I5 2500k or I5 3450

So basically the title says it all. I'm looking to build my first computer in the next couple weeks. Ordered an ssd the graphics card and power supply. Went with a evga 560. Now I'm torn on what to grab for a CPU as well as some suggestions for a motherboard. Originally I was planning on getting the 2500k for 190 after taxes but just found out I can get the 3450 for less than 160 with taxes. Any help is greatly appreciated. Also bare in mind I'm kinda a noob when it comes to pc parts and lingo. Thanks in advance. I should also mention this pc is primarily for gaming like Diablo 3, tribes and any other epic game in the future. Im not sure if I will be doing overclocking so basically im wondering if its worth getting ivy bridge. I already picked out my video card as well as my 700w power supply and ordered them. Graphics card is a evga gtx 560.

i5 2500k will allow for overclocking. If you're not going to overclock, the 3450 will give around the same stock performance.

I'd go for the i5-2500k.
Even if you currently are not planning on Overclocking (which is the biggest advantage. Many start off with NO intentions of doing a OC, but change their Mind, and OPPs (3450)CPU does not support OCing.

The only reall advantage of the IB 3450 is the iGPU - BUT the Vast majority use a dedicadted GPU (dGPU) so for most this is a mute point. The IB series has a 10 -> 15% advantage on a clock-per-clock basis, But again for Only a 10->15 % advantage you need a benchmark to notice it as in Day-to-day performance, not going to notice it.

I was going to ask same question. I know that 2500k is an overclocking monster but what about PCI Express 3.0 ? I have been reading about it and some people say that cards like HD7850 perform better with PCI 3.0 while others say that PCI 2.1 is more than enough.

^ would need to look at some benchies comparing the card in pci-e 3 vs Pci-e 2.1.
Xfire should be higher with 3.0. But also may be highly specific game dependent.

I'd go Z77 board, not much difference pricewise, but allows drop in of ivb later on and access to all of their new features, pci-e 3 etc.

I suspect that the next generation of GPU will saturate PCI-E2x16, there are hints of it now in extreme examples.

Awesome thanks for the tips guys. I think im definitely going to go with the 2500k like many of you said because of the possibility of OCing in the future. And yeah I was also torn on z68 or z77 mobo. Oh and my budget for a mobo is around 130-140 maybe 150 if its worth it.

And yes Im definitely going to microcenter tomorrow to pick up the CPU for that awesome price.

I have an asus Z77 vpro, and that's fine, should be in your price range. But there are plenty of others. There's a recent review of several on toms I think.

I just looked at that z77 vpro and it shows its in the 200 range on newegg. I was looking to spend 150 at the most. Any suggestions are greatly appreciated.

also even though i catch a lot of flack for it:
performance wise there is nothing a z77 motherboard gives over a Z68 Gen3; just a few more bells and whistles that you pay for.
it is anyone's right to dispute this, but i do ask you provide some proof so to better educate me to facts and not opinions :) 
thank you.

if you want your platform to last beyond the next GPU update then get Z77, PCI-E 3.o whilst being necessary now, will become useful with the next gen of cards, i.e. HD8XXX and GTX 7XX.

If you don't mind saving $10-20 now so that you'll have to spend $150-200 a year or two earlier in 2 years time and not 3-4 years time, then go for it.

Can anyone narrow the choices down any further. So we have z77 or z68. If there is a great mobo for the price ill go for it. Im doing pretty good on my budget but if I can save a few bucks on the mobo it would help quite a bit.

I think the only real diff Z68 (w/PCI-e 3.0 support) and the Z77 is:
that it adds native USB3 support vs using a 3rd party USB3 controller, and
additional PCI-e lanes which would only be an issue for a few.

aahhh the old "future proofing" argument to invoke fear. :o 
a Z68 gen3 mobo will also have PCI 3.0 with an IB cpu as with a Z77.

and still even with PCI 3.0 gfx cards the pci 2.0 is barely saturated.

Yes in the US. I mean unless a good price came up for a z77 i dont see a point. I just need a fairly high rated mobo at a budget price to go along with the 2500k.

honestly OP,
it is a buyers market as far as the plethora of choices there are. when it comes down to it; get the motherboard that fits in your budget and your needs; Z77 vs. Z68 be damned!

@OP - if you're going to Microcenter, go with an i5-3570K CPU ($190 - regularly $250) and an ASRock Z77 Extreme4 ($90 - regularly $140) combo.

It's unbeatable unless you can find a 2500K combo with some other mobo for less than $280.

I have that setup and it's rock stable. Plus, you can still overclock in the future and you get a few more fps in (some) games with VirtuMVP due to the better iGPU.

I am in fact going to the store as I am lucky enough to live within 20 miles of one. I was thinking about upgrading to the ivy bridge. Im not sure how that would affect my budget but it is only 20 dollars more. And yeah ive heard good things about asrock, but I also heard good things about asus. If the mobo saves me the money then I should be able to swing it. Also bear in mind I have the evga gtx 560 for a graphics card if that makes a difference

Yeah thats a big factor for me. I may go with an aftermarket heatsink very soon but If there is a very good combo deal then we will see. The 2500k seems ideal but ill find out tomorrow when i visit the store. Hopefully they have some offers with the 2500k

Check my math, but looks like for the exact same amount (and cheapest) you can get a 3570K+ASRock Extreme4 (190+90=280) or a 2500K+ASRock Pro3 or Gigabyte GA-Z77-DS3H (170+110=280). Could save a whopping $5 by getting a microATX Pro3-M.

http://www.microcenter.com/search/search_results.phtml?...

Either way, I wouldn't overclock much on either chip without a $35 aftermarket cooler.

I'd recommend you go with the 3570K. A slight performance bump at any given clock speed and PCI3 (doesn't matter today but might at some point before you replace the system). The 3570K will easily reach 4.4 on an Evo with no voltage change at a very reasonable 60C - that's roughly 4.6 on a sandy (maybe more - depends on what you're doing with it).

Be happy with whatever you end up with :)

alright what about the ASRock Z77 Pro4 LGA 1155 ATX Intel Motherboard. I have just been experimenting adding boards to the cart and then the prices dropped. Also JED they do have the extreme 4 unfortunately its not in stock here in boston. I could get lucky tomorrow but who knows.

yeah I would go with the extreme4 if they had it so Im thinking the pro4 for only 70 is a pretty good deal. Allows me to easily by a 212 cooler

Thanks Mal :)  I pored over reviews, forum comments, and the budget (mine, not the Federal one) to arrive there. Was trying to find the sweet spot between price, noise, performance, power consumption, and possible SLI or CF down the road. Nothing's perfect but think I got close. The whole thing came in just a hair under $1.3K.

hell buy a 2500k HANDS down. there both expensive cpus 200 bucks. and i would never spend 200 bucks on a cpu thats not unlocked i5 all the way and the i5 2500k is faster if you overclock it , u cant overlock the other one

Well the benefit I have is that I can get the 2500k for 180 after taxes or get the 3570k for 200 after taxes. So it boils down to a 20 dollar difference. The other thing to factor in is that with the 3570k I can get a great deal on a motherboard. So unless they have a better deal on the 2500k and a z68 mobo I'll most likely be going with the 3570k and a z77 mobo. Now I just wish they had the extreme4 in stock

So I just found out that sure enough, the extreme4 asrock mobo is in stock today. So im thinking of definitely going that route because it would allow me to get the mobo and I5 3570k for 300 after taxes. Last minute thoughts or input?

Sorry for the constant updates guys but I just found out that I can also pair the 2500k with the asrock extreme4 for only 276 after taxes. So basically it comes down to a 25 dollar difference for the 3570k or the 2500k...

Thanks for all the responses guys, decided to go with the 3570k and the asrock z77 extreme4 board recommended. After looking, overclocking isnt a big deal to me and at most I would be doing very minor overclocking. Rather have new tech to take advantage of and the savings is just fantastic. and malmental i will definitely be getting a hyper 212 as well. any major differences between the 212 plus and the evo?
