Best CPU for single GPU gaming? 2600k vs 3930k vs 3770k

post #1 of 19
Thread Starter 
Hi,

This is a very tough choice atm what with 3770k having reported heat problems which will reduce max OC when compared to SB.

I am thinking of grabbing a golden 2600k (5ghz@ <1.4v) off OCN and chucking it in a Asus P8Z77 Deluxe as I just don't see myself needing PCI-e 3.0 for a 680gtx@1080p. Pretty sure the 680 doesnt even support pci-e 3.0. I have the money for a 3930k upgrade however I remember seeing some benchmarks showing the 2600k being slightly faster in games, not to mention MUCH cheaper and better overclocker in most cases.

Games played will be GPU dependent such as BF3, Crysis2.

Will VIRTU-MVP be compatible with SB cpu? If not, am I losing out?

Thank you,
A confused consumer

Virtu MVP will work on any CPU, it just has to be a Z77 chipset motherboard to support it.

For gaming I don't see why you need an i7. 2500k or 3570k is all you would need and with an overclock your CPU isn't going to bottleneck anything at any res. Even if you have a game that loves multithreading like BF3 or whatever, an i5 overclocked will not bottleneck. In my experience a 2500k at 4.7ghz lets 580 SLI @ 900 core stay at 99% utilization in BF3 and I think I got around 75% CPU usage. If you are set on getting an i7, 2600k is the way to go but it's pretty overkill for gaming. If you do tasks that require high CPU throughput and take use of all 8 threads then go for it but you can't go wrong with the i5.

And if you're jumping ship to a new platform why don't you consider the i7 3820 wink.gif Should OC better on air than Ivy Bridge from what I've seen and don't be tricked into thinking that even though it isn't a K SKU that it can't OC well. X79 is a solid platform and you get two full x16 PCI-E 3 lanes at your disposal for the future, and then you're looking at Ivy Bridge E support as well. Unfortunately no MVP support though, but do you need it with a 680 at only 1920 x 1080?

For games only I'd buy a ivy bridge processor that doesn't have temperature problems. You don't want to stay at sandy bridge forever! Though a golden 2600k does sound nice you can have some next generation technology processor that can overclock higher. I have a 3930k at 4.6 ghz right now and its a decent overclocker, I've never been on 1155 so I can't say it's harder, but from a lot of people on 5ghz (or higher) 2600k, 2500k, 2700k overclocks it seems that it's slightly easier. It's most likely easier to overclock because of the 2 less cores. Less vcore needed and less heat. Anyways the 3930k may not have as high single core clock speeds but it still delivers the same gaming experience. The FPS difference is so small, like 1 fps difference. I would go SB-E because you have higher potential of power compared to LGA 1155 processors when it comes to overall tasks. Also Ivy bridge E is going to be supported on LGA 2011 so you can get an upgrade then.

If you have the money for a 3930k, then i would say go for it. It will last longer than a 2600k/2500k. Plus, 680 won't be using pcie3 but future gen cards will and then, you won't regret having a cpu that doesn't support it. Also the quad channel memory and 40 pcie lanes will help when you will sli later as one card won't be enough.
So in short, 2500k or 3570k may seem like a good investment now but in the long run, a 3930k will last you longer and prove to be cheaper.

For gaming only you won't notice the difference between a 2500k and any of those CPUs.

I could have afforded to get a better CPU as well but after a lot of research (Keep in mind the only difficult task I do is gaming) I couldn't find a logical reason to go with a more expensive processor.

And the thing is you can find them as low as 150 bucks and there it's a steal. Pair it with a real nice mobo and that 680 and you got a machine that will max out games til the next consoles come out. Buying a 6 core will not help you now in gaming and by the time the next consoles come around and games take a big leap it will probabally be outdated.

Just my two cents.

Previously i had a 2500k, then a 2600k... And really didn't saw a difference for what i do (gaming, web browsing, normal stuff)... That was with a GTX570
So this time i'm going with a 3570k (but i'm waiting some months for a better revision) thumb.gif

Building my new PC, when I saw this on sale today.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813131808R


Got one before it sold out. Didn't have time to think about it for long, so hope I don't regret it. Was planning on going 2011 socket for the many reasons named above, but hadn't decided on a mobo yet. This Asus Rampage IV F looks good in general.


Anyway, I think if you are building right now, and you have the extra few hundred to spend, go 2011 socket with the $300 chip, spend the rest of the budget on GPUs and monitors, and grab an IVY-E next year, or whenever they drop. That is my plan anyway.


Now, off to pick a cooler.

3820....

*same price range as 2600K
*More powerful than the 2600K
*Can upgrade to 3930K later (as you have the socket)
*Longer life (LGA 2011 will outlast 1155 and we still have IB-E to come)

The only downside is you get slightly less bang for your buck in the motherboard stakes. But for the extra £50 or so an LGA 2011 board will cost, you get the peace of mind you can still upgrade your PC later and still have Ivybridge-E to look forward to.

But like most people here the OP sounds like he doesn't want a CPU unless it has the 'K' suffix, seriously guys they are good chips but not the be all and end all. I have my 3820 OC'd to 4.75GHz stable which is higher than most 2500K's will go despite being "unlocked and unleasehed" which mine apparently isn't.

Yep, exactly what I did.

I haven't specified future proof as a requirement. The single core permanence of the 3930k is lower than all the processors mentioned above. Almost all of the games I play only use up to 4 cores, so my only concern is the maximum possible single core performance on 4 or more cores when overclocked to the bleeding edge.
No Budget
No future proof
Pure performance

I am thinking a 3770k on Phase at about 5.2Ghz, I've seen phase used in 24/7 configuration. Sounds like a lot of fun.

Thoughts?
