The problem with the A10 K series is not the TDP, not the iGPU performance, not even the price of the CPU, or longevity.
The problem is A85X motherboards, A75, and A55 being new so they carry a price premium. There's no clearance sales or quarter end sales yet. When microcenter gets them and we can get sub $200 for CPU and motherboard then it would be nice ($100 A85X mobo - $50 combo + $120CPU = $170, $80 A75 mobo - $50 combo + $120 CPU = $150).Examples:
GIGABYTE GA-F2A85X-UP4 $130
ASUS F2A85-M PRO $125
BIOSTAR Hi-Fi A85W FM2 $95 + 7 shipping = $102
The A55 stuff is ~$70, which is more than H61 boards (there's an MSI board for $55+7 shipping, which is out of stock though). A75 is where it's at I think, the boards are ~$80 and if you're buying an APU I don't see why you would put two GPUs in it for Crossfire unless bitmining.
In comparison, i7-3820+X79 = $350 or so , i5-2500K+Z68/Z77 was $250 or so.
When Vishera comes out later on then we ought to see the FM2 socket prices drop a little because they won't have that price premium. See the Z77 motherboard pricing now ($50 or so cheaper, compared to new i.e. asrock Z77 extreme 4 for $130 with 8GB RAM) even though they are "current".
I priced out a lower end A10 / A8 and it would cost as much as a i7-3820 build ($800-900). It's not economical right now.
I think A85x may be a waste, when the A75 has USB 3.0, SATA 6GB/s. Crossfire support on an APU platform makes the APU redundant, no?
In reality, the A85X Platform changes little. The key difference bet the A85X and the A75 chipsets is the number of SATA and USB 3.0 ports it natively supports. The A85X supports eight SATA 6Gb/s ports and four USB 3.0 ports. Granted, the A75 supports four USB 3.0 ports as well, but the A55 chipset doesn't support any at all.
This makes A55 a bad buy, a well-built A75 a pretty good bargain.
What annoys me is how it can't pair with a HD 7750 (HD 7750 uses less power than HD 6670.)
A10 can pair with HD 6670, A8 can pair with HD 6570 for dual graphics.
