Dear Lifehacker,
My computer is getting a little old. I built it myself, but I'm not sure whether it's worthwhile to upgrade individual things like my processor or video card or whether I should just start from scratch and build a new rig.

Dear Lifehacker,
I'm building my first computer using your guide, and I've been asking around on forums for help on picking the parts. I was using an AMD processor, but everyone keeps telling me Intel is better. Should I listen, or are they just fanboys? Does brand matter? » 7/09/13 9:15pm 7/09/13 9:15pm

Well we are now sufficiently down the line, as NVIDIA has released the first of many… » 8/12/08 11:20am 8/12/08 11:20am

Anyone into computer gaming knows NVIDIA is one of the biggest names in video cards today, but imagine being new to PC gaming, knowing nothing at all about video hardware, and wandering into a Best Buy to try and determine which graphics solution suits your needs. It's like being a man sent to the grocery store for… » 5/07/08 11:40am 5/07/08 11:40am
