Well, while asking for advice on what to build for my friend from UK, i suddenly got that upgrade fever as well. Sad

Now, can anyone tell me if it's really worth upgrading from a i5-2400 (stock speeds mind you, my mobo won't allow OC), to a 4670k with whatever OC i'll be able to get on air?
Will the difference be noticeable in minimum frames ?

I'm doing lots of things with this PC which range from work - photoshop / vegas / illustrator
-to-
gaming - Blizzard games (WoW/D3) + some of the most demanding games that will come out (then again those are mostly gpu intensive).

Any point picking the 4770k over the 4670k? I keep hearing conflicting information about the subject, as long as it's gaming related only .. not worth it? But will those "extra" (HT) cores .. come in handy ever? (gaming).
Also, bad time to upgrade CPU? Should i wait for the next batch? Will there be some major advancements?

I really don't want to repeat the error i've made when i bought my i5 2400 instead of getting a i5 2500k since i was like "meh won't ever OC, who cares".

Hope you can help me out with some opinions until i decide what to do. Cheers.

prolly it is.... but maybe You should wait.

It seems like real 8 cores cpu's will be needed this gen so not even i7 is enough yet as HT don't really count.
If You really want to get something then it MUST be i7 because of HT but i would wait.

I was going to ask the same, though i use an i5 2500K @3,3Ghz without OC.

But that'd mean you'd have to change motherboard too, since 2500k is LGA1155 and the newest stuff is actually LGA1150..Same thing would happen to the CPU Cooler's Socket, as it might not be compatible (Mine's a Thermaltake Frio OCK though it's said it's compatible)..

I might be wrong,i'm not a pro at this..Just posted my opinion

I've heard that actual motherboards/CPUs like ASUS's P8Z97 boards and Intel's 4th Gen (Haswell) gives only a 10-15% performance improvement over Sandybridge...Don't know how Skylake will perform..

Like Farne said, wait for it or we all might regret it whenever we upgrade the Mobos and CPUs

I prefer a big jump over a tiny one...as long as processes and renderings and stuff goes more faster than ever...

Thing with skylake is, 2015...

Now It's may in 2014. Not a very patient person Razz

And wondering again, anything special about this skylake that will make it so much more of an upgrade compared to say a jump from 2xxx to 3xxx or 3xxx to 4xxx ?

Also considering the die shrink or whatever you call it, apparently it will run even hotter making it even harder to OC. Wrong/right?

haswell refresh K series are picked for the better silicon from the wafer and the good old solder TIM we knew from sandy bridge , i would wait for reviews how high they clock and then you can decide if its worth the upgrade.

With a 2500K/2600K/2700K there's little to no point, at least not until we've seen these "fixed" Haswell K's.

I'm on a i5 2400 at stock with no possibility of overclocking whatsoever so... unless your comment was more like a general one and not directed at me.

They're coming out early next month right?

I meant K-series CPU's. Your CPU is as you said insipidly difficult to overclock beyond the turbo speeds depending on how far you can take the baseclock (I doubt you'll get 105MHz stable, that's the limit for most Intel 6, 7, 8 and probably the 9-series based boards).

Can't take it anywhere due to the mobo being a h87 (iirc). So no options to OC it at all Razz

It's kind of annoying though, can't really find any proper answers whether to go i7 or i5. Been reading forums on the subject for a few hours now. So much going back and forth yet (for obvious reasons, unless someone has a magic crystal ball) no one knows if HT will be useful in the future for games. I7 is better for apps at least, but also harder to OC compared to a i5?

Apparently according to gpgpu or something (russian site), you can see quite a difference in BF4 MP on a 4770k vs a 4670k (around 15-20% more frames) both on stock.

Definitively a quad core, overclocking is useful but you should have no problems reaching 4 Ghz, possibly over 4.6 or so with voltage tweaks depending on CPU and motherboard.

Upgrading now and then say getting a new GPU in 2015 and you're going to be pretty much set, Skylake is also coming out so you could save up to that and wait but you could upgrade now as well without having to swap to DDR4 which will save on costs a bit.

z87 or z97 motherboard should be good, k or non k CPU mostly means the multiplier is unlocked though you do have to pay extra for those k series Intel CPU's though I am not that up to date on what their multiplier is locked at.

If the 4670 is just a lowered clock version (And perhaps lowered cache memory.) of the 4770 then there's no real harm in picking that since it's likely going to cost less and the small difference can be made up for by overclocking it slightly.
(Games like Battlefield 4 with good CPU utilization will show a nice increase even with a small bump in speed though that game can also use more cores if available, Frostbite engine is quite scalable.)

If it hyperthreading then that's good to have but not essential, especially for gaming results can be a bit hit and miss though I keep it enabled anyway.
(As I see it four physical cores is still going to be able to handle things fine.)

Not much else for me to say, something to think about but it's up to you what you decide to do. Smile

For gaming I believe your current CPU is still doing a adequate job since we're still primarily GPU limited although CPU usage has increased (Improved?) these last couple of years which is why I'm definitively recommending a quad core as minimum, will also help with media and other PC tasks.
