CPU question

[Synyster Shadows]

So my Acer Revo 70 is a decent computer. According to the Windows Experience Index, the bottlenecking component is the CPU. It drags the base score from what would be a 4.5 down to a 3.9. I did some research and found out what socket type my motherboard is. But the question is, could I actually take out the CPU for upgrade? The processor is an AMD E-450 APU and, in my research, I'm only seeing it in laptops and such where it is integrated and cannot be upgraded. What about my case, though, where it's in a desktop? Would I be able to take out the processor and put in a better one? I'd really like it if I could upgrade the processor and get better performance out of my PC. Thanks in advance.

In laptops, most of the components are soldered in. In desktops you can most likely remove it, and if the new one that you want to put in matches the socket type, you shouldn't have a problem. You should also look into overclocking though. That would be a cost free alternative

The windows experience index is really not a good tool for benchmarking or determining performance. I'd say if it feels good and fast for what you're doing, stick with it.
But yes. The mobo socket type should work for all amd cpus of that socket type, so swapping them should work.
What's the socket?

[Synyster Shadows]

It's a BGA413 socket. Are processors with BGA413 sockets common? I'm new to this stuff and don't know a whole lot about what's common and what isn't, though I know some things.

From my experience, there's not a big possibility of switching out a CPU.

This is because there's little alternative that is compatible with the socket, which has a very good reason: it's all different.
You may want to put, say, a Pentium D where a Pentium 4 was meant to go(this is a general example, probably not your case), only to find that there exists no Pentium D's that will fit. In this case, it's probably the power use, as a Pentium D likely uses more power than a Pentium 4(as if that didn't use enough already), and even if you could fit one in, you'd likely fry the motherboard.
Other times it's the hardware, specifically the chipset having a different configuration, or more commonly the BIOS not being meant for it.

If it's a laptop, you're almost always stuck with what's in it, only sometimes being able to swap out or add in the RAM.

it may be possible to upgrade the CPU so long as the socket and chip set match. but so long as it feels fast enough for you there is really no point. and I have never heard of that socket beforee , I have spent many years wading through the relm of the PC but have yet to come across it. And trust me, the windows experience index are pathetic and reflect nothing. My rig has a score of 3.9 but runs minecraft and other games maxed out at 45-60fps. Granted the AMD e series are bad but again as long as your PC feels good enough for what you need there is no point.
