Building your own machine is pretty easy. The motherboard and case manuals these days show almost step by step how to connect things and there is a wealth of videos and forum posts on the Internet.
Building your own rig typically doesn't save you money. Companies that build and sell PCs get better pricing and also often economize on the actual components.
Building your own rig is more about being able to choose the exact brand/model of graphics card, cpu, cooler, ram, motherboard etc that you want. Also assuming that you have a decent case etc then you can just re-use a number of existing items including potentially your OS that in the end can save you money.
The hardest part of building a PC is deciding what components to use. A good site for background info is TomsHardware (
http://www.tomshardware.com). They have monthly guides of the recommended GPU and CPU to buy for what budget which are well worth reading as input into your decisions. Specifically look at:

They also have some useful tutorials such as:

The actual components you select really determine the price and there are some areas where you can save money in the short term, while other areas you may want to invest more in.
From cheapest to more expensive CPUs to consider include:
Athlon X4 750K
AMD FX-6300
Intel Core i3-4130
Intel Core i5-3350P
Intel Core i5-4670K
I would probably go for one of the two i5s listed above. Which you select really comes down to whether you want to overclock and which motherboard socket you want to settle on LGA1155 (IvyBridge i5-3350P) vs LGA 1150 (Haswell i5-4670K). This is really one of the more difficult choices as Haswell is the latest generation CPU and IvyBridge is the prior generation. Therefore if in the future you want to upgrade the CPU again you may want to go to the Haswell route as it is more likely to still be around although Intel is notorious for changing the motherboard sockets on a regular basis!
I would also go for a watercooling solution instead of a fan for the CPU. They are easy to fit, work well, and often take up less space and are quieter.
Getting a good PSU is also critical, once again there are many good guides out there. Which PSU you go for is determined by what GPU(s) and to some degree CPU you use. The more power hungry GPU the more powerful PSU needed.
If you are still unsure then TomsHardware also lists some example builds at different budgets which are a good starting point and can be modified to suit your needs e.g. for $800 and $1600 respectively.

Some suggestions/ideas to think of.
- RAM - go for 4GB if a 32bit OS, or 8GB if 64bit. More than that is not necessary. Also don't bother with the super fast RAM as it makes negligible difference. Unless you are a serious overclocker just go for something that is fairly cheap.
- CPU - If you can afford it go Intel over AMD
- GPU - many good choices, check the guide above. I personally like AMD Radeon however nothing wrong with Nvidia and which is best for a budget changes every month
- Cooling - go watercooled for the CPU. You can get something like the Corsair H60 or Antec 650 for ~$65, maybe less.
- SSD/HDD - Go for either a 64GB or 128GB SSD if you can afford it as they greatly improve boot time and game loading times. Don't need to go for the most expensive, something like an OCZ Agility 3 may be cheap now as they have gone bankrupt.
You may be able to save money by purchasing a bare bones upgrade kit if you can find one that has the components you like. Typically these expect you to re-use your PC case, keyboard, mouse, OS etc. Assuming you are in the UK then Dabs.com has a few and the following is a good set of items:
http://www.dabs.com/products/asus-4...geance-pro-black--8Y8X.html?catid=15005&src=3. I've not lived in the UK for ~7 years so I'm a little out of date on where to buy from, I used to look at Dabs.co.uk and Scan.co.uk many years ago for my baseline price and then use the search engines to see if anywhere was cheaper.
Finally you really need to consider what resolution you are going to play at. If it is a single monitor 1080p then no need for SLI/Crossfire which can save you a lot of money on what motherboard and GPU you go for. If you are looking to go for higher resolutions or multiple monitor gaming then your GPU costs will increase significantly.. e.g. from $250 to $500+.
I typically see the CPU/Motherboard/GPU as disposable assets, where the CPU/Motherboard lasts 3 years and the GPU likely 2 years (after which you replace or crossfire/sli).. That is just my perspective on this and really comes down to what games and resolution you play. Few games these days are CPU bound hence the GPU/resolution is a far more important consideration for getting a good performing system.
The Case/PSU/SSD/Keyboard/Mouse/OS/Monitor are more likely to be reused.
I wouldn't worry about a separate sound card unless you are looking to invest $100+ on quality headphones. The motherboard onboard sound is good enough, particularly if you are on a budget.
