BF4 has been reliably played and tested, so don't write it off as 'broken and doesn't work' if that was true the press would have field day with EA multiple lawsuits by consumers over false advertisements / bad product. It does work, and is being played as we speak, the link I did provide (if you looked) uses the standard Metro Last Light test, as well as Tomb Raider and the APU WOULDN'T ALLOW THE GAME TO WORK UNLESS AT LOWEST GRAPHICS LEVEL. WHY?
No I am not failing to comprehend how your bypassing the GPU in the APU by adding a GPU seperately; YOUR failing to to comprehend disregarding that it (APU) as any impact what so ever as long as he has a 'mighty GPU'. If you bothered to look at the scores, which INCLUDE using a GPU to 'bypass' the APU (as you naively believe) did nothing more then give a extra 4FPS because the APU still bottlenecks any GPU when compared to say a i3, i5, AMD8xxx or heavens forbid a i7.
Basic 101: Data Code is stored (HDD) to be read (RAM) in chunks for processing (CPU) before handed to a component (Sound, Printer, NIC, GPU) to perform that code's instructions. So before you GET to a GPU you have these other players involved, the GPU does not handle the game ALL BY ITSELF. In 2013 games the coding for 'smart AI' and other things is NOT a GPU rendering task, it is a CPU TASK. Hence why all the AMD Fanboys with 6xxx are crying alot about how they can't get great BF4 play (for example) no matter if they put in a R9 or a 780 as compared to a i5/AMD 8xxx or better yet i7.
The APU is targetted to compete against a i3-Clarksdale / Sandy Bridge with Integrated Graphics performance level , I would never suggest someone use the old i3s for gaming because they were made for general (grandma emailing and looking at facebook pictures) computer use, not gaming. To suggest that the APUs would be any different is ignorant.
ANY benchmarks shows the same things: i3/rest of AMD CPUs for general (grandma doing email) usage, i5/AMD 8xxx for moderate gaming level, i7 for performance gaming (and best suited for R9/Titan cards so as not to bottleneck the GPU). That is the facts, look for yourself.
If someone got themselves a APU, they have really no choice, just as much as if they had a Intel i3 Clarksdale, a Intel Duo Core 2, or if they were using a Pentium 4 CPU, they would need to replace the computer FOR GAMING (not for other general uses) especially if they intend on any 2013 and forward games.
