Core i5 4570 vs core i5 4670

Hi,
I am debating which cpu I should get for my first build. The i5 4570 is 3.2-3.6 and the i5 4670 is 3.4-3.8, so they are quite different in terms of performance. My question is would I be able to play high demanding graphic games such as crysis, bf4, etc with the 4570 or I would be better off with 4670? I have an all in one lenovo B320 core i3 and I cant play any of these games due to the cpu speed and not efficient graphic card, so I am deciding to build my own pc from scratch even though it would be more expensive.
Any comments appreciated.
Cheers

If you're getting a Haswell you might as well get the 4670k. Why? Because Intel removed the +4-bins OC feature from non K chips on Haswells vs Ivy's so all the non-K Haswells are actually slower than the Ivy chips they're supposed to replace (with a Z77 motherboard). Eg:-

3470 = 3.2GHz Base but can be OC'd to 3.8-4.0GHz (3.4-3.6GHz Turbo + 400MHz)
4570 = 3.2GHz Base but can be OC'd to 3.4-3.6GHz (3.4-3.6GHz Turbo - NO extra +400Mhz "limited OC")

3570 = 3.4GHz Base but can be OC'd to 4.0-4.2GHz (3.6-3.8GHz Turbo + 400MHz)
4670 = 3.4GHz Base but can be OC'd to 3.6-3.8GHz (3.6-3.8GHz Turbo - NO extra +400Mhz "limited OC")

Overall, Haswell's are 1-10% faster (more efficient) than Ivy's (depending on game), but Ivy non-K's are a constant 10% faster vs Haswell non-K's (due to +4 extra multipliers) under all games.

So believe it or not, an i5-3570 (non-K) is faster at max Turbo than an i5-4670 (non-K). My advice is to either get a 4670K (performance) or a 3470/3570 (budget). The non-K Haswell's are actually a step backwards as they run roughly 400MHz slower than their non-K Ivy Bridge predecessors on a good motherboard.

get the best you can afford. but with either, the GPU will play a more significant part in performance compared to the cpu. Building a pc from scratch shouldnt be more expensive. all in ones are more expensive (for the specs you get) all in ones often house laptop components, which are slow.

I do not plan on overclocking and the GPU I will be getting is MSI Gtx 760.
The i5 3570 uses Intel® HD Graphics 2500 and the fourth generation uses Intel® HD Graphics 4600. My question is does the cpu graphic also plays a crucial role when it comes to playing games and is the HD 4600 better?
If the fourth generation performs worse than the third then what advantages are there in the haswell cpus compared to the ivy? Lets say I bought the i5 4570 with the gtx 760, would I be able to play games that I previously mentioned?

If you're using a GTX 760, then whichever CPU you use, the iGPU will be disabled anyway, so no it doesn't play a part. If you don't intend to overclock at all (inc using Turbo Boost), then Haswell's will be slightly better. A mild 10-20% OC gives a certain amount of "future proofing headroom" for heavy games in years to come. There is no actual advantage in locked Haswell's vs locked Ivy Bridge other than the iGPU (which is irrelevant if you use a GFX card) - one reason why many with hardware 1-2 generations back are simply not upgrading. And yes, you will be able to play all games previously mentioned even at stock.

If the IGPU will be disabled then what is the purpose of having the graphic chip on the motherboard? Sorry I am a noob. I thought that the turbo boost is activated automatically and does not have to be overclocked once the system needs to run faster to cope with higher demand. What are some of the advantages and disadvantages on the third and fourth generation cpu? Do you have any recommendations for the third generation cpu that runs from 3.4-3.8 without overclocking?

The GFX chip is actually on the CPU rather than the motherboard, and the main purpose is for non-gamers to not need to buy a discrete GFX card. Turbo Boost often is activated automatically, my post was just to show that the newer Haswell's won't Turbo up as high as the older Ivy Bridge chips, and the "gap" between new Haswell's and older Ivy Bridge's is non-existent for non-K chips.

Fourth gen i5's are 5-10% more efficient overall but can be OC'd 10% less. 3rd gen i5's are the reverse (5-10% less efficient but can be OC'd 10% higher). If you don't intend to OC at all, and want the fastest "out of the box" CPU, then just buy a Haswell i5-4570/4670.

I bleive that hasswell 4670k beats ivy bridge 3570k by 10 to 12%
forgot to say: hasswell has only one advantage that it is more powerful than ivy core for core

yes both those cpu can play that game it will depend more on your graphic card.
