580 SLI or 590 SLI?

post #1 of 9
Thread Starter 
My question is, which would be better?
3 GTX 580's (1.5GB) in SLI? Or 2 GTX 590's? Or 3 GTX 580's (3GB) in SLI?

If money isn't a restriction I'd go 3x580 3gb personally

3 x 3 gb 580's in SLI is for sure the best choice, of the given three choices.

Depends what you intend on doing. Personally, a single GTX 580 3GB is more than enough to run most games maxed out on a single display. If you're looking to do multi display and/or 3D vision then the multi GPU setups will be a lot more beneficial.

Depends on what you want to do. If you are doing a single monitor then either. If you are doing three monitors like what is in your sig then the best option would be 3 x GTX580's 3Gb in SLI for the added memory bandwidth. 2 GTX590's still only give you 1.5gb per GPU and there is little gain from Tri-SLI to Quad SLI, plus GTX580's overclock better. Cost would probably be about the same, so I would do three GTX580 3Gb models and call it the day.

I would go for 580's (3gb) in SLI or (to save on some cash but same performance) 1 580 (3gb) and 1 580 (1.5gb) in SLI and make your 3gb version the main one. Reason is, because when in SLI the second cards ram is not used. Also get a SB-E 3930k.

2 x 590's (not worth the money, if used in surround resolutions they choke due to the restricted buffer of 1.5GB)
3 x 580's 1.5GB (Is faster than 2x 590's) 3x 580's 3GB (is the same in performance as 1.5GB versions except when you get upto resolutions that demand the extra buffer, 3GB has no benefits in peformance until ultra high resolutions like nvidia surround for example).
