Did I make the correct decision?

post #1 of 8
Thread Starter 
Hi all, just would like to hear some opinions on these 2 processors. When I upgraded I was originally going with the i5 3570k due to most people saying hyperthreading not needed in games. But there was a sale for an i7 2600k for roughly the same price (within $10 of each other) so I returned the 3570k and got that bad boy. I am happy with it, but I would have been happy with the 3570k also. Which cpu would you have gotten in that situation? This is being used mostly for gaming.

My reasoning was that in the benchmarks I saw, that pcie 3 had up to a 5% difference, and hyperthreading had up to a 15% difference. So when these 2 technologies did make a difference, I went with the one that seemed to make a bigger impact on performance. Your thoughts? Opinions?

For gaming I would definately go with a i5 3570K.

When it comes to multithreaded games, if it is coded for multithreading will that take advantage of hyperthreading automatically, or is hyperthreading something that needs to be specifically coded for?

Gaming is heavily reliant on the video card. The CPU does come into play, but it's a smaller part from generation to generation.

 

You're fine with a i7 2600k. My only worry would be if you planned on keeping that chip for a while and go to upgrade to a newer video card that will not function at full potential on PC-E 2.x and requires 3.0. But that might be a long while lol.

The i7-2600k is a great chip and you should be able to oc the heck out of it. I love mine.
Did you get a Z77 mobo? I think there may be more than just pci-e 3.0 features that you will miss out on if you did.

Yes I did get a z77 mobo and was too lazy to take my comp apart again and exchange it for an older gen mobo. Besides pci-e 3.0 what features did you have in mind?

From VR-Zone:

•Lower power consumption thanks to 22nm Tri-Gate Die Shrink and other tweaks
•Up to double the 3D integrated graphics (HD 4000 IGP) & Quick Sync video performance
•Ultra high resolution (4K) and multi-display (triple) support
•16 PCI Express v3 lanes (double the sustained per-link bandwidth)
•Hardware Random Number Generator - improved security
•Improved memory controller (DDR3-2800+)
•More overclocking with less effort - realtime adjustments and higher multiplier limits
•New 7-series chipsets with native USB 3.0 and (optional) Thunderbolt support

Only the Quick Sync improvement seems like a reason to pick Ivy over Sandy. Although Thunderbolt use could be nice.

You'll be fine with a 2600k, I was in the same situation and opted for a 2700k that was on sale. Ivy is a tick iteration in intels business model of releasing CPU's. It is essentially a die shrinked sandy bridge CPU. You aren't missing a damn thing other than significantly more powerful igpu but who uses igpu if you're a gamer lol? The only forseeable problem I can see is in a year or two when the new GPU's come out you may find yourself hitting bottelenecks if you plan on SLI/ triple SLI especially but for now you are perfectly fine and imo it was a reasonable decision although I personally would have probably just stuck with a 3570k at this point.

Either way you will be happy and if you are a guy who prefers 1 single very strong GPU solution which is actually better if you enjoy competitive play because SLI introduces input lag anyways you'll be fine for 2-3 years I would say. I can't see a X16 PCI-E slot getting bottlenecked sooner than that.

In the future just be conscious that if you are planning on doing a strictly gaming rig than HT is completely unnecessary, however if you do things like photoshop, video encoding/editing etc etc. Things that actually benefit quite a bit from HT then go that way. However if you are 80% plus just gaming on your PC HT is really a waste of money largely I find. Don't always think 2600k>2500k or 3770k>3570k because for gaming that simply isn't the case ;p.

You will be perfectly find though so don't worry about it man, enjoy your new rig and have fun! That's what I would do biggrin.gif
What this guy posted is largely a load of bologna, USB 3.0 is supported on the Z77 chipset natively, the CPU is irrelevant and anyone who is running faster ram is seeing MAYBE 2-3FPS difference in real world gaming scenarios, 1600MHZ is perfectly fine for gaming and should be for the forseeable future. Anyways Sandy can support up to 2400mhz iirc which will be plenty fast for quite a long time.

Forgive spelling/grammar/syntax error, i'm drinking and tired tongue.gif

EDIT: Actually if you look at the link he provided though you will see that ivy bridge is only slightly better, we are talking like <6%? According to those benchmarks, so don't sweat it!
