Can I plug my old HD4850 and a new HD6450 together on at the same MB?

[Murjovic03]

Hello Mates,

I currently have a Radeon HD 4850 card and I’m very happy whit it.
But I bout a new 3D TV and now I need a new card with HDMI 1.4 port.
I currently can’t afford to buy a new card for let’s say 150+$ (for 6850 for example) and I’m still happy with my old HD 4850.
On the other side there is HD 6450 which is very cheap for about 50$

Can I plug my old HD 4850 and a new HD 6450 on at the same time on the other PCI-E slot of the mother board?

The general idea to use the old HD 4850 for games and the new HD 6450 only for the HDMI 1.4 port.
My mother board is Gygabyte with 780G chipset.

Has anyone tried this such loony idea ?

Best Regards,

no you are not able to do this.

if you can fit both cards on there you can run it for multi monitor applications but you wont be able to crossfire it

The best thing to do is to sell the 4850 card used and buy a 6770.

The 6770 is a extra $50 vs the 6450.

If you sell the 4850 cheap to someone for something like $40, it ends up about the same cost in the end.

it will work but you'd have to manually change card display through windows to switch each time.

Thanks All,

I decided to go for this one SAPPHIRE HD 6670 1GB GDDR5

It looks like it has the same GFLOPS like my old 4850 card but on the same time it features UVD3 which is a big plus to me.

Now another question my MB conforms to PCI Express 2.0 but the cards specs says that HD 6670 is PCIe 2.1 !!!

Will this work on my current mother 780G board Gygabyte GA-MA780G-UD3H ?

Thanks and regards

yes it will work

PCI-E 2.1 and 2.0 are backwards compatible with each other, no need to worry. Good choice with the 6670, it is currently the best lower prices graphics card out there and one of the best that can run without a beefy power supply.
