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

After all of the complaints about the original game's outrageous system requirements, developer Crytek promised that this side story would be tweaked to run well on a much more affordable…

Graphics card manufacturer NVIDIA bought PhysX cards creators AGEIA back in February, promising a free upgrade to existing GeForce 8 and above cards using their CUDA (Compute Unified Device Architecture) interface down the line.

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
