Leaked slides claim to open NVIDIA's GTX 590 cookbook

The rumour-vine has moved on from delivering fruits, to presumably leaked slides claiming to contain the secret formula of NVIDIA's ambrosia - the GTX 590.

mmmmm, I want one

[WhiteNoise]

F dual cards. When is the next series coming out.

[toaster]

Meh.. I've had my run with a dual GPU setup. Not my cup of tea. I'd rather get the best single card solution I can and then just upgrade to the next gen when it releases.

[earbus]

Still amd 4 me.

[Caleb_141]

Are dual-GPU's really that bad though? I've got a GTX 295 and haven't really had any problems with it to be fair... I'm intrigued to understand why though? Is it just because they use SLi which causes the problems?

[Thrillhouse]

Yeah, SLI and CrossfireX (which is what dual-gpu cards are seen as by the system) can still be pretty iffy with certain titles, especially with things like micro-stuttering. The extreme costs are also a turnoff for people.

But when they work corrently, it's beautiful.

Dual-cards can have some inherent problems much like SLI or Crossfire set-ups, although the severity of such problems ranges heavily from user to user. Two people may have the exact same set-up but one may experience issues whereas the other may not, or have less issues to the point where it's not noticeable.

A common problem can be microstuttering, which is caused when the 2 GPUs either in a dual-card GPU or an SLI/Crossfire set-up fail to synchronize properly, causing spikes from a high FPS to a low FPS in quick succession. Although a FPS monitoring program may show a stable FPS the user will experience stuttering. Pretty much all dual GPU set-ups have this problem, but you may not notice it depending on the system.

Also you have to deal with profiles like you would using SLI or Crossfire, which can cause problems depending on the game and how well it was coded to make use of dual GPUs. Some games may actually produce negative scaling, so getting worse performance than if you were using just 1 GPU, we call these games "useless rubbish".

But no, dual cards don't really have any more problems than 2 separate GPUs, and can sometimes be less prone to certain problems due to latency issues. People tend to avoid them in favour of a single card solution if say they've used dual cards before and had problem, which they then wouldn't recommended to others, or if they've read about the problems on some tech forum and don't want to risk the headache themselves. Also they can be very power hungry compared to a single card with equal performance.

I, myself am currently running 2 cards in Crossfire and apart from a couple of games, I've had little to no issues at all and have seen some great scaling, but others may not be so lucky.

I'm running two HD 5850's in crossfire and I have zero microstutter. Just lower the refresh rate of your monitor to 60 or 50 if you can and make sure your games run higher than 60 fps also use a mobo with x16 + x16 or x8 + x8 PCI-e slots. x16 + x4 = BAD news for you. Plus overclock your North Bridge.

590 GTX = $800
