4670K versus 4770K

So having recently rebuilt my rig/ watercooling loop to include a 2nd 7970 I kinda got the itch and decided to move from i7 920 to Haswell. Have already got the Maximus VI Hero and had planned on pairing it with a 4770K and a 16GB kitof Corsair Vengeance Pro (red kit). Altho can't find anywhere to have any of the 16gb kits at the higher frequencies (2133Mhz+) so decided to look at 8gb (2x4gb red kits) as can always add another 8gb down the line if required. That got me thinking about the 4670K as well and I have discovered I can get the 4670K and 8GB 2133Mhz Ram for about the same price as I would pay for the 4770K.

So, I obviously know the differences ie. no hyperthreading and less L3 cache per core, but speaking from a strictly gaming perspective - the pc is used for little else than gaming and browsing - is the 4770k nearly £100 better than the 4670K? Add in the fact I have 2x7970's, does that affect my decision - will the 2 threads per core better make use of the gpu horsepower significantly?

Also, is 8GB quite sufficient these days? I'm coming from a nearly 4 year old EX58 with 6gb.

Cheers.
 
It is worth the extra for the 4770K imho, phenomenal performance for the money. The extra grunt may be handy for dual GPU's. 4770K really is performing around 3960X levels, while using much less power. It's def worth circa £250.

dont go from a 920 to an i5.

i went from a 920 to a 4770k and like boom said, its good.

Agreed, went from a good 920 to a 3570k, bad move with sli. Went to a 3770k but building a 4770k rig next week. Got a good price on the cpu so couldnt resist.:D
 
I went from a stock i7 920 to a i5 4670 (non k) as I don't encode much or overclock. Playing games such as battlefield 3 and Tomb Raider. I did notice a difference and I'm running them with 6970's in xfire.
 
I've got an i7 920 @4.2 and I'm hoping to make the move to a 4770K at the end of the month. The lack of Sata III and USB 3 is starting to annoy me. Plus, I want toys to play with. I reckon if I can get the 4770K to at least 4.4GHz I'll be happy.

Thats a other reason why I upgraded. I having a Samsung 840 500gb SSD would be a waste on SATA 2 and some of my external HDD's are USB 3.

Same reasons as me really. Plus I have a feeling I am bottlenecked a bit with my 2x7970's (hard to tell as not used it much since rebuild)

Just ordered a 4770K. :D

Now to decide whether to de-lid and possibly mount naked? Will see how temps are under my Raystorm block but have read bad things about the heat getting trapped between the core and the heat spreader.
 
Went frpm a i7 930 at 4ghz to a 4670k - 3dmark phys score only marginally better but gfx score improvement is massive and all games play at a solid 60fps on 3150x1680 - most even at my full res 3600x1920 on my surround 3x680 setup. Video memory is the limiter there, not cpu or gpu capability. If youre mainly gaming a 4670k is an easy choice that saves a few quid as well. For encoding the 4770k is obviously better.
 
I upgraded from an i7 860 (2.8Ghz) to the i7 4770k and it's a fair bit faster

I am using the same GPU, so at the moment most games are still GPU bound but a few titles have clearly had a boost (Battlefield 3, GTA IV) plus you also get the benefits of SATA III, PCI Express 3.0, USB 3.0 etc etc.

I'm more than likely going to get the AMD 9000 series cards next so that'll provide the greatest boost to framerate.

Good choice, awesome CPU. Really wouldn't bother with delidding, you will probably reach 4.6Ghz under water without delidding, which tbh is more than enough, the CPU is very fast. Why take the risk of breaking it? You're braver than me, and I ghetto modded my 780 :p. Wouldn't wanna touch that CPU lid lol.
 
Delidding is risky but easy - delidding doesn't improve overclocking ability of the chip but could allow you to reach the top oc more comfortably if temps are the issue. In general, setup the system, oc it and see how far you go and what temps are. Then decide if a delid is worth the risk.
