This ill be very general, but I am still confused...

IDK whats the best i5 or the worse i7. But should I spend the little extra money to get the i7.

My brother has a i5 3.4 ghz(haswell) and when he plays bf4 beta, his core is working up in the 90% and it got to 100% in some peaks. So yea? does this even mater?

More about : worse

BF is CPU intensive, so those numbers make sense. You can still run BF4 just fine on an i5, but if that's your focus and you want it sucking all your CPU to run, go for an i7. It will definitely make a difference.

IB i7-3770 would be a good choice, at under $300 and excellent speeds: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My i7 at stock only gets up to 50% usage. I'm telling you now, hyperthreading makes a massive difference! It was just never used in the i7's before, but in about two years i7's will be at least 2-3 tiers above the i5's!

Just pony up and get an i7-4770K. Or if you want to save money, get an FX-8320 for $160 and it will be in between an i5 and i7 for WAY less money!

really? I thought that for games, the virtual cores are pretty useless. so a i5 3.4 should perform about the same as an i7 3.4

and will the integrated fan work well with it. Or do you recommend to buy an external one. I remember that the i7 used to get very hot. IDK about now.

You definitely want an after market cooler on an i7, even if it's just a Cooler Master Hyper 212 model.

If hyperthreading didn't help than i3's wouldn't be destroying pentiums in the benchamrks of crysis 3 and BF4.

Overall I would say hyperthreading gives a 50% boost in performance when properly utilized. It is indeed worth the extra money if you use high end GPU's...

They're virtual cores, that can be used by OS/programs as though they're actual, physical cores:

"For each processor core that is physically present, the operating system addresses two virtual or logical cores, and shares the workload between them when possible. The main function of hyper-threading is to decrease the number of dependent instructions on the pipeline. It takes advantage of superscalar architecture (multiple instructions operating on separate data in parallel). They appear to the OS as two processors, thus the OS can schedule two processes at once. In addition two or more processes can use the same resources. If one process fails then the resources can be readily re-allocated." - Wikipedia

In certain applications, hyper-threading effectively doubles the CPU core count.

It was a beast among Dual Cores :D

Two lines of code can run on each core at a time. It's like if you gave me two things to cook at once instead of just one at a time. I would get them done faster than if you made me cook each part of the meal separately, but I would not ever be able to cook two things quite as fast as two people doing it!

However if I was really good I could come close, and that is ideally what hyper-threading does when utilized correctly. And it is utilized A TON by the i3's and soon i7's.

i7's run fine on the stock cooler unless one of the following conditions fits you:

* you are planning to overclock more than a little bit
* the stock cooler is too loud for your tastes

otherwise, it will work fine. In fact, I use one on my non-overclocked i7-4770k in a mini-itx case and it's fine. not even too loud for me.

hyperthreading shows a second core for every physical core to the OS. it's opportunistic though- though there are 2 pipelines, 2 instructions don't always get run. some mechanism in the CPU determines if an instruction in the first pipeline is currently using the physical core or if it's relatively idle. If it's relatively idle, it feeds the instruction from the 2nd pipeline.

On well threaded applications, this can improve performance over non-hyperthreaded CPU's of the same architecture and clock speed by about 40%.

I could easily be wrong on whether hyperthreading has a big effect with gaming but my understanding is going from a pentium to a i3 is going from 2 to 4 cores seen by the OS, but going i5 to i7 is 4 to 8. A lot of games can take advantage of a 3rd or 4th core, but not that many can take advantage of a 5th or 6th, let alone a 7th or 8th.

Did you mean to reply to my post? haha not sure if i was supposed to respond to this...

Wait, im not planning to overclock my i7. Not even a bit, too lazy...(lol). So the stock fan should work in this case. I will only overclock my GPU,(Gigabyte 770 windforce).

Obviously your decision, but I don't overclock my CPU and I still wouldn't run the stock cooler, they're crap.

If you are not gonna overclock, get this:

It is basically an i7 for the price of an i5!

I am obviously a begginer in this. But i saw them, and I see no difference. Just that one doesn't have integrated graphics and the other does. How do the benchmarks compare?

I'll stick with the i7, thx for the feedback anyways.
