Should I wait for Gtx 680?

Okay so I am building a gaming rig and was previously going to buy a gtx 580 for it but after some thought I realized the gtx 680 would be coming out very soon. Should I just wait or what? And also do I need a ivy bridge CPU to run with a pci-e 3.0 card or can I just run it with a 2600k?

More about : wait gtx 680

If I were you I would wait for the Kepler series (6 series). It is rumored that they will be coming out this month. I'm waiting as I have a gtx 285 and was wanting the 580 as well. If series 6 comes out soon enough you can either buy that or hopefully catch a deal on the 580.

Wait only if you're prepared to pay over $500 for the GTX 680. Meanwhile, the GTX 580 is down below $400. With a release date on March 23rd for the GTX 680, your best bet is to wait and see what happens.

Not sure where you are seeing your 580's for 400 but most I see are in the 450 range

The anticipated price for the 680 was $650

http://www.tomshardware.com/news/Nvidia-Kepler-GPU-GeFo...

Id also say might as well wait .... but I won't be waiting for the 670's and 680's .... not when twin 650 Tis are likely to blow their doors off. Looking at the current generation cards.....

The 580 gets 616 fps for $450 ($0.73 per frame).

Two 560 Ti's get 862 fps fps for $440 ($0.49 per frame).

That's 40% more fps for less money !

Well ya can add another 580 ya say ?

2nd 580 gets you 953 fps for $900 ($0.94 per frame) ..... 10% more performance than the 560's for more than twice the price ???

I'd buy two 560s for the same reason I built w/ a 920 and not the 980 .... way to low an ROI (return on investment) for my money.

Yeah the Gtx 580's that I have been seeing have been at least $450 so i thought I might as well pay another hundred for top of the line. Can someone answer the second part of my question? do I need a ivy bridge CPU to run with a pci-e 3.0 card or can I just run it with a 2600k?

I don't think this is cpu related it is mobo related. Most mobos now days have 3.0 slots.

It is CPU related. Even if you have motherboard with PCIE 3.0, you need an Ivybridge core i5 or core i7 or a Sandybridge Ex to use its speed.

I have a GTX 580 on Newegg for $410. Apparently, the sub-$400 I heard about was in Canadian currency... oops. I still think that price is coming down even more after the GTX 680 comes out.

Jack (and anyone else), time to cruise this thread for updated information on Kepler, $550 on March 23rd:

There is no need to upgrade specifically for PCIe 3.0 vs. PCIe 2.0. A 2600k PCIe 2.0 will work just fine:

Okay wait, I'm a bit confused. So if I have a sandy bridge 2600k processor in a moterboard that has a 3.0 pcie slot, will that slot be obsolete (meaning it won't work)? Or will it just work at 2.0 speed? So say I have a 3.0 motherboard with a 2600k installed and I add a gtx 580 to one of the 3.0 slots, will it work or not?

Is Ivy Bridge out yet ???


It will work fine at PCIE 2.0 speeds. And in my opinion these new architectures from nvidia and amd should not take advantage of that new speeds (maybe next gen). Ivy bridge is not out yet. Only a few test samples: The Ivy Bridge Preview: Core i7 3770K Tested.

Okay so tell me if I'm right. I put a 2600k on a 3.0 mobo. Then I put put a gtx580 in that 3.0 slot. The gtx580 will work but it will only be at 2.0 speeds. Am I right?

Sorry I just want to be for sure.

Yes. But GTX580 uses max PCIE 2.0 anyway :p .

+1.

Imagine that people using two cards at SLI or XFIRE by sharing one 16x PCIE 2.0 to x8 x8. Which means each card uses PCIE 1.0 speeds without probs (scaling up to 100%! in some cases). Hell I use a gtx570 in PCIE 1.0 without performance loss (maybe 1% :p ).

However there is a usage for these speeds mostly for PCIE SSDS like Revodrive 4 from OCZ or professional gpus that use the high badwinth for some programs like AUTOCAD.

While there isn't a lot of need for it now, if they don't release PCI-E 3.0, then hardware manufacturers and dev's won't find ways to take advantage of it. 3.0 is not of value now, but it does pave the way for the future.

I wouldn't call it marketing bull, as it does need to take place for future advancements, but I wouldn't worry about buying it for today.
