2600k or 3770k?

post #1 of 30
Thread Starter 
I plan on building another PC. My question is, should I wait for the 3770k or stick with a 2600k? Is the upgrade to PCI-e 3.0 that big or noticeable? I plan on getting a 7970. Would it be worth it to get a cheap Sandy bridge chip until Ivy Bridge comes out? Thanks in advance.

This is exactly what I plan on doing on my new build. But in this article it says ivy is only 10% faster http://wccftech.com/i7-3770k-i7-2600k-benchmarks-surface-ivy-bridge-10-faster/

The point is not that is 10% faster clock per clock. The point is you should easily be able to reach 5GHz, even 5.5Ghz or 6.

A 5Ghz should be commonplace, while 4ghz is common for any current SandyBridge.

i would wait for IB and combine it with a z77 mobo
PCIe 3.0
native USB 3.0 which means dont need an USB 3.0 controller
native RAM upto 1600MHz
x63 multipler so should be easier to go 5GHz + thumb.gif

I would definitely either wait for Ivy Bridge or get a cheap Sandy CPU and upgrade to the 3770K when it comes out in a couple months.

We don't know how well Ivy Bridge is going to clock, but I suspect desmin88's projections are a little too optimistic. I would tend to say that 4.5 or 4.6 GHz is common for any current sandy bridge. I suspect that Ivy Bridge will improve things a few hundred MHz, perhaps so that 4.8 or 4.9 GHz will be common. I don't think we will see the grand 5.5 GHz clock speeds that some people are predicting. 3D 22nm transistors are probably more aimed at reducing power consumption at a given clockspeed than improving absolute clock potential.

Nonetheless, if i were looking at an LGA1155 system, a few hundred MHz extra clock potential, lower power consumption, and ~6-7% higher IPC would probably be worth waiting for.

IMo 10% is a lot of improvement for what it is.

So the general consensus that I read is wait for Ivy Bridge. About the Z77 mobo, is it really that much better than an ASUS P8Z68-V Pro GEN 3? What does the newer chipset offer? Is it worth it?

pretty much this Native RAM support

513

and Native USB 3.0, there could be more

Exactly stubass, that's whats been confirmed. There were also reports quite a while ago that Z77 and Ivy Bridge would feature CPU strap ratios similar to X79 and Sandy Bridge-E. I think the report was that there would be a single additional 1.33X strap ratio, allowing the use of a 133 MHz baseclock. That's really rather inconsequential if you're purchasing a K series chip though.

interesting, also i think 2.5x strap ration of SB-E and the I7 3820 released in 2- 3weeks allowing for the chip to be OCed to 4.8GHz makes for a nice budget SB-E rig smile.gif
