Hi before I ask my question I'd like to say I'm terribly inexperienced with computer hardware, so forgive me for my poor level of my questions.

Some of you might have saw me post something similar a month back.
Anyway what I need help with is, can I have three different graphics cards in SLI when I mean different I mean 2 Asus geforce gtx 690 cards and a PNY xlr8 geforce gtx 680 if they are not compatible what about 2 evga 690's and an evga 680 or the same brand of gpu's? Or will they be compatible if they aren't in SLI if not in SLI will they lose performance?
Or will it give better performance if I leave all three cards not in SLI then 2 690's or 3/4 680's in SLI. If that gives less performance or isn't even compatible at all the should I go with 2 690's or 3/4 680's,I'm more inclined to go with the 690's as they give better performance then 4 680's, cost roughly the same and puts out less power and heat consumption.But hey I'm not entirely sure.

Don't judge me I know it's overkill but I really wanted something this great even when I was young (I'm 17 so it's not that long ago) and still be great in years to come and money is not an issue.

One important fact is that a GTX 690 is essentially just two GTX 680s in one card. You can't SLI or CrossFire more than 4 cards, and since the 690s count as two cards, you can only SLI two of them at a time. I do believe you can SLI a 690 and two 680s (4 GPUs), but not two 690s and a 680 (that would be 5 GPUs).

A single 690 is very very close to the performance of two 680s, but remember that the overclocking potential is much less since the two GPUs together produce much more heat and consume much more power. And remember, you can have 4 680s or 2 690s, and no more. (or a 690 and two 680s)

This is a tomshardware review comparing the performance of a 690 to other cards, including two 680s in SLI.

You could also consider the Radoen 7970. They generally have more overclocking headroom than 680s and due to the latest drivers they perform very close to the 680.

To answer your question of if you can sli the 2 690's with a 680. Simply no. If you want to sli the cards have to be the same 690 with 690....680 with 680....so on and so fourth. I would suggest 4 680's since money is not an issue. 4 680's will perform slightly better than 2 690's. BTW 2 690's is the max for 690's since they are dual gpu cards. 4 Gpu's max. Also if you have 4 cards you wont be able to have any raid card or any other cards. If you must have other cards then dual 690's will let you do that


I thought 690 and two 680s would sli because they share the same GPU, no? Might lower the 680 clock to 690 clock...

GTX 570 and GTX 580 are not same GPUs. It's same architecture, but different GPU. GTX 570 has less cores. GTX 580 and 590 are the same so you can SLI them. You will be able to SLI GTX 690 with 680 as well, but only up to maximum of 4 GPUs.

Yes it may be the same gpu technichly but so was the 570/580 yet you could not sli them. I am sure the same thing would happen here. even if what would be the point in doing so?


In case he already had two 680s or something. Might not even be a possibility but sometimes it could be useful. I think you can crossfire the 5870 and 5850 and the 5970 interchangeably...

So what should I go with 2 690's or 4 680's I want the won with the best performance even if it's by a whisker

also can you clock the gtx 690 higher than it's original speed????????
