I am looking to build a new gaming PC with an RX480 GPU. Will the RX480 run decently in PCIe 2.0, or will I be forced to get an APU with PCIe 3.0? I also plan on using CrossfireX.

Nope... If you stick with a all amd build, and the graphics card and apu both use the same driver family you can keep the igp enabled. However the whole apu has a wattage budget so the cpu will not have a high overclock with the igp enabled.
(Currently i have my igp disabled so my cpu portion runs at 3.56ghz instead of 2.6ghz) I have also switched to a GTX680 and GTX670 physx\cuda\open cl card.

Yes the A6-3650 Llano has 2 compute units.
I actually mined with them back in the day, my apu worked and paid for itself. So they are real and actually can do real work. Bit mining died and now would cost more in power than you make. There was that one golden winter where i partly heated my house+paid for my gaming system+some extra money...

pcie 2.0 vs. 3.0 doesn't matter until your messing with top cards like the GTX1080.

The FX8370 has 8 cores while the A10 has 4 cores. So basically the A10 has a FX4350 built in.
But the A10 has a fairly fast gpu that adds 8-12 compute units that work for open cl and HSC, and they promise Vulcan and DX12 will allow it to be used more in the future.

Both suffer from the same fate. Games rarely use more than 4 cores or threads, and almost none use open cl or the compute units for extra power.
So both run mostly as a quad core, most of the time. Some games can use 6 or 8 cores however so sometimes the FX8370 is ok.

I would go with a i5.

Do you need the OS system? That changes the price and what is worth using or not.
If you need the OS, some Refribished or used systems that include windows 7 64 or 10 are much cheaper.

Does it have to be CrossfireX? Because sticking with a single gpu is easier and cheaper as many boards do not have crossfire support. Especially if your messing with oem stuff. The GTX1070 is about as fast as two RX480's. Yes it's more money, but you save by getting a cheaper board or system.

I think you are misunderstanding what the compute units are. Either that or are misleading with the use of igpus with dx12 multi adapter support which in that case any gpu, even intel, can be used. They are clusters that any modern gpu architecture has so you don't get extra compute units. As with almost every dgpu setup, the igpu is disabled and not used.

-Install a new gaming power supply, maybe a case fan or two, a new GTX1070.
-The E3 1240 is a sandybridge quad core, It's basically a i7-2600.
-The RX480 would likely work with the oem power supply as it's a fairly low wattage card. You might need those molex to pcie adaptors.

-Please note that actual gaming benchmarks are quite different than the futuremark scores with the older i7-970 and most amd cpus doing much worse in actual gaming.
As you notice the FX-9590 4.7ghz 8 core cpu that is AMD's top cpu model, gets left behind by this Xeon workstation cpu.

There was that one golden winter where i partly heated my house+paid for my gaming system+some extra money. It was the winter of 2012. Since Feb 2012 mining with a gpu no longer makes any money.
The pair of HD-7850's have 1024 shaders that make up 16 compute units each so they did the bulk of the mining.

Actually here it has the chart with compute units. It has 8 compute units from the gpu portion and they add the 4 cpu cores.
It's supposed to be a 12core. If that actually worked it would kick the 10 core i7.
They also claim a whopping 1tflop in speed, if games ever can use that it would be so great.

I never said they can't do work. I never said they are not real. I never said you can't have both igpou and dgpu on. Actually they don't even need to be the same family and you can still have yours on with nvidia. They just don't help in games which is what the topic is about: gaming. That is changed with dx12 multi adapter but there are no games with that with the igpu. We already saw demos with even intel igpu + nvidia dgpu. And we all know about dual graphics with amd but we also all know that it's not good enough for high end gaming. So as I said, most have the igpu disabled.

It looks like you understand that gpu cores make up a cluster(compute unit) but it seems you think you can compare a cpu core to a gpu cluster. Gpus cannot do what cpus can and is why they are separate and cannot be added for "12 compute cores, 4 cpu+8gpu". Cores are not created equal and in this case there is an even bigger disparity between a gpu cluster and a cpu core. If you want to add gpu+cpu compute performance then you can do that on any pc with any cpu and any gpu. But do we count them together? Not except for amd apus because marketing. Amd marketing has done a great job to mislead people.

1 tflop would be so great? I think you don't realize that is less flops than a single 250x. That makes sense since the igpu is weaker than that and cpu cores don't add much.
