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
 
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.

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

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
