Dang I read each line to make sure to upgrade or not. was a long read but it did worth the time and money that I'm not going to spent on haswell ( at least now ) and to invest money on the 4770k for gaming or to turn of the HT is wast of time and money. If you are going gaming you just need to follow the same path as the IB getting a 3570k and OC DA hell up
a 4 Core CPU 4670K . Aftrer all the hassle to sell old parts and invest on new parts and put more money on top to get this high temp's and very low increase won't worth at all.
just read bellow i was going to quote a lot thing but this last lines can tell you everything.
4Turning off HyperThreading on our i7-4770K helped us out with core temperatures in a big way. This is probably the single biggest thing you can do to cool off your Haswell 4770K. Turning off HyperThreading will knock a quick 5C to 8C off your individual core temperatures in our experience under high overclocks. Doing this hurts the performance of your processor, possibly a lot, possibly a little, depending on your application. To throw some quick numbers at you, when turning off HyperThreadingon our 4770K running at 4.8GHz we saw: Cinebench scores decrease by over 20%, POV-Ray render times increase by 10%, Handbrake encode times increase over 7%, Lost Planet low resolution framerates decrease by 20%, and Metro Last Light low resolutions framerates decrease by 25%. Turning HyperThreading off in our high resolution / graphically intensive game benchmarks, we saw Lost Planet impacted less than 1%,and Metro: Last Light impacted less than 2.5%. So if you are using your 4770K with HyperThreading for workstation applications, a Torrent encode farm, or to play games on a 1024x768 CRT, then you will likely want to leave HyperThreading turned on. If you are using it for "modern" gaming, turning off HyperThreading to give you a better CPU overclock will likely benefit you more than losing CPU cycles with HT turned on.
Lastly, and a bit more on the [H]ard side of things, you can always get the razor blades out and pop the top on the thing. Folks that have successfully de-lidded their Ivy Bridge processors
have seen temp drops across all cores of 5C or better, many times much much better. SonDa5 in our forums documented a 12C decrease, and took awesome pictures to show you the process
. Obviously this comes with the risk of totally fubarring your CPU.
