"For several months now I've been trying to decide which new technologies I will choose for my next PC upgrade. It's a common problem for many people out there given how many major tech developments there have been in recent times, including Dual Core CPUs, PCI-E, SATA-II, SLI, Crossfire, and Windows x64 to name a few. I wanted the best I could afford, and I wanted to future-proof my system as much as possible. Finally, I just wanted a system which worked straight off the bat, without all those terrible incompatibility issues, bottlenecks and hardware glitches we keep hearing about from various setups. The results are in my Hardware Confusion article, and might help you make a better choice if you're looking to upgrade as well."
