This is touching a couple really touchy subjects on this forum...however I am really tired of repeating myself on every question I answer, so I am creating this in personal reference to link it to my question, if anyone else uses it, please do not blow up my inbox or message or respond to this in regards of arguing. Anyone that does will be reported, no questions asked. Again this is a personal use, if you want to use it great that is what it is there for, however I don't want any responses or comments that are not questions (not arguing questions either).

Front Side of Processors:

This is going to be the first thing you are going to want to decide on, this will determine what kind of motherboard and case you are going to need for your newly built computer. As for the breakdown on the processing units themselves:

AMD vs. Intel:

The primary difference between these two processors, regardless of which processor you are a fan of..is one simple thing, what are you using it for? For some people who are bias on either AMD vs. Intel you might get a different answer...this guide is created to give you the straight truth of these processors, and I am an AMD fan, yet I only run 2 AMD processors, and 3 Intel's (including my i7 extreme at work) so I will be able to tell you the truth on each processor.

The Processor's We will Be Discussing (There are obviously more out there but these are the main ones used):

AMD FX-Series
AMD A-Series (A6+ Processors)
Intel i5
Intel i7
Intel i7 Extreme

Things you Need To Know About Processors Before-hand:

Hyper-threading: (Split-core is what I call it) This is an Intel based only feature, in which the processor has a certain number of physical cores and each physical core is split virtually into 2 separate cores. For example (I know its confusing), if I have an Intel i7 that is a hyper-threaded 4-core processor, I would have 4 cores that are physical and 4 cores that are virtual, thus giving the impression (as far as windows can tell) that you have 8 cores. But again remember that you only have 4 physical cores. Note that the i5 does not come hyper threaded.

So whats the difference between all of these Processors?

AMD FX Series: The main reason people use the AMD FX-series is for the fact of that it supplies more physical cores then any other processor (FX-6xxxx supplies the same amount of physical cores as the i7 Extreme). The FX-8xxx series provide 8 total physical cores and no virtual cores (so kind of what you see is what you get kind of processor). This is beneficial for multi-cored programs, that use 5+ cores. Anything that uses four cores or less would be better ran on an i5 processor since it does not have to carry around the extra cores.

AMD A-Series: The main reason people use the AMD A-series (A6+ Processors) is for the fact that they come with integrated graphics (most laptops that run AMD use these, they also do not need a separate stand alone graphics card) and are considered a quad core processor, while no where near as powerful as the FX-series, they do provide a very good budget processor, while giving you four (quad) cores.

Intel i5: These processors are exceptional at running games. Since most games do not use more then 4 cores, and Intel generally surpasses AMD in performance as well these are the gamers choice of processor. This is true because of the fact that most games and programs do not use more then four cores as it is. These processors are faster since they do not have to carry around the extra cores like the AMD FX-series do, thus making them faster at a lower base GHz.

Intel i7: (The business processor as I call it) This processor is used in most business's that use a lot of power behind their processor. While it isn't as effective as the i5 at gaming, it is more exceptional at programs that use 4 cores heavily. Again this processor supports hyper threading, so you have 4 physical and 4 virtual cores for a total of 8 cores according to windows.

Intel i7 Extreme: As I said before this is similar to the FX-6xxx series since it also uses 6-cores vs. the regular 4-core i7. This processor is extremely powerful, since it has 6 physical cores and 6 hyper threading cores. I would only recommend this processor under really extreme usage. So Windows will think there is 12 cores with this processor.

So How Do I Compare Them (Which Should I Chose)?:

The truth of the matter is...you can't compare most processors like you can with sticks of ram or cases, the truth isn't very black and white for the comparison chart of processors. However there are things to look at before you decide on which processor fits your system and I will go through them here.

Budget:

For most people on a budget the AMD route is going to be the way to go, however if you are a gamer I would normally recommend an i5 route, or if you really don't have a budget set, or want the best overall performance (depending on what its for) I would recommend the i7.

What Are You Using It For?

Gaming:

The i5 is comparable in gaming to the AMD FX-8350, however the i5 will out perform the FX-8350 since it does not have to drag around the extra cores (cores 5-8) that the FX-8350. Besides that fact most games do not utilize (or fully use) more then a quad (4) core processor. As a matter of fact most games have enough trouble using a quad core as it is. It is true however that the newer agriculture structure of the AMD FX-8xxx series smooths out performance on the first 4 cores, using cores 5-8 to smooth out the performance, however it still get out performs by the i5.

Video/Music Rendering/Encoding:

For any video or music rendering or encoding, the AMD FX-6xxx or FX-8xxx is going to be your choice of processor, since it has 6-8 physical cores, it will have a lot smoother operation under the stress of the video/music programs using multi-cored programs (not to be confused with mufti-thread). This is also true if you are going to be using any programs that rely heavily on multi-cored processors (5+ cores), which 95% of programs and games do not at this time. This will heavily outweigh an Intel hyper threading since AMD processors can focus the same amount of usage across 6-8 cores rather then twice as much usage on 4 cores (remember Intel i7's only have 4 cores, unless its an extreme, and even there the same holds true).

3D Rendering/3D Animation:
A would recommend either i7 processor for this, since they are going to be a better overall performing processor then the AMD FX-6xxx or AMD FX-8xxx series processors. These processors while they have a lower core count, they make up for it in speed (having 4 cores vs. 8 cores to drag around and using the hyper threading to make up for the lost physical cores), for this reason they can put a lot more pressure (usage) on 4 cores then the AMD FX-6xxx or AMD FX-8xxx series can.

i5: Gaming processor
i7/i7 Extreme: 3D business/3D Rendering processor
AMD FX Series: Multi-core programs
