What about RAMs ?
RAM's aren't important for SLI/Crossfire.Just make sure you buy something that's compatible with your CPU and Motherboard.



So can I run a gtx 660 ti 4GB ram in sli with a gtx 660 ti 2GB ram and make the 4GB ram dominant. That is what I'm getting out of that statement ?

so then I should just buy two of the 2gb cards if I cant utilize all 4gb? I am planing on buying one now and then the other one in a few months. I am running a gtx 570 right now. From all the studding I have done on the subject the 660 ti SLI is right up there with 670 SLI, kills the single 680
and is fairly! close to a gtx 690 . but I can buy the 660 for around $220.00 a peace so $440.00. a pare of 670's are about $600.00 to $700.00 one 680 is about $.550.00 the 690 is around $1000.000. so I think Lb for Lb $ for $ this is the way to go ?. I have been reading up on this for weeks, I am not going off of just one benchmark but this benchmark really gives a good look at what my learning quest has lead me to belive. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=971&Itemid=72&limit=1&limitstart=6 ps. the only thing that gives me any doubt at this time is the 192bit instead of the 256bit. but I dont think that should be a factor in SLI?

Any thoughts Thank You for your time..

By RAM,I meant the computer's memory not the VGA's.


I personally prefer a single card solution over 2 or more cards but 2 660's don't cost much and will give you a great performance,so yes they're a good choice.Just remember that having 2 2GB cards won't give a total of 4GB graphic memory

The only way to get a single gpu to out perform a 660 ti in sli would be a gtx 690 at 1k or any other 1k card. a 690 is the only single card that will out perform a 660 in sli. I dont do amd cards. thanks again for your time.

I am getting ready to build my own, I have a GTX650 on my current PC, Can I use it as a deicated Physx card with a 7950 or does it have to Be Nvidia??? I know I can't xfire/sli. The 650 doesn't Sli, I hate to let it go to waste. Thanks.

This is actually not correct. The GTX 690 is not a single GPU, it's a dual GPU (basically 2 680's in SLI on one board). And also the TITAN is a real single GPU that has been shown to perform better than the 660 TI in SLI especially at higher resolutions where a larger frame buffer is required.

Thank You for the word correction I should have said single card not gpu. But I have done some testing with the TITAN and at the resolutions that we have tested on the 660ti in killing it. But I would agree with you having never tested in triple screen and such. but I picked my two new 660ti's for $440.00 for both cards. now it really is killing it..lol all I was trying to say was for those of us that can't afford 1k we can still get the performance of 1k. and now I'm benching 3way sli 660ti for a total of 598.00 I got a great steal off of ebay on the third one.yaaaa.. Thanks again for the correction!!

I currently have a EVGA GTX 560 Ti Superclocked. I want to add another and run in SLI. Is this recommended? I'm having trouble finding too many out there... Ebay being the only place that has them (around $100). But for the performance, the price is much less than comprable performance in a 6xx series card, correct?

No


You better get a 6xx card or wait for 7xx ones(if you aren't in a hurry)

Can Hybrid CrossFireX or Nvidia HybridPower be used with the latest graphics cards ? I'm not interested in using two graphics cards, but only to use the intelligent power management function, or, as they say, "unleashing graphics performance when needed, and switches to low-power operation for everyday computing " automatically.
Thanks

I'm doing a new build. Would you recommend a single GTX 780 or Dual 770s? There's a bit of a price difference, but if it's worth it I'm not opposed. I'm going to be doing a lot of streaming as well if that makes a difference.

no, streaming won't affect gpu performance (as to prefer one configuration over the other), but it will definitely affect cpu performance, so better cpu, better handling with multitasking...

a sli of 2 gtx 770s performs better than a single gpu, be it the gtx 780 or any other single gpu at the moment. so, if you go for a multigpu setup, make sure you get a 120hz monitor, cause you will mostly be playing at a framerate higher than 60fps..

I currently have a gtx 660. Should i just buy another 660 and sli it? It looks like you get near 680 performance..it will only cost me 190 dollars for the upgrade...it will hold me over until maxwell..whats your thoughts, guys?

well, that is up to you... if you feel like waiting for maxwell, buy one 660 now and save up for later.. you'd get near 680 hence 770.. that will be a boost in performance... i would do that.. though, personally i bought a 780 cause i had a gpu that wasn't directx 11 compatible and i couldnt play crysis 3 but that's another story...

Oh well im 100% sure the 660 is dx11. I play far cry 3 on dxll..at 30-40fps..the reason i want sli :p

Not only is it good but your 660 holds it back. You definitely want to go sli. Your cpu has plenty of power still to be unleashed!
