Hello!

Would anyone know if adding this old GPU into my current PC would be compatible, and if yes, would it have any real effect? Feeling uninformed:

Old Gpu: eVGA e-GeForce 6800, 128MB DDR

Current setup:
Windows Vista Home Premium (x64) Service Pack 2
3.40 gigahertz Intel Core i5-3570K
8154 Megabytes Usable Installed Memory
Board: Gigabyte Technology Co., Ltd. Z77X-D3H
Bus Clock: 100 megahertz
NVIDIA GeForce GTX 460 SE

Nevermind, resolved the question. I'm silly.

If anyone is curious, I believe my motherboard and GTX combo limits me to 2nd GPUs that interface through PCIEX16

You are wasting cpu power the 3570K is too high of a quality processor to pair it with a 460. Get at least a 660 or a HD7870 please, this pains me.

Your motherboard has two pcie 3.0 and at dual mode 8x 8x, no bottlenecks for dual gpu setups, but i don't recommend adding another 460 gtx, get a better card from current generation of nvidia cards, a decent upgrade will be the 660 gtx/660 ti/670 gtx.
Keep in mind if you want to add another one later for those mentioned, you need a psu with 600-750w depending on which card.

While you could add the card the only thing it would do is increase the amount of monitors you could have in extended desktop. Its not going to increase performance as you can't sli the cards and the 6800 is too old to run physx.

Cool! Just to see if I understand correctly, if I were to buy a 660 gtx, could I run it at dual mode with my current 460 gtx? This intrigues me greatly

No, only with another 660 gtx, but you can put the 460 gtx as a physx card.

Exciting! Would I enable that through the nvidia manager software or do I have to install things in a special way? Thank you for all this info

Just plug the 460 gtx in the other pcie 16x/8x slot, and then enable physx in control panel with that card.
