ASUS, not to be outdone, has one-upped Gigabyte. Check out the N7800GT DUAL, if you haven't already. It has it's own power brick. Does this worry anyone else? ;)

That review is much better than the one I saw before. I really like the design of the heatsink. Its interesting that they decided to add that external power supply, I wonder if we will see ore of that. Too expensive for me to even consider buying, though.

that external power cord is a good idea i think.........takes some load off of your PSU, more juice to your CPU

I want one........[/quote] what for? its not as good as SLI. it has the only advantage as space. not having two cards. thats really the only good thing it does. the two GPU's have to share a bus board, AND an external bus leading to mobo, if things arent already cramped in these new cards enough. on top of that, they have to share memory. SLI would perform better. this = waste of time, money. if they focused on makeing a better GPU, rather than piling the existing ones on top of one another, we would see better cards for cheaper, faster. *r580* [quote=S.T.A.L.K.E.R.]that external power cord is a good idea i think.........takes some load off of your PSU, more juice to your CPU

i could see this idea, but a good PSU has plenty of power to go around. definatly cheaper and easier too. again, i would call the external power supp a disadvantage. thats a imho though.

Correct me if I'm wrong (and I really don't know what I'm talking about), but in SLI motherboards, doesn't each slot essentially act as a PCIe x8 slot? I thought that the bandwith was the same and it had to be shared between the two cards in SLI. And, where did you get the idea that its not as good as SLI? It scored higher in 3Dmark05.

maybe not in performance, but maybe bandwidth wise. this is some stuff i read in a earlier review. both pci-e slots do run at 8x. this is beside the fact, and means nothing. since current technology does not require a 16x bandwidth, x8 sufices perfectly, even for AGP cards of the same type. like the 6600 GT agp benching higher than the pci-e version. the point is the external bus on the board having to be shared, along with the memory. good thoughts, and points though.

1) SLI proper does seem to hold a bit of a performance advantage over this monstrosity. 2) It doesn't share memory: each core has it's own unshared array of 256MB. 3) Older nF4 chipsets split the PCIe x16 lane into two PCIe x8 lanes; that's essentially what this does. The latest revision doesn't have this limitation.

Suspicion: the use of a common slot does still negatively impact performance, particularly given the 1.2GHz memory clock on this thing. I think it also suffers from the same "slay the SLI bridge" problem that the 3D1 had (namely that you can't populate the other slot with anything other than a PCIe x1 card. Don't know this for a fact yet, however.

More of a proof-of-concept than anything really, but it is a FAR more elegant method of using eight monitors than Gigabyte's whatthehellever QUAD motherboard. Although now that I think about it, some idiot will probably haul off and mount four of these DUALs on one, just to have support for what, 18 monitors?
