APU VS ((CPU + GPU)) which is better
- Thread starter puzzle123

To be slightly more...opinionated 
:
If you're looking for sheer performance
An APU will be better than a CPU/GPU combo only if you're specifically taking sub-100$ components for the CPU and the GPU. Otherwise, the combo is going to beat the APU, period.
If you're looking for rock-bottom prices
Pretty much nothing beats an APU.

XFire/SLI can happen (as of now) only with identical chipsets and vendors.
For example:
- Two AMD R9 280x can Crossfire (similarly, Two GTX 770 can SLI);
- An AMD R9 280x and an AMD R9 270x can't crossfire (similarly, a GTX 770 and a GTX 760 can't SLI);
- An AMD Radeon HD 7970 can, however, Crossfire with a 7950, albeit the performance of the 7970 will be leveled down to meet the 7950's speeds.
- An AMD card and an Nvidia card can't Crossfire/SLI, albeit some hybrid configurations were tested on Physx intensive titles by letting the Nvidia card simply handle the proprietary libraries. All strictly unofficial of course.
Supposedly, DX12 is going to break that 4th point by letting GPUs interact with each other regardless of chipset, vendor or speed. It'll all be leveled down to the slowest/smallest common for all the GPUs in the system, but it's supposed to work. Haven't been up to date with its info lately, but that's the last thing I've read at least (I believe it was some article over Guru3D. Interview with MS about the upcoming libraries or something like that... for all I know, it could've been an April's fool, lol)
