Question What would happen if i apply two different GPU in my motherboard?

[FoxInFlames]

Random question, really

I have a 3080Ti and a (very) old Radeon HD 6450, since the 6450 is a low profile card (and tiny), can i plug it into my second PCIe slot and use it for powering another monitor for icons and such? I don't think it would be very performance saving for the 3080Ti but the 6450 is just lying around and i might as well use it.

The 3080Ti is vertically mounted so the temperature wouldn't be hindered by another GPU horizontally mounted, i guess. I also have an 850W PSU so i don't think I'll have any power issues (the CPU is an i7 12700F by the way).

Depending on your MB, first and second PCIe x16 pot may be sharing PCIe lines so each one would use only x8 PCIe lanes and cut down on performance of 3080Ti.
What do you think you would gain by using such old GPU. even if it works ?

Do you have all video outputs on 3080Ti used already?
Just connect your second monitor to any free video output on 3080Ti.

I'm probably not gaining anything, i was just wondering if it would work, of course it won't affect the 3080Ti either ways but i was curious.

I'm doing just that, but i was curious as to what will happen if i used the other one as well

Yes it should work but probably at expense of 3080 performance.

It also happens that i have an old monitor that's under repair at the moment, with a dvi and RGB port and a great sRGB value which i want to use, since the 3080Ti doesnt have a DVI port, but the 6450 has them, therefore the question

Forgot to add, the other monitor will be mostly used for icons and images and discord, so the performance of the HD 6450 doesn't really matter

You can use HDMI to DVI cable/adapter for that.

I guess I'll do that if that's the only choice, i thought i could save a little bit of money by using an older GPU as well
