Is thier any talk of a dual gpu solution of this generation?

Even if there was it would take at least 6 months for anything to happen. The only reason there was a GTX295 was because of the die shrink. With 40nm currently used with GTX480 they will need something lower like 32nm.

This. If there ever will be a GTX495 do not expect it anytime soon. For now if you want a dual DX11 GPU ATI is your only opinion, with the 5970 and the rumored 5950.

Well then Ill probly go dual 480s then, cause im sure the 495 would only be a dual 460 basicly.

More like dual GTX475, just like the GTX295 wasn't dual GTX280 or dual GTX260 but dual GTX275. But you are right just like two GTX280's beat a GTX295 if history repeats itself which is highly likely the dual GTX480's will beat the GTX495(If it ever comes out that is).

The GTX 480 gives off a little too much heat and they need shrink it down a little. x2 cards normally come out a few months after the card has come out.

Maybe a GTX295 will be the fully unlocked Fermi, 32nm(28?), with decent clocks?

Skipping over dual GPU

maybe. 512 shaders is TON!

I don't see how this can be possible for a lot of reasons. For one the GTX 480 is using a new 40nm process, so nvidia would need to shrink it further to fit that massive beast on one pcb. 32nm is what would be needed for nvidia to even talk about a 495. Furthermore the PCI-E wattage wall has already been dangerously teased; the 480 runs at 295w, the limit is 300w. Putting two of these power hungry beasts on one PCI-E lane would light your motherboard on fire.

And, lastly, heat is a huge factor. The 5970 has a lot of heat issues with the stock cooling and runs 60% cooler than the GTX 480 will judging solely on the 295w usage. Imagine what two 480's would be like heat wise?

Hence my suggestion it be the 32/28nm 512SP monster Fermi was supposed to be

Does the pci card pull power off the slot? I thought thats what the power connectors were for from the PSU.

Yes, the first few connectors in the PCIe slot supply 3.3V and 12V power.

Upto:

PCIe1.x = 75W
PCIe2.x = 150W

If I was to do dual gtx 480s and a 295 for gfx am I looking at a 1200w power supply? Or would the corsair 1000w run it? I cant afford the sli GTXs yet but need a power supply now and want to future proof it.

Did you just say dual gtx480 and gtx295 for physx? Nuts man, nuts... You're probably going to need a small portable gas powered generator for these things. From the sound of it if they release too many of them we're going to have brown outs in certain cities... lolz

In the eVGA forums, we figured out a GTX295 cannot be selected by the drivers for dedicated Physx - also, CUDA (and by extension, Physx) only works with one GPU core at a time. You cannot SLI CUDA cores
(yet)

Wonder if in the future that will change. Maybe I should sell my GTX 295 if I cant use it for physics. I am looking at the Enermax Galazy 1250 watt.

And I am still throwing around the idea of 2x 295s or sell the 295 and buy, 2x 480s...with a 260 for physx.

''GTX495'' is ''semi-accurately'' coming out in September this year.

History lessons:

No 1)GTX295 (55nm) came out in 8th January 2009. GTX260 (65nm) came out in 26th June, 2008.
Delta = 6 months (longer as involving a die shrink?)

No 2)9800GX2 (65nm) came out in 18th March 2008. 8800GTS 512 (65nm) came out in 11th December 2007.
Delta = 3 months (shorter due to no die shrink?)

Between now and then, ''GTX485'' (or named ''GTX480 Ultra'') with full 512 could ''semi-accurately'' come out as a refresh.

LOL

a 9600GT is more than enough for PhysX, i've actually seen benches where the best combo was a single GTX285 paired with a 9600GT for PhysX, got great results.

personally, a GT240 would be the biggest card you would want in a PhysX setup, not to mention its the most powerful single-slot card i think. which is a plus if its only there to do PhysX work.

2 more quarters...or even the end of this year.

doesnt ATI already use something like 32 or 35nm?
