Hey All,
Im new here and im gonna build a rig for the first time, which cpu should i get?

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K
Or
Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I72600K

Which 1 is better for gaming and easy browsing
Thanks in advance :)

Get the i5. You don't need an i7 for gaming and browsing.

I'd go with the Core i5 3570K since it's cheaper and HT isn't an important factor for most games.

Performance overall is similar between the two.

The i5-3570K or the i5-2500K are he cpus that wrk best for gaming , an i7-2600K or i7-3770K will have hyperthreading and be great for photo editing or video encoding ad applications like that. Games can not take advantage of the hyperthreading as of yet and the i7 would be a waste. Some people will just go out and buy one anyways just to say that tey have one and don't get me wrong it will work and work very well but you won't be using all of the features of the i7 cpu.

Take the Core i7!Awlays get the best you can or you'll regret it!
The Core i7 will overclock higher than the Core i5 and because of that it will also outperform it in single core tasks.And thanks to the multithreading you'll see a hughe FPS increase in Multiplayer games such as Battlefield 3.

You will NOT regret buying the Core i7.

Here is a review comparing the performance of an overclocked Sandy Bridge CPU vs a overlcocked Ivy Bridge CPU

There is no benefit in gaming of a i7 over a i5 except in 1 or 2 games that actually use hyperthreading. There is no benefit in overclocking of a i7 over i5 either.

I didn't even think that there were any games that use more than two cores.

BF3 and Dirt 3 are two that I know for a fact do, but there are at least a few others (like Civ5, I think).

Ok so we are up to what three or four cores? That's still just a regular i5 quad core and not needing hyperthreading.

Definitely agree with that. HT is actually detrimental in some games, anyway.

MANY games use 4 cores. In fact some perform horribly if you don't have 4 cores.

Yea. Well, games aren't really coded to know what HyperThreads are, let alone how to use them. There is rumor that BF3 knows how to use them, but its not really necessary, and if it is true, it stands alone in the sea of games.

Skyrim I can say, it uses 2 cores heavily, and occasionally spawns 2 more cores and uses them lightly. (Thats my experience with it on my rig playing it at Ultra settings 1280x1024). so a strong dual core like an i3 handles it just fine in most resolutions. Skyrim is a console port and the shadow rendering per techspot is handed off for the CPU to do.

And as you can see, as is consistent even in quad core utilized games, HyperThreading has no real impact on performance. (3FPS, which is well within margin of error)

There may be in the background while a game is playing processes open and running and if there are enough then they could be utilizing additional cores.
There were times when I had a second screen connected while playing a game and the resource manager open displaying the cpu usage on the second screen. I have a six core i7 with hyperthreading and in the resource screen the cpu usage showed activity on 8 or 9 cores. The game being played was call of duty mw2.

Yea, thats what I meant in my poorly explained "Within the margin of error" comment, its a your mileage may vary sort of thing. All of the COD games are definitely dual core though, they have no idea what HyperThreads are, but your Windows OS does.

That's Windows doing that. The game isn't using 9 cores.

I realize that but I was trying to say that with the game running Windows was utilizing the extra cores that were available and the result is no interuption in the game because of processes running in the background which some people shut off so they have no drain on resources.

Activity on all cores does not necessarily mean that an application is using that many thread. You can have a single-threaded application show activity on 8 cores/threads simply because the OS' scheduler is bumping the application from core to core frequently enough to make you think it is multi-threaded. In this case, if you add up CPU usage across all cores for that application, you end up with a total equivalent to a single core at 100%.
