LGA 1155 I5 vs I7

post #1 of 31
Thread Starter 
I had set my eyes on the i7 2600 K but after reading some of the other threads in here it seems that this wouldn't be the best choice for a gaming rig.

As far as i understand the 2600 K has in general 4 cores (8 when Hyper threading is enabled) the more cores you have the better it is at multitasking. But this is not crucial for gaming as far as i understand.

The bit where i get confused is the 2600 K has 2 mb cache dosen't that amp the performance abit? and is it the 90 Euro's worth gaining another 2 mb cache and 100 MHz more?

Hope you guys can help me out here and thx in advance for the answers.

2500k for epic gaming and someencoding/rendering etc on the side, 2600k for epic rendering/encoding and epic gaming

If you aren't going to heavily use the cpu in encoding tasks etc, 2500k is top notch mate

Disregard the clock speed, you will be looking at getting more than 4.5Ghz on air anyway once overclocked

Edit: If you are primarily gaming, the 2500k is the best choice, end of, unless you want more power for heavy tasks. Don't let that sentence put a down on the 2500k though, it will eat, spit, and re-eat any game you throw at it, with a good gpu of course

Unless you know you can take advantage of Hyper Threading, don't waste your money. You might get an extra 2 or so FPS in games.

I'd get the 5 (and i did), and pocket the difference in price. It's excellent value for money at the moment.

The 2600k is alot more cpu , for a $100 or so more! ( imo)
Really depends on what you need ?
I personally would get the 2600k ( if your worried about money then get the 2500k?)
are you going to overclock? if not maybe the k series isnt for you?
Here is a nice review and comparision to help your choice!

Now I admit it, I was rendered speechless by the performance of what initially was expected to be a mid-range series processors. Now the Core i7 2600K at just over 300 USD is not exactly a mid-range price, it however is and will remain the fastest quad-core processor currently available on the market. I can recommend this processor very very much. When you opt to step down to the Core i5 2500 then you'll forfeit on hyper-threading, get 2MB less L3 cache and the core clock goes down 100 MHz. It will save you some money alright, but the performance decrease is very much noticeable and measurable. It's still a very fast quad-core processor for the money. But yeah, we can't help it, we've fallen in love with the Core i7 2600K very much. That processor seems to have all the variables right.

the fps performance in game is very much up to your gpu!!

That's why I said the gains are negligible.

He wasn't doubting it is a more powerful faster CPU, he was saying, quite rightly, that gaming wise it isn't worlds different from the 2500k. Guru3d are more than likely taking into account the performance over HT applications and rendering tasks, encoding tasks etc

Gaming only, 2500k is going to be a better buy unless you really don't mind spending the extra money

Thread Starter 
Thx guys that made up my mind i'll be going with the 2600 K that review was what i needed to make my choice REP + for all of you

Now all i need to do is make my choice on a case allready made a thread but apparently no one dares to give me advice on it must be some predicament iv'e put myself in with those 3 cases to choose from.

Regarding overclocking i'm definitely a noob on that area but watched the video commercial for the 1155 CPU's "so easy even your grandma can do it :-P" so i'll probably google it or make a thread in here and ask for some pointers on oc'ing the CPU.

Here is the specs for the build im making

Core i7 2600k

Asus P8P67 PRO B3

8 GB corsair 1600 MHz Vengeance CL8 (2x4 GB Dual kit)

Corsair Hydro H70

XFX 6950 2 GB version

WD 1TB caviar black 7200 RPM 64MB cache

XFX 850 watt black edition

OCing a SB processor couldn't be easier.

1) Raise the multi until it's no-longer stable
2) Raise the vcore and repeat steps 1 and 2.
