I have a motherboard that Supports Quad SLI and Quad Crossfire
I want a Graphics Card that had Two GPUs in it.
So I cant have another Card to make a full set of Quad SLI or Crossfire.
NVidia 690, AMD 7990 or 295x are about the only ones that are semi modern, with the 295x being the current gen cards. Pretty short list.
IS Gtx 960 or 760 and AMD r9 290x or 280x are Dual GPU Cards>?
Obviously they aren't, some of them might be dual-slot but that relates to size of cooling not chip configuration
Dual-gpu means 2 gpu chips are on the same PCB in which case this is a list (as stated in previous post):
This is an odd request? What are you going to use this for? Quad sli or crossfire is very inefficient and in some cases I have seen benchmarks where it performs worse than 2 or 3 way cards. For modern GPU's you need to look at X99 motherboards for the extra pci lanes. Unless you really know what your doing you could waste a lot of money on a setup that you dont use or is slower than a setup which is much cheaper
I don't think he actually realizes putting dual-gpu x2 sounds maybe posh but in fact you need really top components PC that is about to support it. Yeah maybe mobo supports it but you need like 1,5KW PSU, CPU that actually handles such GPU horsepower, ultimate cooling and more:
So can I use these(The Ones I have Listed) in Quad Sli Supported mobo?
(If I add two Identical Cards?e.g.2x gtx 960
4 x 960's is an awful idea from both a power and VRAM point of view
You would be far better off with dual 970's or 980's. You still have not said what you plan to do with this setup. Quad Sli does not give you 4x's the performance and you get the same amount of VRAM as a single card.
