I currently have a evga gtx580 1.5gb, and have a chance to buy an extra card with the only difference being its 3gb. My questions are A) If running a 580 1.5gb with a 3gb in SLI is not as effective as 1.5gb SLI or 3gb SLI, how much slower are the mixed cards in SLI going to be compared to the matched cards in SLI? .. And B) would it be smarter to just buy a single gtx 780 and get rid of the 580.
I looked everywhere but couldn't find an answer, Ideally I would like to see a fps comparison between the mixed SLI (1.5gb with a 3gb) and the matched SLI's (either 1.5gb SLI or 3gb SLI). But any opinion would be appreciated. I don't know much about SLI's but ive heard they can cause other problems compared to running single cards?
....So basically HOW MUCH SLOWER is running a mixed vram 580 sli compared to same size vram SLI?
thank you for any answers.
(first time question, sorry if its a bit confusing)
ALSO
If anyone has actually run a 1.5 and a 3gb together please let me know what happened, speed and compatibility wise.
