So much to choose from, 3 rigs begging to be finished

so at the moment i have 3 rigs no the books needing a bit of thought put into them.

First off is the software dev and cad drawing machine.
This one are the remains of my last pc. At it's core we have a AMD FX-4130 and a Gigabyte GA-970A-UD3P (these are the parts i have so far).
Now since i never do CAD drawing i have no idea as to which Graphics card to get (this is the part I get stuck on the most)
Rest of the system will be roughly be 450w-500w PS, 4 to 8 GBs of ram 320GB WD blue HD and a fairly cheap case.

next is the Web surfing and light audio editing rig. (aka my fathers PC)
This is the one i am needing the most help with. As my father doesn't play games i have thought about going the way of an APU.
But I personally have never seen nor touch one let alone know which one would be best for my situation.
Is 1600MHz going to be able to keep up with basic graphics etc?
anyones insight into this is welcomed.

Last is my rig, The gaming rig.
Pretty basic, GTX 970 or GTX 980? and the 3.5GB vram issue isn't a biggy for me as i still play most games around 1440x900 or lower
And then Ram, Kingston fury or Corsair?

1: What CAD software are you using (or planning on using) and can it take advantage of GPU acceleration features (e.g. OpenCL or cuda)

2: Yes 1600Mz can keep up with the APU's, but 1866Mz is usually the recommended base.

3: 970 is most prob still overkill for that resolution and personally Corsair RAM.

@zanginator
From what i saw (while looking over his shoulder) i believe he is using turbo cad, not sure what version but it should be a later version.
The person in question does a bit of designing/development of locks, as he is NZs top locksmith but the system he uses the most, is a AMD 1400+

Ok, I know nothing about TurboCAD, and have never heard of it, best thing to do would probably to get a workstation card. Not sure how large of a model he works with though. From the sounds of it though, it won't be a very powerful rig anyways, so a very low end card won't stand out as a bottleneck.

I agree with the 1866 base, however if he isn't going to be playing intensive games with a ton of large textures, it won't matter. I'd look at price, and capacity, for a web/audio editing rig, capacity might be worth a lot more than speed. Audio, video and photos love RAM, and will always want more.

Holy crap a 970 or 980 for a 1440x900 screen. I'd say either one that you can afford, it'll last you a while, I just hope your CPU matches it.

Corsair ftw.

The work load won't be large that is ture but the more important part is the accuracy.
In this situation 1/1000 of an inch and smaller are the scales he'll be dealing with.

As fas as my fathers rig is concerned the most graphical taxing game he will be play is spider solitaire (no jokes).
The reason why I have chosen 1600MHz is at the moment I have a 8GB kit sitting in my pc which I am planning on swapping out once I have brought a 16GB kit.

Which brings me to my rig. The main reason for me playing games at a lower resolution is because of the lack of vram.
Will a FX-8350 be enough?

Ahh, for accuracy you'll want a decent GPU. But that depends on the software, I won't be able to help much further than that. I'm a Solidworks person, and Solidworks loves its Workstation cards. Hell, we have CAD workstations running off of APUs, An AMD A-10 6800K, 8GB of RAM, and after a while finally put a Quadro K4000 into it.

Stick with your 8GB 1600 kit, it'll be fine.

And FX-8350 with a 970/980, might be a little anemic. A 970/980 would match up well with a 4790k, if you can afford it.
