would look them over and READ them dont just look at the performace numbers sometimes the fastest board is not the best for your application. The stability, layout, ease of overclocking may matter more, and usually do as the speeds usually vary by less than 2% borad to board(there are some exceptions). But I agree in some ways, You do not need the BEST MB but I would not buy a cheap MB , Some boards have slow transfer rates on HD controllers this is something to avoid . My suggestion is usually ASUS 1st, Then either Gigabyte, MSI, or ASRock but there is some differace model to model and platform to platform. If you go cheap ECS is a ok Cheap brand I am not a fan of Biostar or FOXConn for a high performance system you plan on upgrading, ok for your mom but not for an enthusiast pc. EVGA has some good products with lots of features but they are not a MB specialist I would stick with the first 4 brands I mentioned.
If money is an issue spend a little less on a processor and more on Graphics, faster HD(possible SSD) , and a Mid range MB you will get a better result. What good is a high end CPU if you cannot utilize it.

see the use of cpu depends on the app , if u run something like designing or other heavily threaded app , then go with i7 otherwise i5 will get you pretty much the same thing.
if we talk about the motherboard , when taking a unlocked cpu , take the p67 or z68 ( currently) , both oc well , z68 has some extra features. in terms of overclocking , z68 provides ocing gpu through bios.
in case of fan the Xigmatek Gaia SD1283 has these results
it means means that oced cpu has 3 celsius and you cant see temp in idle
the case was Rosewill Challenger-U3.The low $50 purchase price includes two 120 mm fans, plus a single 140 mm blower.

so thats the conclusion
