Using 2 different GPU on my computer, PLEASE HELP!!

post #1 of 48
Thread Starter 
Hello, I am currently using Radeon HD 5450, but would also like to add Nvidia GT440. Can I actually do this and how does the CPu know
which card to use or how to divide the tasks?? Opinions would be appreciated , THANK YOU! thumb.gif

Yeah you can do this, but why? Do you need more monitors or something?

You can, but they will work independently, what are you planning to do? Examples would be great
post #4 of 48
you cant combine them though. one is an nvidia card and the other an ati. there is no crossfire/sli to be done. you would need two 5450s or two gt440

I just bought a new Shimian 27 inch monitor. It is 2560x 1440 res. The computer now runs choppy when I play my 3d game.
Adding another card would help right? I realize I could replace the Gpu but I could get nothing for old one, so I figure just add another budget GPU
the GT 440 is $80 online.

No, it won't help, you need 2 similar cards.

if by adding another to help, you mean taking advantage of both gpu's simultaniously on one program? if so with those cards its not possible. you would need 2 identical cards in crossfire or sli

Basically I was hoping to use my old card for the Monitor and the new card to run the 3D game.
Does the Cpu automatically just use both somehow? I'm not exactly computer savvy and just trying to understand how this would work?

if you want both graphics cards power to run 1 game (regardless of which card the monitor is plugged into) you need both to be the same. This is a technology that ATI (AMD) and nvidia offer for 2, 3 or for identical cards

Ok guys thanks for you input. One more question. Would I get better performance if I add another HD 5450 or just Have one GT 440?

I know there are better cards out there but I'm sort of on a budget. thanks again
