GTX 590 Quad SLI tested - 4. Conclusion

Review:
Top Performance, High Price


GTX 590 is a Fermi based, dual-GPU and DX11 card that does well in fighting HD 6990, but there is no clear cut winner as of yet. Unfortunately, we did not have the results scored by two HD 6990 cards, so that we could compare quad GPU rigs, but we can at least share our impressions of the GTX 590 Quad SLI rig.

Our machine had two GTX 590 cards that will cost about €1200. We must thank Gainward and Point of View / TGT who have kindly provided us with samples.

As far as performance goes, we’ve never seen something this fast. However, although Quad SLI sounds cool, most gamers will do just fine with a single GTX 590. Single GTX 590 performance is excellent and two cards will only make what’s already fast, into fast-er.

We must say, extraordinary performance aside, €1200 for two GTX 590 graphics cards is a bit too steep, regardless of how deep your pockets are. Two GTX 590 cards will not double your performance because it seems we have history repeating. Namely, scaling performance with four GPUs is far lower than with two. We had some trouble with a few tests - 3Dmark 2011 Extreme and Metro 2033 running at 2560x1600 and 4xAA i 16AF. We think that the problems are simply down to unfinished drivers.

Quad SLI will not require only two GTX 590 cards, you must have a good 1000W+ PSU and CPU, because your CPU may limit performance.

As far as noise goes, two GTX 590 cards didn’t make much more noise than with one GTX 590. That our rig was loud is true, but it’s not unbearable. Nvidia did a good job with reference cooling, but you still need to have a well ventilated and roomy case. If the temperatures exceed 97°C, the thermal threshold will kick in.

All in all, we don’t have many complaints about GTX 590 Quad SLI; Nvidia did a pretty good job, and we enjoyed some 2560x1600 gaming for a few hours.

nVidia has some driver issues in Metro it seems..why would one GTX590 be able to use AA while two can't?

nVidia's better at lower resolutions with their top-tier cards than AMD is. Not sure if that's a good thing.. (http://www.hardwareheaven.com/reviews/1139/pg5/zotac-nvidia-geforce-gtx-590-quad-sli-review-bulletstorm.html)

Needs more games other than an AMD-sided game and an nVidia-sided game WITH tessellation.

They dont know how to make a quad sli review. Tests at 1920x1080? That is possible with 570 / 6970. It is retarded to use that settings with 2 590. I would say 2560x1600 should be the minimum resolution and that 3 monitor tests are necessary. When you use 3 monitors scalling of quad sli becomes much better. Also there was no comparsion with 3 580 or 3 6970 that would be faster.

2 x GTX 590
1200Watt
Cost over £1100
Lower performance than HD 6990
Might explode

2 x HD 6990
Under 900Watt
Costs under £925
Best performance
Doesn't explode

Nvidia need 28nm badly, AMD already in production of 28nm cards, rumoured release in July. The next round of cards will be amazing, the GTX 590 really isn't worth its price tag. Either HD 6990 or if want Nvidia wait until Nvidia hit 28nm..

in a direct head 2 head 6990 vs 590, ati scores on allmost every test..

real shame you couldnt buckle up 2x6990 in this comparison, it would basically all come down to driver tweaking to decide who holds the quad-scaling crown

either way.. i think testing with 3x2 monitor would be in place with those speeds... if you want true results and scaling up to like 7680×3200 resolutions

2x HD6990 still wins

It'll probably be just mobile series which were rumoured to be released first, makes sense since we're constantly trying to increase the mobile marketshare, we won't see the desktop HD 7xxx until Q4 2011

1099 Watts is pretty extreme for almost any purpose.

All the eye candy does not make an FPS player shoot better...
