So I just got my i5 4690k and am using the stock intel cooler, i want to upgrade it and oc the chip (i do some 3d modeling and want faster renders...) afaik i could spend 60-80$ on a aftermarket air cooler or a corsair hydro (pretty much same temps) and expect to oc to about 4.4 OR i could invest in a 150$ water cooling kit and try and get somewhere close to 5ghz (assuming i can get safe voltages) my question is if its worth the 70$ difference to get an extra 400-600mhz (assuming i dont have a lemon)

side note would it be worth trying to oc on the intel stock cooler first to see if my chip is a lemon or not?

also :p  is it worth overclocking to begin with? Will i see at least a 5 - 10 % performance increase?

thanks

System Specs:
asus z79-a
visiontek r9 280x
intel i5 4690k
corsair cx750m
nzxt h440
adata xpc 1600 2x4gb

Not worth it at all unless you are tring to beat a friend's 3dmark score ;)  lol. At 4.4ghz you wouldn't even bottleneck 2 or 3 video cards.

First things first: DO NOT OC on the stock cooler! They are inadequate for stress testing even at stock clock.

If you spend $60-$80 on a liquid cooler, do not expect the same level of cooling that the same amount of money will get you in an air cooler. In order to get good results with a liquid cooler you're going to have to spend $110-$120 and in order to get good results at high clock speeds, you will have to endure noisy high speed fans.

I am yet to see a 5.0 GHz i5 on air or liquid, so don't expect those results unless you can find someone who has done it.

I can link you to a few people who have stable 5.0 on devils canyon i5's but anyways im jsut wondering if an extra 800mhz or even 400mhz if my chip isnt that good is worth it

you dont need a 70$ cooling for an i5 4690k its not a very hot chip. something like a Scythe Mugen 4 would be enough for allot less money.
overclocking you cpu will boost performance linear so stock frequency is 3.5ghz then a 350mhz increase will boost CPU performance ~9-10%

You can overclock with the stockcooler and boot in to windows to see if you have a good chip. but watch the temps! dont run games or any thing what will load the cpu.

Just because others have done it, doesn't make it a good idea to try.

They likely A) got lucky and got very good chips, B) did extensive tuning in BIOS in order to get to 5GHz, and C) may not be stable enough to do a multi-hour rendering run without creating errors.

My suggestion - get a cheaper air cooler for ~$25 (I'm partial to the coolermaster hyper 212 evo/whatever called this week) and do a little testing of your own. Time how long it takes to have the PC at stock speeds render a specific scene, go to BIOS and bump the frequency up by 400MHz or so, redo the same rendering run and compare the time difference between the two runs.

If you have something that can measure wattage (some UPS's do this) you could even look at the extra power needed to run the OC.

Then decide if the (likely) 10% difference in time is enough of a boost, or if you want to go with a high end air/water setup and push the CPU higher.

I'm personally going to OC my i5-4690K with a Z97-G55 SLI and a CM Seidon 120V. I'll let you know how that turns out once I get the new fans.
