Concerns of G92 + P35 (or other current chipsets)

[asdftt123]

I'm going to be purchasing a new desktop system in September because my current 4-year old Dell laptop is close to the verge of death with its overheating issues and constant crashing. Since I haven't had a good system in awhile I want to make a really good gaming system that will last me for years.

For me, it feels like a very awkward time to purchase a new video card. Not only is the current series of high end cards severely overpriced, but the G92 is going to be released in about 3 months. I'm pretty much set on my current system consisting of Quad-core Q6600, 4GB DDR2 800, 8800GTX, but the current performance of the 8800 series on DX10 is very discouraging.

I want to be able to upgrade to the G92 series when the time comes around but I'm concerned that it won't run optimally with the current P35 chipset since it only supports standard PCI-e. I know the x38 is around the corner but other than PCI-e 2.0, I don't care about CF/SLi, or DDR3 support. I also suspect the board will be very costly upon release since it's targeted towards enthusiastic gamers.

My questions are:

1. Will the G92 series work with standard PCI-e 1.0? Logically, Nvidia would be completely out of their mind to make it strictly PCI-e 2.0 because PCI-e 2.0 isn't even currently available on current mobos resulting in horrible holiday sales.

2. Is it possible that current PCI-e 16x or any other components of my build will bottleneck the card?

3. Should I plan on purchasing a bigger PSU for the upgrade? I currently have the Corsair 520HX, but should I get at least 600 or 700W?

3. Finally, when will Nvidia release more information and specs regarding their card? It's driving me nuts, at the moment.

Thanks for your help!

Yes, it will:

The PCIe Base 2.0 specification supports both 2.5GT/s and 5GT/s signaling rates, in order to retain backward compatibility with existing PCIe 1.0 and 1.1 systems

The PCIe Base 2.0 specification supports both the 2.5GT/s and 5GT/s signaling technologies. A device designed to the PCIe Base 2.0 specification may support 2.5GT/s, 5GT/s or both. However, a device designed to operate specifically at 5GT/s must also support 2.5GT/s signaling.

2. Is it possible that current PCI-e 16x or any other components of my build will bottleneck the card?

It may be theoretically possible, but highly doubtful. PCIe 16x MAY bottleneck multi card video setups (think more than two), but even that is unlikely. Then again, if you can afford $1000+ in video cards, what's a new motherboard?

3. Should I plan on purchasing a bigger PSU for the upgrade? I currently have the Corsair 520HX, but should I get at least 600 or 700W?

Tough to say... A high power/quality PSU is never a bad idea. However, some are speculating that G92 may actually consume less power than G80 because it should really be more of an evolution of G80 (including a shrink), as opposed to a brand new architecture. New architectures tend to run hot and consume a lot of power, whereas refinements tend to be more efficient. What the actual requirements are, only NVIDIA knows...

3. Finally, when will Nvidia release more information and specs regarding their card? It's driving me nuts, at the moment.

When they are ready for you know...
