 So this is my usual thing where I compare the lengths and physical characteristics of a bunch of graphics cards so our Featured du jour today is the GTX 590 from Nvidia this is a dual GF 110 card It is so it's SLI on a card We've seen dual GPU cards quite a few times in the past now now these are fully featured GF 110s These are exactly the same GPUs that you find on a GTX 580 so one of these so you might ask Well, how did Nvidia manage to put two of those on one card and the answer is that they are actually down clocked Well first of all they're binned very carefully for the best possible Graphics cards are the chips to put on it and then second they are actually down clocked So they do have less performance than a single GTX 580 But they more than make up for it by having two of them okay So this video card has an 80 millimeter fan in the middle it has heat sinks on either side For each of the GPUs it has three DVI outputs with one mini display port So those three DVI outputs this is another unique thing about this card allow it to support 3d vision surround or just plain surround off a single card that is 3D displays over DVI So that's pretty cool. It does support quad SLI because it has one SLI finger and It needs two PCIe 8 pin power connectors, so let's just Contrast it against these other cards in terms of length it is an 11 inch card, so I'll just show you guys that There you go, it's an 11 inch card So you compare that to the Radeon HD 6990 which is a one foot that is a 12 inch card and to the GTX 580 which is only a 10 and a half inch card now the 69 Whoops I'm gonna wreck my tablecloth here the 6970 is almost 11 inches And then if we go all the way down into kind of the mainstream cards then we end up with a GTX 560 Ti and that is a 9 inch card so just for contrast you can look at what it would take to fit a GTX 590 in your case versus a GTX 560 Ti sort of mainstream single GPU card now there are other Considerations to bear in mind as well this fan needs to have a fair amount of clearance around it because with two Fermi's in there. There's a fair bit of heat being generated, so you need to make sure it has adequate ventilation and Yeah, that's pretty much where I was going with that you got to make sure it has adequate ventilation you also need to make sure your case has overall adequate airflow in it because half of the heat is going to be exhausted directly into your case out this side and then a Fairly substantial amount of it is going to come out into your case this way and then the rest will be exhausted so this is going to kick a fair amount of heat into your case and You got to make sure you have lots of fans to keep things cool.
