Need advice on Radeon R7 xxx

[rob65803]

I have a AMD A10-7850K APU on an Asus A88 Pro Motherboard and running Win7 Home Premium. I am thinking about adding a Radeon R7 xxx either as crossfire or dual-graphics or whatever they call it.

Has anyone actually physically seen this work together? As opposed to it should work in theory.

Any thoughts would be greatly appreciated.

I also read this someplace, I wish I could give credit but I just copied and saved.

Q - How do I crossfire an R7265 video card in an AMD A10-7850K APU on an Asus A88 Pro Motherboard?

A - You can go into the BIOS, make the 6670 the primary GPU and then go to the AMD Control Panel and somewhere there should be CrossFireX options. In there, activate CrossFireX and your performance should be doubled!

My expertise about all this is non-existent, but would it be this simple?

R7 250 for pairing with the 7850K, or R7 265 or R9 270 (non-X) for standalone.

You want cross fire on that computer? Like why? Its obvious that the cpu will bottleneck anything better than an 280x and even that may get bottlenecked at lower resolutions.

Plus that mobo only has 1 pci-e 16x slot.

I'd get up to a 280x on your computer depending on how much money you got obviously.

I had read various places that you could not go above the R7 250 but that is about the only information I could find, and very little about cause and effects.

Yes, for dual graphics you're limited to a fairly slow video card.

Ignore dual graphics (it never works as well as it should) and grab an R7 265 or such; you're better off with one powerful video card.

I wouldn't bother with an crossfire with a APU. The 7850 performance is somewhere bwtn a R7 240-250. Even if it could work, you'll probably get high jitter.
And the 7850 will bottleneck a 270 or 260x, so set your sights low unless you're planning to upgrade the cpu/mb.

Um... No? Maybe in some games, but not many. Bottlenecking a 260X just seems like a silly thing to say overall...

Frame pacing works fine with Kaveri. I wish people would research before giving false advice.

...........And, as I learned after doing some more probing, the 13.35 driver is actually a much more important release than it at first seemed. Not only is Kaveri-based Dual Graphics frame pacing enabled, but Richland and Trinity are included as well.

There are lots of reviews. Google "Kaveri dual graphics"

Frame pacing works fine with Kaveri.

Multi-GPU with anything other than a pair of high-end GPUs is a terrible idea. What is the OP going to do when they want to run Company of Heroes 2 or Battlefield: Hardline? Just sit there with the lousy performance of his iGPU?

You could run dual graphics with the MSI R7 250 OC card, I think it’s selling for around $80 at NewEgg. Here’s a link for a review that Overclockers did.

I really appreciated (and enjoyed) each and every post. I have never had such a knowledgeably and sincere group reply to a query.

Before I posted the question I knew nothing about video cards. But I could not understand how I could research anything as much as I have in the last 3 months and in reality I knew less about what I should do than I did before I started.

Now, after you all were kind enough to share your thoughts, I better understand how I could read one thing and be more confused than I was before. I now understand that it must be truly an expanding technology and I was looking for black and white answers that didn’t really exist, yet...

I have concluded that I may have been a little pre-mature but that a R7 XXX should work for me. I’m not quite sure which one.

My most sincere thanks to all who took the time and trouble to try and help me.
