Re: What are your thoughts on the GTX 680? Yeah, it looks like the 680 has three times the cores as the 580, although they run half as fast, if I understood the Tom review. So you're looking at a theoretical 33% boost in performance over the 580, before you get into the Turbo-boost-type technology Nvidia has integrated. A quick glance on the bar charts shows an up-to-32% gain on the GTX 580.

 DarkLogixTexan and ProudPremium join:2008-10-23 Baytown, TX kudos:3 | Any idea on if it actually utilizess the PCI-e 3.0 extra speed? I ask because for sometime now people have claimed that except for dual gpu cards nothing made full use of PCI-e 2.0 x16.
as I currently have a GTX570 I'd have to consider if the gain will be worth it or not. |

PCI Express 3.0: One Last Perf Point
GeForce GTX 680 includes a 16-lane PCI Express interface, just like almost every other graphics card we’ve reviewed in the last seven or so years. However, it’s one of the first boards with third-gen support. All six Radeon HD 7000 family members preempt the GeForce GTX 680 in this regard. But we already know that, in today’s games, doubling the data rate of a bus that isn’t currently saturated doesn’t impact performance very much.
By default, GTX 680 runs in X79 at PCIe 2.0 data rates

Enabling PCIe 3.0 is achieved through a driver update.

Nevertheless PCI Express 3.0 support becomes a more important discussion point here because Nvidia’s press driver doesn’t enable it on X79-based platforms. The company’s official stance is that the card is gen-three-capable, but that X79 Express is only validated for second-gen data rates. Drop it into an Ivy Bridge-based system, though, and it should immediately enable 8 GT/s transfer speeds.

Nvidia sent us an updated driver to prove that GeForce GTX 680 does work, and indeed, data transfer bandwidth shot up to almost 12 GB/s. Should Nvidia validate GTX 680 on X79, a new driver should be the answer. In contrast, the data bandwidth of AMD’s Radeon HD 7900s slides back from what we’ve seen in previous reviews. Neither AMD nor Gigabyte is able to explain why this is happening. -- If we lose this freedom of ours, history will record with the greatest astonishment, those who had the most to lose, did the least to prevent its happening. |

 DarkLogixTexan and ProudPremium join:2008-10-23 Baytown, TX kudos:3 | so what you're telling me is I need to get the following later this year
dual Ivy-E xeons, GTX680, larger SSD, and even more ram. |

 DarkLogixTexan and ProudPremium join:2008-10-23 Baytown, TX kudos:3 | Well the SSD par tis due to being at about 75% full and I want more space on my speedy OS drive for programs to be installed.
Dual Ivy-E because its awsome
Ram, well if I did dual Ivy-e's then I'd have eight memory channels to fill with 4gb sticks |
