What processors, in all the world, do you think is the best one to use for many different things.. (i.e. Which processors best for gaming, for Work, for Basic computer lifestyle, etc)
This is a personal preference answer when you ask this. AMD and Intel people will give you numerous reasons why their CPU is better then the other. In the end the decision is what is your budget and what how much is to much.
What computer build (more or less) would you recommend as a gaming computer, as well as accessories, of good value and quality?
Again budget budget budget.
How much are you willing to spend for the components?
Remember what you buy today will in reality probably be out dated in 3 months.
I spent 1500 last January building me a good all around system that would play games, movies and do office stuff also. Two months later there was new video cards, mobo's, hd's, cpu's out. The best lesson is to get something you can afford with the emphasis being on upgradabilty for later.
Most important I would never suggest a name brand system as I believe building your own system not only gives you the satisfaction but also you know every component in that system and how to replace it. The downfall is the manufacturers warranty on components is all you will have.
