From i7-2600k to i7-980?

post #1 of 12
Thread Starter 
In short, should I go from my i7-2600k to an i7-980?

I'm an architecture student so I use a lot of CAD programs along with a slew of 3D modeling programs such as 3DS Max, Maxwell Render and Kerkythea, so I'm wondering if a hexa-core processor would provide an increase in performance that would justify the switch and the cost of doing so.

The i7-3930k is out of my price range (I'd be buying the 980 used) so the 980 seems the more economical route, though I realize I'd have to purchase an new motherboard to accommodate the 1366 socket.

Thanks ahead of time smile.gif

Nope. Stay with the 2600k as the 980 is an older architecture and older socket, which will not allow you to upgrade.

The extra cores and threads are always a plus when putting your machine to work like that, but is it enough of an improvement for its intended purpose? Hard to believe a 4 core 8 thread 2600K can't hold its own with the software you intend to use it for.

Only CPU worth upgrading to is the i7-3960X.

For those uses a 980X is definitely a better CPU than a 2600K and X58 also offers you more flexibility with stuff like pci-e lanes, but in the end I'd say it comes down to price. How much would you be paying for the 980X? getting it for much cheaper than a 3930K seems like a stretch, or you're getting one hell of a deal.

Alternatively you could go and look for a used i7 970, because I'd figure those should be really cheap nowadays if you can find one. And they still OC just as well as a 980X, you just have to use the bclk.

And considering how high the base multipliers are on them, they still have one heck of a potential!


I've seen 970s go at $300 on eBay. Which is on beast of a deal. You can get a killer 1366 rig with $500 (CPU+board+RAM) if you search for the right deals.

I would try to overclock the 2600K, since its a newer architecture clock for clock its faster than the previous i7s so if you overclock it some more you can make up for the extra cores, on top of that the 2600K runs much cooler than the 980X.

I think the 970 has been replaced by the 980. I'm guessing that's the cpu he intends to buy, and not the extreme cpu?

It's not that my 2600k is slow by any stretch, I was just wondering if the performance increase would warrant the switch. If it saves me 5 minutes on each of 10-20 test renders while working on an image, that time saved really adds up, and architecture is all about deadlines wink.gif

I have a friend locally that offered me one for $385, otherwise he was going to set it aside and use it in another build. That price seemed low enough to wonder if the switch was worth it, seeing as I'd sell my 2600k and current mobo to offset the price down even more.

The 2600K is faster per core but what is most definitely is not is faster clock for clock.

Also the chances of hitting 4.5ghz+ with a gulftown are pretty much similar to hitting 5ghz+ with SB so the clock difference wont even be that big. There's pretty much no question that for OP, 6cores > 4cores.

That's a pretty epic price. I would most likely go for it in your situation. Just check some more detailed benches of the specific programs that you use before pulling the trigger, but the difference should be pretty clear smile.gif

Yes, it would be a i7-980, not the 980x.
