Both AMD and Intel are excellent CPU makers. AMD is less expensive and they make some very good processors, Intel does too.
I was an AMD guy for years and this last build I went with Intel because I do lots of video processing and editing, which Intel does just a little better and faster.
Be sure to get a good quality motherboard, that's the heart of the system. ASUS, Gigabyte, DFI LanParty and MSI all make very good motherboards.
I'm partial to Gigabyte, but that's my opinion. Stay away from ECS and Biostar.
A good power supply is a definite must, The ones mentioned in the previous post are all top-notch quality power supplies. I happen to use a Bgears Tarantula which is another top quality PSU. It got very good reviews on the sites I checked.
Cooler Master, Muskin, and ThermalTake are also good.
The PSU should be at least an: ATX12V / EPS12V 80 PLUS BRONZE Certified Power Supply. Try to get one that is a modular design, which means that you only need to hook up the power cables you actually are going to use. Makes for a much cleaner install and build with no unnecessary cables in the way.
Go to review sites such as AnandTech, Legion Hardware, HardOCP, Overclocker's Club, TechRadar UK, Hardware Canucks, and so on. Read the reviews and make your decisions accordingly.
If you need any more help or guidance feel free to ask at anytime.
