so far not a good experience with my pc

Yeah sorry mate, i thought if you were using generic monitors then you could go eyefinity instead, but no tif they have the Nvidia sensor in them, apologies.

 

[keynes]

Feedback on the RAM appreciated.

 

[keynes]

From my limited knowledge I think that when playing in 3D surround, the higher the RAM of the GPU the better. Even if I have chosen to SLI a GTX 590, I am limited to only 1.5 GB as opposed to 3GB from the GTX 580?

 

[JakAttack]

Hi Ruben, the amount of VRAM you have only changes the texture loading primarily, as the textures will already be loaded and split across the 3 screens, this should not affect overall performance on 90% of games.

 

[keynes]

Thank you Jack. Any advice on what I should do in terms of the GPU? I do not wish to downgrade them and I am not sure that if an upgrade is a possibility (me paying the difference) to the GTX 590 SLI. But again I am lost on whether there are also issues with the 3D surround, I just wish the 3D features of the monitors I have to be fully utilised.

upgrading to a pair of 590's would probably result in a long wait, as i presume they are still like gold dust.

As for a suggestion on what to do it is a tough one. It can't be long before Nvidia finally get round to launching the 6xx series but who knows. They will probably come out with the 680 first if the mirror what AMD did, might be an option to hang on a little bit for those. Apart from that i can't see any way to swap to a different Nvidia card as they all have less VRAM....

I was hoping the GTX 590 SLI may give me the same or better performance for 3D gaming (which was the main reason for the purchase of the PC). Still puzzled on what to do, thanks for the advice though.

2 x 580's beat a single 590 as the 590 is underclocked slightly.

It really is difficult because of the monitors you have, waiting for the next gen cards from Nvidia is about all i can think of to be honest.

I meant GTX 590 SLI but your advice will still probably hold. The purchase was a birthday present (30 on Friday) and ideally I wanted the PC to be fully functioning by then, I am unware of the position of PCS regarding upgrading the GPU and as you mentioned waiting is an option but since release dates are not available it might be weeks or months.

 

[mantadog]

Yes it could turn out to be months as i did hear at one point Nvidia might skip right to the 7xx series. Getting a pair of 590's will be rather more costly than a pair of 580's, but would be one hell of a system indeed.

 

[keynes]

It will but if it guarantees a better performance for the 3D surround set up I do not mind paying extra, again if it is a possibility as well since I am still waiting for a reply from PCS.

The PC is going to be collected today and I was told my RMA will be treated as a priority. I think I'll stick with the GTX 580 3GB since I could not find any evidence that the GTX 590 SLI could perform significantly better and the GTX 580 1.5 SLI will underperform with games that require a lot of memory. My conclusion on this matter is that I have been unlucky with the build, I am pretty sure that PCS did their best during building and testing and the first issue with the USB ports not working and the last one with the fan controller malfunctioning may have been caused in transit and I was unlucky with the faulty GPU. A new rebuild was authorised and I was promised a change of components, technical support was always helpful and very polite when answering my queries even if I was very frustrated in some occassions. I am still happy to recommend PCS to anyone for their excellent customer support and prompt response to RMAs and I'll be purchasing again from them in the future. Thanks for everyone that contributed to my thread.

Not true, the only reason manufacturers release gpus with more and more memroy is because they know a p***ing contest will make people buy em and pay more for em. There is hardly any difference in performance between the 2. Put them side by side in identical rigs and the benchmarks will be almost identical give or take a few points, irrepsective of what games you are playing or number of monitors you are running.

 

[keynes]

Thanks for the feedback, I based my judgment on the benchmarks that I found online for the GTX 580 SLI vs GTX 580 3GB SLI
http://www.overclockers.com/forums/showthread.php?t=684954
It states that there is not much improvement between the 2 cards and most games (apart from some exceptions such as Metro) will not benefit from the additional RAM.
If you have to go with NVIDIA and it is a 3D surround, what GPU would you recommend?

 

[Maestro]

Interesting to see in those benchmarks that the 1.5gb cards in both sli and single score higher in over 50% of those scores. For this reason i would go with the 1.5gb cards.

 

[keynes]

I was also recommended the 1.5 by technical support as it seems they are more stable for 3D surround but I am unaware of why that is the case.

 

[Maestro]

As with all gpus some cards have more driver issues than others. This is why nvidia and amd release updates to the drivers on almost a monthly basis. If you look at the notes for new driver releases you will see that in a lot of instances they have sorted issues with particular games, and they also list known issues that they are still working on. At the moment it seems there are more gremlins in the drivers for the 3gb version than the 1.5gb.

 

[Grinder]

I read somewhere that 3 gpu's were a sweet spot for Sli.
Maybe 3 x 1.5's will give you the best possible performance for your rig .
If moneys no object .

 

[keynes]

I think it may be almost the same than 2 GTX 580 3GB but I am not sure the motherboard I have may support Tri-SLI or it will give a better performance for what I am looking for.

look good mate, but remember the soundcard is going to be placed right under the top gpu, therefore it will block one of the gpu fans.

and I'd get a pci -e wifi card, the card would then be placed above the top card, and again not impede any airflow.

Infact You could chin the wireless of completely and get a good set of homeplugs, then get a PCI -E soundcard instead, so both ya gpu's have nothing blocking the airflow only a soundcard above.

Hope that makes sense (long day)
