Derparch :
I have a buddy who has a 780 ti He'd sell to me for 300. But my dual core a10 won't work with it. Any ideas?
Sorry dude, but as of now, all the AMD APUs will definitely bottleneck your GPU, except FX 8350 (Its not an APU but a Pure 8 Core Processor which comes under AMD's FX series and all the APUs come under A series) that too when overclocked @ 4.5 GHz.
Also, why would you get such an old card for that Price, you can get an R9 390 for that price which does very well for its price also, I would have suggested "NVidia’s GTX 970" but didn't because, NVidia’s GTX 970 has an issue where the GPU can't address its total 4-GB of VRAM without reducing it's bandwidth from 224-GB/s to 196-GB/s which in turn might give you a big performance drop.
So, why did I even say you this about NVidia’s GTX 970? Well, for you to be careful.
Hope this helps you, fell free to ask any questions...
