Piledriver, RICHLAND or Haswell

So its been three years since I got my pc and its time to upgrade my cpu and mobo.
My setup was:
cpu: i3 540
mobo: foxconn h55mxv
ram: 4gb
psu: thermaltake 450watt litepower
gpu: Sapphire hd6670 512mb ddr3

and I want to upgrade my mobo and cpu to one of the following:

mobo:ASUS M5A78L-M/USB3
cpu: fx 6300

or
mobo: MSI FM2-A75MA-E35
CPU: AMD RICHLAND A10-6800K

and lastly
cpu: i3 4340 or i5 4430
mobo:MSI H81M-P33

Now I know the other processors would offer better performance but i'm looking at getting the A10-6800k to crossfire with my hd 6670 for better gaming.

for this combo, you should go with a 970 chipset motherboard like asus m5a97 r2.0 or asrock 970 extreme 3/4.

or
mobo: MSI FM2-A75MA-E35
CPU: AMD RICHLAND A10-6800K

upcoming kaveri apus support socket fm2+, richland a10 6800k apus are also compatible with socket fm2+. in this case, a socket fm2+ motherboard with a88x chipset will be better. those motherboards are already available.

and lastly
cpu: i3 4340 or i5 4430
mobo:MSI H81M-P33

this is the second best combo after fx6300+970 motherboard, and will likely sustain most of it's gaming performance for a while (the core i5 more than the core i3).... as long as you don't get bored with the bare h81 chipset motherboard. in that case, a b85 chipset motherboard will be better.

Now I know the other processors would offer better performance but i'm looking at getting the A10-6800k to crossfire with my hd 6670 for better gaming.

amd dual graphics (cfx'ing apu with discreet gfx) is still hit or miss, leaning towards miss.

you could also start by buying a new discreet gfx card (e.g. radeon r9 270/r7 260x/ 7770/7790) instead. that one is gonna boost your gaming performance the most.
it all depends on your budget though.

Those setups I listed are all my budget allows. I can't upgrade my gpu because i'm selling my mobo+cpu to upgrade so the things I listed are all I can get. I'm fine with not having all the features like I don't care abou usb 3.0 sata 3.0 or pci e 3.0.
