Yes we see a claimed %58 in a crossfire rig, but as another site claims it seems Mantel "shows itself most dramatically when you are in a heavily CPU limited environment."

Cant wait to see how much benefit this brings to Kaveri, as unless I'm having a senior moment from what i can tell the CPU part of Kaveri is what is letting it down in terms of FPS.

In Battlefield 4, we have more robust information. AMD claims that the FX-8350 + R9 290X will see an average of 23.8% better performance under Mantle, while the Core i5-4670K + 290X will see a performance improvement of just 7.5%.
AMD stresses that Mantle works best when a game is CPU-bound, not GPU-bound if a game is GPU-bound, it tends to stress the card to such a degree that Mantle-like optimizations will not help much at all. That said, those who will see the best benefit of Mantle will have modest PCs

Harlequin is also right; I didn't check 2,400MHz prices but in the UK I was able to find 2,133MHz kits that were just £1 or £2 dearer than £1,600MHz ones. DDR4 is coming and manufacturers need to shift the higher speed DDR3 kits.
It depends what you mean by basic office tasks, but while I won't argue that single threaded performance favours Intel's processors, I would say that the entry level experience doesn't rely on CPU-intensive tasks.
The best bandwidth is apparently achieved when Kaveri APU has both memory channels populated by 2-rank memory modules or with four single-rank modules, depending on what you can get your hands on.
