I have a single GTX 480 and have wanted to go SLI for quite some time, but moreso with BF3 and Skyrim (I want Ultra mode!). Could I get some opinions? First of all, can you SLI a 570 or 580 with a 480? I can't find what the final verdict was from NVidia on that. Secondly, if you can, should I go for the similar performance of the 570 with less RAM, or go with the same amount of RAM and get the 580? I will also be upgrading my PSU of course
Well I just answered one of my questions: NVidia's SLI FAQ says that you can't pair two cards with different amounts of RAM, so I'd have to go with the GTX 580. So I guess what I need to know is if it's worth doing that, or just dumping the 480 altogether and going with dual 570s?
If I have to do that, perhaps it's worth it to wait for the next-generation architecture, or even the one coming in 2013 and just build a completely new PC!
Yep, that's what I'm thinking. If I can find another 480 it might be worth it, but then I'd need to beef up the PSU too, so forward thinking here is key. If a single 480 is good in Skyrim, I think I'll wait for the 6 or even 7 series and go completely insane on my next rig.
Wrong the 570 is on percentage 1% faster and sometimes slower in a lot of cases.
I remember i read somewhere, i guess on "techspot" that it was a faster than GTX 480 by 5-10% and faster than GTX 470 by 22-25%.
Didn't check a lot of reviews on the GTX 570 vs 480, so i took the info from the source and believed it.
My apology then for the miss-leading.
So I got Skyrim and so far a single GTX 480 at 1080p Ultra settings with 4xAA 16xAF 4xTSAA, I'm pretty sure I sit around 30fps and dip down to 15fps every so often. I think just for the extra oomph factor I'd still like to SLI to keep it at 60fps.
To add to this, Tom's did an article on Skyrim performance, as most of you have probably read, and the GTX 570 was pulling less than 60fps at the same settings described above. With VSync enabled (forced in the game), that should drop to about 30fps, correct? Not sure what Triple Buffering would do here, but it's worth FRAPSing I think.
