AMD's first Quad FX processors have now hit the shelves and are available for purchase at retail outlets. While we all know the cost of the FX processor in general is high, the Quad FX is absolutely outrageous, and boards with chipsets that support them aren't easy on the wallet either. Starting with the Athlon 64 FX-70, expect to throw down around $550 for the retail CPU and another $400+ on a compatible motherboard. Unfortunately, these high prices don't bring much more than additional cores, with a CPU reworking still on the horizon for AMD. However, at a whopping 3GHz, they definitely will not disappoint in the performance department. Hopefully, the extreme cost of these CPUs will not be a permanent issue, as the Core 2 is beating the FX in many areas, including price.
