Default Re: debating a second gtx 590 or two gtx 580 3gb's

OK Wheeljack, here's why I posted about the AMD scaling (to date):

http://www.guru3d.com/article/geforc...i-sli-review/5

Notice how Guru3d gets almost perfect scaling going from single to SLi at 25X16 8X16X using an i7 at 3.7GHz?
53fps to 100fps

I just ran that bench with my 2GB GTX560Tis at 25X16 4X16X, all maxed, on a Phenom II at 3.4GHz and went from 58fps to 84fps.

That's only 44% scaling. I can try it at 8X, but I don't think my scaling is going to more than double adding 4XAA.

That is why I said you should buy a cpu, not GPUs. Whatever GPU you put will be a good deal slower on the 1100.

As far as waiting/gambling on Bulldozer, yes, I might as well having just spent the money on the motherboard. I was only answering the question based on what currently exists, not what will someday and may or may not be good.

Hope this helps.

EDIT:
Used 8XAA like Guru3d, 49fps to 78fps, 59% scaling for AMD, 88% on Intel.
