This is, generally, a good site. However, they've recently suggested builds using low-quality parts, and therefore the builds are unlikely to last long. Although more experienced people probably know this, people who are newbies at building likely don't and, if they follow the instructions from this site, may end up with a PC that doesn't last, thereby wasting their money. I wouldn't trust them - anymore.

Superb tech site, though not aimed at beginners; but because of the assumed level of knowledge of the reader, there is a great wealth and depth of technical info on computers and technology. Very thorough testing and benchmarks give very comprehensive info; when I'm considering a computer upgrade, I go here first to find out if it's worth doing.
