Buying advice for acheap AMD desktop FM2 or AM3+


Hi, I'm looking for something that has decent on board hardware, can be BIOS flashed from off a USB stick and will work out of the box with the current fall distro updates.

I'm initially looking at something like an Asus F2A85-M Pro and an A10-5800K.

Would it be better to go with an AM3+ board and a dedicated GPU in the HD7670 or HD6670 range?

I'm going to have to point out how little I know about this question. I don't know anything about your location, so I couldn't give you an answer fine-tuned to your location, as I can have no idea what prices are like in your area. Whether that would really help is another matter, but someone who is in your area may also read this.

This may have a specific meaning to you, but if it does, say what you need. Or, maybe, you just mean a decent quality board generally.

Another option would be Athlon X4 740X or 750K. You lose a bit of clock speed, but not that much that it will be all that apparent in casual usage. Of course, if you have specific requirements, that might make a difference, but the 740/750 parts do give you the option of choosing your graphics card independently of the processor; useful, if, eg, you fancy was drawn to an nVidia card. Or, for some reason, you need better performing graphics than you can get integrated into something like a 5800K.

In some areas, it seems that the 740/750 haven't yet turned up, so availability locally might be something that you have to investigate.

I have to admit that I don't quite get the A85 chipset. If you are building an FM2-based system, you are presumably doing it to get decent performance at an economy price. The A85 boards that I have seen advertised around here (things may be different where you are) claim quite a premium in price over A75 motherboards, so that seems to make it hard to achieve the original objective as far as the price is concerned.

The Asus is probably the most expensive FM2 board available. The GigaByte F2A75M-D3H amd F2A85XM-D3H are about $50 cheaper (here anyway). The only advantages the A85X chipset has over the A75 is 2 extra SATA3 ports, the ability to run 2 PCIe 16 slots as 8x-8x Crossfire (rather defeating the purpose of a low cost energy efficient platform) and RAID 5. Not sure the latter matters under Linux as I'd be more inclined to software RAID even if the controller is supported.

Unless you want to overclock, you might be better of trying to find an A10-5700. They are only marginally slower than the 5800K but run a good bit cooler and use less power thus reducing other system resources needed (heatsink size, cooling, PSU capacity, airflow,...). Do note that the AMD APU's love fast RAM so that is a place not to skimp.

Well I should have stated that I was kind of wanting to tinker with Coreboot, it seems though that exceedingly few current generation AMD sockets are being worked on by that team. The board I picked was listed as being a Work In Progress for support.

That said, Coreboot support isn't a requirement, but a BIOS that can be easily flashed from USB is though.

I'm in the US. And yeah, I overclock everything, even when it doesn't need it or shouldn't be done...

Any modern board can be flashed from USB.
Overclocking an APU might not be a good idea, as results of overclocking may greatly differ on the use case, for example if you do a stability test with programs like Prime95 you will get higher stable overclocks as when you run a program that is heavy on 3D, since the video core is integrated into the CPU.
If you want to overclock I would always recommend a video device that is not CPU inbuilt, at least if you want to run software that is heavy on 3D.
