Any advice given (even if and i5-760 is a good choice) is highly dependent on what you are going to use the computer for.
There's a world of difference between a high-end game computer for the latest and hottest games and a computer that you only use to browse internet, send and receive a few mails everyday, and write some documents with MS Word 2003. Those are uncomparable.
You might need a computer of the first category. Or - like me - you might only need one of the last.
I want to try a home build(building my own computer), I'm looking for advice on parts(motherboard/GPU(graphics card)/Type & amount of memory. I will be using a i5-760 2.8GHz CPU. A few things, I won't be overclocking it & I will be using one GPU.
