NVIDIA SLI Certification Program

It is good.

The article did not make clear to me that different revisions of the same card would work together or not, and will there be a loss of performance (or gain) by using the different revisions.

This is really important, because if you buy a GT 6800 now for $400, then 6 months from now add on another for $250 (but different batch, version, etc) - will it work and will it work as well if you had 2 of the same idenitical cards?

SLI is usless for an upgrade path unless we have some promises.

SLI upgrade path also will bring a new item to the table, how long will your video card maker be in business? Visiontek, ELSA, 3dfx have gone under...
 
I like the Idea of a certification program but I think that some changes have to be made.... first of all it does not certify that 2 diffrent brands of cards will work together. Second of all the tech reports has doubts of other chipsets such as via and ATI based motherboards will be able to be certified to use NVIDIA SLI
 
This was a well stated article as well as the replies that were made to the first post of this thread. They outline how rediculous i think this new SLI idea is.
The reason why i think this have to do with, those who do not buy a sli setup in one lump sum as i'm sure lots won't because of the huge cost of it. SO then, as was previously mentioned you might end up with problems down the line if your second card, is a) made by a different manufacturer albeit having the same chipset and ram config, b) is a different board revision. Not to mention that the motherboard will have different revisions as well. Not to mention that if the company you bought the first graphics card from goes under, then unless you chance upon finding the 2nd card for your SLI setup, you won't have a certified SLI setup, thus potentially creating problems for the end user. So many variables in this tech, i'm surprised they're pushing it and promoting it with out ironing out these obvious crinkles in it first. Sure a single card solution dosn't perform as well, but i'd much rather give up 20%-45% performance increase if it means i have a better peace of mind and less headache on getting my computer to work well. Not to mention the cost of a single card upgrade is much cheaper.
