The GT200 was far faster than the RV770 - so of course by putting two on a board you're still going to have a faster board. It wasn't faster because of the quality of the power hardware.

The rev1 GTX295 had extremely slim profits for nVidia - that's why they spent money making a rev2 (which had the same performance).

Back on topic - this card will sell well unless it starts failing. nVidia might have underestimated their OCP - and sure if the card can't handle overclocking it's a bad thing, which for me at least would tip the scales towards the 6990, but if you overclock you void your warranty and bear the obvious risks of overclocking anyway.

I'm sure there'll be some third party boards out soon if their is a big problem - or even a whole new design from nVidia.



Good point. I forgot about the earlier ones.
There are no rose colored glasses donning my face.

True the 295 dominated because a 275 > 4870.

Now we have the same scenario, a 580 > 6970

But in this case 1 x 6990 > 1 x 590.
What happened, cheaper components.
I'll say it again the 590 is a step down to what NV did with the previous gen of their dual gpu card.
The rev1 295 did have superior components, they could overvolt and overclock 30% and greater.

And once again I'm not making any hw comparisons to the ATI side, just to what NV did with this gen dual card compared to the last gen.

You've forgotten heat outputs. The GTX295 drew far less power from the wall than the latest cards - making it far easier to cool. The 295 was cut down from the full core as well - it was two GTX275s at heart, rather than 285s. This also reduces the thermal output.

Sure, nVidia have cut down on this one - but saying 'they don't do them like they used to do them' simply isn't sound logic in this case - the power circuitry does not determine the overall performance when there's so much heat. Sure, if this is unstable then it'll hinder it somewhat - but when you've got 365 watts being emitted at OCP full load (the GTX295 emitted 289 watts) then it's all out the window - as long as you don't want a noise rocket.

Personally, I'm not looking at overclocking here - since it's not what nVidia's designed them primarily for (clearly, looking at the power hardware).

But you know ... having a GTX 590 gives you some kind of "status" ... people just don't care how bad it sucks ... they just want to show that they have the 590 ...

and most of 590 users try to show how much they really understand about graphic cards ... but in the end ... if you show him a mosfet & a memory chip ... for him ... they are the same ...

So... what the hell ... ( attention ... i'm just criticizing some "way of life" that some users have ... you can buy a 590 for your delight of course ... )

By the way, Cepheus ... the power circuitry will determine performance ... of course!!!! if you have a good vrm design, your power draw can lower, your temperatures will lower due to lower vrm load ... so ... all this will will determine overall performance of the card!!!


Edit: I was not finger pointing to anyone with the first part of the text ... it's just a thought i have after reading so much bs trying argument how good the card is ... even if it's built like crap ... the only good part of that card are the GF110 chips ... poor chips ... Having a dual GF110 fully unlocked card and not being able to use them ...

And yes ... i've always been a nvidia user, before you start thinking otherwise ... don't know if i will keep with Nvidia on this generation though ...

Think what you want, the 590 is not a quality build.
The 590 is a marketing teams dream, quieter, shorter than the competitors offering.
Doesn't live up to an enthusiasts dream at all, NV recommends only 25mv oc.
The stigma of the GF100 laid the foundation for this poorly constructed card.

I don't care what NV wants, in reality they should want what the majority of their enthusiasts fan base wants.
Damn the heat, damn the noise, give us a card capable of trouncing the 6990.

This card has so much potential if the components supported it.
I'd even think about buying it if this thing was bomproof.

Speaking of logic, where's the logic in making this card and then failing to properly control the power consumption.

But we're just going round and round about nothing.

I just think this card is a let down knowing what NV is capable of.

Every single card to date has been an excellent overvolter/clocker, minus the cost cutting co op 290 and the 590.

Give me a dual pcp 590 with bombproof components any day over this gimped attempt at an enthusiast card.

Mr Jensen once said we won't do a dual gpu card unless it's the performance leader, wonder what he's saying now?

Nvidia basically needed to put out a dual GPU board that killed the performance of the 6990 at stock with the OC head room of the GTX560Ti. Had they done that, it would have been an epic win. As is, it's a major fail.

Got to be temporary while they line out the OCP, It's obvious they can't use a static OCP because that would hinder too many games.

I mean you know, COD needs less than M2033, etc..

Nvidia are notorious for having more expensive cards so to me it's seems they skimped on parts to maintain profit while remaining competitive. It really hasn't worked out in there favor.
