Gtx 580 3gb and 1.5gv Compatiability

post #1 of 4
Thread Starter 
Okay just a quick question here for when I go tri sli.
I really wanna go with the 3gb version of the 580 when the new nvidia gen comes out when I can get it at about 100-200 less. I was just curious I currently run 2 gtx 580's in sli and there 1.5 gb versions I was wondering if i bought the 3gb card would it be compatable and would I just have 1.5 gb available of vram. If you guys understand what i'm trying to say here.

You would be limited to 1.5GB.

Yup, same texture data needs to be applied to each card in SLI. 3GB of data cannot fit into 1.5GB framebuffer so cards will only use 1.5GB.

yes it will work and yes it will only run @ 1.5GB... so basically a complete waste of a 3GB card
