I know that you can't have two GPUs in a machine, but I was wondering this... I want to buy another Harddrive for my computer. It takes SATA drives. I currently have a GeForce 8800GT. My old computer has no hard drive but has a Radeon X850. The X850 has a capture card built onto it that I want to use, but I am buying a SATA Drive for my current comp and would rather not buy an extra EIDE drive, because my old comp takes them. So I was wondering, can I have both GPUs in my comp, and have one for each hard drive? So, have my 8800GT drivers installed for my main drive with Vista, and then have my X850 installed to my other HD with XP, and have them in the same computer? Would I be able to do this or would the cards conflict?

You can. It is called (Tri-)SLI / CrossFire(X).

Anyway, what you are saying probably won't be possible because your motherboard will detect a second video card with no vga/dvi connection and throw a fit (beep at you :P). PROBABLY. I am not sure of this. Driver wise, there would be no problem. The problem would be that you would need a controller to select which graphics card is used before booting. If, for some reason, you are able to boot, you still need to have two monitors (one for each card), or you have to change which card the monitor is connected to each time you want to boot into a different OS.

Seems like it would be a complex process, if there is even such a controller that was made for that purpose. I don't really think it's worth the effort.

Oh, I wanted to note that there is a exception to this. With Nvidia, you can use a secondary card that is not in SLI to process physics. I am unsure if you can use this feature in another way; however, it certainly shows that having two different video cards in a system is possible on a hardware level. Thus, it will depend on software limitations.

You could swap the cards depending on which OS you're going to be booting in to.

Awkard and clumsy, but otherwise its still difficult.

haha I meant you can't have an Nvidia and an ATi in at once. But I was planning on switching Harddrives in and out and leaving both GPUs in. But having my Windows Vista HD (my main) linked to my GeForce, and having the XP one linked to my ATi. So basically I can't have two in at one time, because it will see that there are two and it will flake out? So if I have the Nvidia drivers on my main HD and have nothing to do with the ATi in it, it will not like it? EIDE drives are hard to find for me. Can you install Windows on a external HD and use it as a main HD? Sorry about the noob question, I am not too familiar with external HDD's lol :)

I think it would be much easier just to get a seperate TV tuner/capture card. I don't think what your describing would work.

Why would you want to? It would be nowhere near as fast and a internal SATA drive. Maybe if your using a external SATA drive, but a regular USB drive? No way.
