I only use one GPU so I could not answer that

But with a multi core CPU

I can run anything I want without it lagging out SL.. If running SL and I need to log in more than one viewer to do some work. I experience no lag or slow downs.

Multiple CPU cores has it's advantages thats for sure And a noticable increase of FPS

My Viewer never crashes anymore lol

 There used to be an advanced debug setting for the older viewer to use Multiple threads. I think that is on By Default now in viewer 3. But you can still find that setting in older viewers

 Before, I would have to close SL just to run Photoshop. Now I can run 2 viewers. photoshop, blender, web server, sl group joining bot, and much more at the same time without any lag lol

 I only use One GPU tho . I am sure 2 would help but not sure how well SL utilizes SLI/Crossfire technology

It wqould probably be benneficial if used in a sceenario like mine. Using SL at photo shop and other rendering programs ad the same time.


RunMultipleThreads is actually off by default in viewers now not on. I don't notice any difference with my 4 cores off or on in a brief test so I don't know how useful that setting is now. I may do a more extensive test some time. There were a few threads on this issue from Autumn 2010 on when LL took the option out of the Advanced Menu in v2.2.0.

To see the effect of multiple cores I think you have to enable it and then restart the viewer. To me I beleive it's a help but that could be due to my specific cpu. Not all cpus are using hyperthreading so maybe that explains some people benefitting and others not. Enable VBO for Nvidia cards is a definite benefit maybe up to 30-40%. Window size especially when in Shadow mode. For me installing the viewer and Sl cache in a RamDisk is a benefit.

 

SLI has not been of any benefit for me. 2 GTX 460's and the fps will plummet 20-30) fromm200+ fps with one card. I have tried everything suggested on the web and it acually seems to work it's just that the benefit is VERY POOR.

 

The GTX 670 recently came out for $400. Benchmarks indicate maybe up to par with a GTX 680 (about $500-530) and about 30% better than a GTX 580 (which is still expensive). Now a GTX 580 is about 50% better performance than my GTX 460 in SL as I compared with another avatar especially in shadow mode which is where faster cards will profit. Of course this is not necassary for most people but I produce Machinima so I nned maximum performance to broaden my film ideas.

I have a highly overclocked watercooled quad core Intel i5 750 (derived from the i7 not the normal i5) which was a very good gaming chip when released, but it does not use hyperthreading so going on what you say, that would explain why I don't see much if any difference.

It's old news that Nvidia is better in OpenGL than ATI. In fact Nvidia's new drivers have crippled the 400 and 500 series so much in OpenGL that the much older 8000 and 200 series outperforms them consistently. The 400 and 500 series OpenGL performance level are more like the old 6000 series now. This is done on purpose so Nvidia can sell more professional line cards, which have basically the same hardware but drivers that are "optimized" for OpenGL, ie, not-crippling.

How can you tell the OpenGl performance is crippled and is their a hack to use different Drivers possibly the ones used by the Quadro drivers?

There are OpenGL benchmark software out there that are free to download. Just google. No you cannot use the Quadro drivers for consumer grade cards. Yes there are supposedly driver hacks but I haven't found any that works. Also whatever you do, don't get the new Nvidia 600 series. They are better than AMD/ATI cards in DirectX games, finally, but are capped in OpenGL performance even more so than the 400s and 500s. Even the 400s is better for OpenGL than the 600s, and 400s have been known to have OpenGL performance issues. I might have to go with ATI from now on just for SL, even though ATI cards suck at tasks like video conversion compared to Nvidia cards.

I did  test with my i7 930 chip. With hyperthreading enabled I get the same fps as when I idsable it. However the cpu usuage goes up to 50% from 20% so if I was running another program like FRAPS etc I'm gonna have some issues possibly as it maxes out. I have heard it said i5 is great fro games I guess the one shortfall would be multitasking although these chips are so fast these days even that's not a HUGE issue. I know I can have Firefox and 2 viewers running with no issue as far as the PC goes. GPU is a different matter as I have to reduce viewer settings considerable for 2 viewers to run without lag. I have a GTX 460 so an upgrade may be a huge benefit in that regard.

At Linden Lab Realms I get 250 fps in HIGH with no AA or AF and in shadow mode close 100 fps at 1080P. With a GTX 460 768 mb EVGA and a i7 930. I know someone gets about 50% more in shadow mode with a GTX 580. Then I know a guy with a 580 getting maximum 20-40 fps and down to 6 fps with shadows enabled. Plays DX11 games no problem but SL sucks. We checked his gpu usage in gpu-z and it was a lot lower than mine. Could be different brands even though the same gpu are optimised differently? I have used Furmark to benchmark OpenGl however not sure what is good or bad and I heard the isses can be LL's version of OpenGl comapred to Nvidia? I was going to upgrade to at least a 570 or 580 but when the 670 came out was going to go that route. In theory double the performance of my card however I only play SL so waiting to see if anyone has seen better performance.

Don't upgrade, especially not to the 600 series. What are you getting from FurMark?
