APU to GPU Crossfire?

[Clovis]

If i had an AMD A8-5600k and a r9 280 would i be able to combine them together? Im pretty sure that the amd a8 is an APU not a CPU so could i take the 2gb of graphics that the APU offers and combine it with the 3 gb that the r9 280 gives? If not then i have a second question. For the price (102$ for xfx r9 280 and 230 for gtx960) and performence, what card would be better? the gtx 960 or the r9 280?

No, the two are not compatible for Crossfire. R7/R9 cards are not cross-compatible with other cards in Crossfire, not to mention that both GPUs have different processor archetectures.

Also, video memory in Crossfire/SLI is not additive, you total amount of memory would be equal to the lesser amount of VRAM that either GPU has access to since the data needs to be mirrored across both GPUs. In the case of one having 2GB and one having 3GB, you'd still be left with 2GB of total available video memory.

r9 280 is alot better than the apus gpu could ever be
and too much for its cpu to handle
the cpu will be the bottleneck for games with settings high enough to max the r9 280

so the A8-5600k is too weak for the r9 280? What would be a more suitable card for the a8 then?

amd apus are a good match for their cpu/gpu combo

save up for an i3/i5/i7 and board combo then add an r9 280/380+ or gtx 960+

Well i just decited to get a really good APU i have another thread about it now. Unless of corse i could get more performence for about the same price by getting a cpu gpu separate but otherwise id perfer to just get a high end APU

sorry, but there are no 'high end' apus
the are all low htpc grade gpus for modern games

[Clovis]

so even the A10-7870K with Radeon™ R7 Series is low-ish end?

[_I_]

yes

[Clovis]

how much could the a10 7870k do then? could it atleast run ark survival evloved on low? My old A8 couldnt even on the lowest graphics. it was unplayable. So was Far Cry4 on the lowest settings.

[_I_]

it will run, but not good enough to be playable

thats the a10 with r7 250 which is stronger than the apus gpu
