So after taking into account things people have suggested and researching, this is what I've settled on:
CPU AMD A6-5400K APU Dual Core Processor Socket FM2 3.6GHZ 1MB 65W
Mobo ASRock FM2A75M-HD+ Micro ATX FM2+ Dual Channel 1XPCIE3X16 1XPCIE2X1 1XPCI 6XSATA3 USB3.0
RAM Kingston HyperX KHX1866C9D3K2/4GX 4GB 2X2GB DDR3-1866 CL9 DIMM Dual Channel Memory Kit
I definitely like the idea of iGPU and being able to cross it with a GPU without needing the hard-to-find Mobo. Plus, it's a cheaper build than the original and the iGPU will easily outperform my current rig. I can upgrade the CPU later, attach more RAM, get a better PSU (getting a cheap one from Kijiji) etc.
So, does this look like a decent rig until I get a better job? Thanks for everyone's help
