AMD-Raedon Graphics Upgrade with Crossfire support considerations. Any ideas ?

Sparxz · Mar 10, 2014

I have a ASUS F2A 55-M LKS motherboard with On-Board AMD RADEON HD 7000 series.

I have been looking at The AMD CrossfireX Chart and trying to figure out, how I can do an upgrade without ending up with a Card that costs more, but not an improvement on the existing/built in APU AMD Raedon HD 7000 series, as I have read that can happen.

I have been looking at cards reviewed here for less than £90 like:
Best PCI Express (PCIe) Card For ~£90: Radeon HD 7770/Radeon R7 260X

Bus BUS is PCI Express x16(3.0?) acording to the MB manual.

Any ideas? Thanks.

what is the exact APU graphics? also are you wanting to dual monitor with the APU graphics along with a dedicated GPU or just want a better dedicated graphics chip all around?

The best current APU with integrated graphics is A10-7850k. It is almost on par with HD 7750 DDR3 version.
7770 will definitely be faster that that. 260x is even faster (this depends on the manufacturer and the model though)
R7 250 is ~ on par with the A10 (less SPUs but faster memory) but faster than anything else (but not by much).
If you are AMD fan I'd recommend getting the 260x for a significant performance boost.

xbizzaroz :

I could see the APU graphics code when I was in Win7 yesterday(I duel boot with OpenSuse) and comparing to this chart:

But I was suprised to see it was not listed. I am doing maintenance reparis on the Win 7 partition now.
Hope to add second monitor in next few months.

Interesting info in comparisons. You must have tried out a good few Graphic cards etc.

By going with the options it looks like, I would not be using Crossfire at all, but replacing/by-passing
the APC buit-in graphics. I was hoping to utilise existing also.
Thanks

There is info all over the net

you just need some time for searching and reading, but the forum is here to save your time.
BTW there are also a lot of complains in the net for the xfire behavior in asymmetric config (APU + faster GPU), so you can try it but be prepared to disable the integrated video at all and use only the new card. xfire works best with dual identical cards (like dual 260x-s)
Not sure if you can use the integrated video to a power secondary monitor.
I personally prefer "full power" CPU and "full power" GPU, separated. The APUs, are good for integration, less system complexity, for low power consumption, but for performance - this is not the way.

There are enough problems with crossfire and like GPUs. The only AMD GPUs that offer a hardware-level solution to the dropped/runt frame issues AMD cards are notorious for is the R9 290 and R9 290X. I wouldn't crossfire any other AMD cards.

I would not even consider crossfiring an APU video solution with a discrete card. That's just a headache waiting to happen.

Glad to be closer to a decision, but disapointed with crossfire, that would leave me "Cross" & putting my PC on "Fire" in anger ! [Maybe thats what it really means?!]

I though AMD and ATI were further along in flexable solutions? Pity not to be able to use the onboard processing.
Looks like I will have to spend more than I expected to 'punch' above the current weight.

Thanks guys for all the input.
