Which GeForce 8800 do I get...

So it seems that the GeForce 8800's are now available to buy - something I've been waiting for for a while [grin]

Overclockers appear to have some stock of various models; the 'BFG GeForce 8800 GTS 640MB GDDR3' model for a mere GBP381.86 seems like a reasonable deal to me. The bigger and badder GTX's are just too expensive to be justifiable.

Can't say I'm overly fussed about performance - my 7300LE is rubbish and my 6800 isn't anything special yet I've not had many (if any) situations where its been too slow. Every benchmark I've seen puts all variants of the 8800 at well above either of those GPU's.

Now the big question. The really big question. The one that I want an answer to before I part with my cash: Will I be able to use it with Direct3D 10.

I'm using Vista-RC1 and the October SDK and it'd be nice if I could buy the hardware, drop it in and have a hardware D3D10 device to use.

Thing is, I fully expect driver problems - I see the '95' drivers are out for Vista-RC2 but they aren't compatible with Vista-RC1 due to DDI changes. I doubt out-of-the-box drivers for Nvidia GPU's will enable D3D10 and equally any archived RC1 drivers probably aren't G80 enabled.

So, the catch - I'd need Vista RC2 to use the hardware, but with Vista RC2 the SDK is not compatible. Bugger.

I would assume that the December '06 DirectX SDK will run on Vista RTM or RC2, but thats still another 5-6 weeks away...

I've asked in the official place, so maybe the powers that be will comment...

They sure are looking like some monster cards.

I can't wait to hear how your stuff runs on those. Be sure to fill us in when you get one :).

Right now there are no D3D10 drivers, I was reading the arch. review over at Beyond3D and this was one of the points made early on...

They certainly do look like monsters - people are talking about buying dedicated secondary PSU's just for the graphics now. Run a D3D10 game with SLI cards and you can go and watch the electricity meter spinning [oh]

Don't think I'll be getting one - based on what Ralf seems to know (yet to find any reason to doubt his info) there aren't any public D3D10 drivers.

If you buy a GeForce 8800 now then all you're actually getting is a turbo-charged D3D9 part with some disabled bells and whistles [rolleyes]

Hi,

For sure you will have to wait again for dx10 drivers :o(
Anyway, you can continue to develop with reference driver and hope it will run perfectly on new hardware when drivers will be available.
By the way, I always have a OUT_OF_MEMORY error when I try to create a Dx10 device. 6 months ago, on the same pc but with the SDK from february, it perfectly works. Did you notice some problems or do you have to do some manipulation to be able to create a reference dx10 device object ?
Thanks ans keep up the work !

Only if you're using DX. :) OpenGL extensions expose SM4 functionality even on XP, and then there's CUDA.
