i've been offered an i7 4770 Haswell for £190, but i've read just now that it's not as good for O/C and gaming as mine (gets too hot) and struggles to reach 4.6.....is this correct

if so which is the best for me......or the best of the Sandybridge/ anything else

thanks
 
You need HT in BF4/Crysis 3 and perhaps a couple of other games to get the most out of them. Otherwise a 4.5+ 2500K is still fine for 1080p, unless you intend to use 3+ graphics cards.

What I did was traded up to a 2600K to get HT.

If you think you won't be happy with 4770K, wouldn't even bother with it tbh. Either grab a 4790K + Z97 or wait until X99.

4790K's are great lil chips, and X99 CPU's even better when they arrive.

I read somewhere that Intel has been taking all the best 4770 chips to make 4790 chips since last year.

Yeah people have been posting their manufacture dates, saw one earlier July 2013! 4790K is a nice cool-running Haswell with a very nice 4.4 turbo.
 
And the 4790k's are still as hot as the 4770k's. The new improved TIM is a myth. Of course the high temps are only reached under certain synthetic stress programs.
 
You will see no performance increase over your 2500K really. It is essentially the same chip.

3770k would be the most cost effective upgrade IMO.

yes this one is the best, but costs more than the Haswell offered to me at only 190 quid

but:- the i5 will o/c higher than the Haswell, but then again a lower overclock on the Haswell of 4.4 will probably be more powerful than a 4.7 on the i5

i'm now a bit confused, i dont know what to do..........will the i5 be able to handle this next AMD R390X at 1080p

these guys delid the cpu to reduce its temps .......... but i lap it instead, the best is to do both, there's quite a few videos there

Delidding can see drops of 20c Ono. Unsure about lapping on theese, last cpu I done that on was a q6600. The problem with hw chips is the heat transfer. Intel use rubbish paste then use way too much black glue to hold the ihs in place therefore its not close enough to the cpu die.

It wasn't 20 degrees m8, it's 30 degrees:eek::eek::eek::eek:...now you lap the tower and the cpu lid as well ( when the lid is removed) and this'll drop it another 10 degrees.....he retested his at 60 degrees on 4.6 ...without lapping, so that's brilliant

mine is lapped and here's what you get on full Prime.

THERE'S NOTHING WRONG WITH THIS PROCESSOR THAT CANT BE FIXED

yes too much cheap paste...badly applied...too much glue, our GPU heatsinks will be the same too

Yet to see anyone on here lap a haswell yet. Could be worth trying along with delidding, warranty is gone either way. This is my third haswell chip, 1 4770k and 2 4790k's. The former reached 94c at 4.5ghz, the latter two get to the mid 90's at stock under p95. Its only on AVX2 instruction set programs such as p95 28.5, certain versions of ibt that gets them thus hot.

yup and that's why it wont go over 4.5, but this should reach 5, because his was only 60 degrees at 4.6 :eek:

i've done it loads of times to my i5/AMD and this one is even easier because it has no pins on the other side ;), a cpu is pretty strong, but you still have to be careful.....but the The tower is easy to lap..

this Haswell is now worth buying, but before seeing this on Youtube it was a waste of time

warranty? well yea it's a risk you take, but the cpu is pretty strong, the only thing you deffo have to watch out for is STATIC from your clothing !!!!

Iirc with the q6600 I dropped temps from 82c max down to 68c max by lapping it and the TRUE cooler I was using. Chip was running at 3.8ghz.

good one m8 ;)

Maybe lapping might be enough, but the i5 still overclocks ok without lapping, so this points to the Haswell being far worst and so bad that lapping isn't enough

i'll use normal high quality thermal paste
