3 285's = 3GB memory, 720 streamprocs, 648 / 2484
2 295's = 3.5GB mem, 960 streamprocs, 576 / 1998
(I'm not really trying to argue, here. I just started writing this stuff down on a random whim...then decided to make a post out of it. :biggrin:
These clocks and such were taken from the standard EVGA cards.)
At first glance, the 295's advantages over the 285's are obvious, and they cripple the previous things I said. All I really want to point out, though, is the rather large difference in clock speeds. I don't really believe that the extra RAM or a few extra streamprocs (aren't some disabled on the 295, anyway?) really do make all that much of a difference.
Is there even any game or normal home application out there that could use a full 3 GB of ram on it's own? Never personally met one, and I'm not saying it's not out there.
Again, just trying to make a point of the higher clocks, and better OC ability you can get out of the 285's.
You can't disable SLI on a 295, right? I like the fact that with 285's I can turn that on and off as needed if I were running some older program that decided it didn't like more than one card at a time. 285's are also likely to have a better resale value, if what I've seen happen to previous dual-gpu cards is accurate.
No matter what we as consumers do, there will always be something fast just around the corner. If you worry about that you would be paralyzed with indecision as there will always be that next better thing coming out!
