This is what I feel is the current landscape…
Processors – AMD’s newest "Phenom" CPUs boast native "true" quad-core technology, while the Athlon 64 X2 6000+ 3Ghz processor holds "King" title (until the former comes to market).
Intel is launching its newest "Penryn" Core 2 Duo and Quad procesors, while its Core2 Extreme Quad Core QX6850 3.0 Ghz 1333Mhz processor currently holds "King" title (until the former comes to market).
Chipsets – Intel has launched its new 3-series chipsets as well, which provides a 1,333Mhz bus speed, DDR3 memory support, and (my favorite) PCI 2.0 which doubles the bandwith for peripheral cards such as the next generation of graphics cards.
Graphics Cards – NVidia has its GeForce 8800 GDDR3 platform which sports a 768mb Ultra version. ATI has released the HIS Hightech Radeon HD 2900XT 1GB GDDR4 which also offers an HDMI output.
Sound – Creative Sound Blaster X-Fi 7.1 surround, 24-bit
Memory – DDR3 Dual Channel PC3 1600 (PC3 12800) has recently replaced DDR2. DDR2 Dual Channel 1300 memory (PC2 10400) was king.
I/O – SATA2 3.0Gb/s w/10k RPM drives will be the best , PCI 2.0 is also ungodly fast compared to the previous version.
Peripherals – 20x DVD burners w/Lightscribe, 32gb+ Solid State Hard Drive, USB 2.0, 5ms or quicker response flat panel monitors(x2), 1,100 watt power supply, Dual-Layer Blu-Ray and HD-DVD burners
Processors – Intel has recently released a Core 2 Extreme for use in laptops which will replace its current top offering of the Centrino Core2 Duo T7600 2.33Ghz 677mhz FSB. AMD offers the Athlon 64 X2 TL-66 3.0Ghz as its top prize.
Video – NVidia GeForce 8700M GT 512mb GDDR3 Dual SLI. ATI Mobility Radeon HD 2600 XT.
Memory – DDR2 Dual Channel 677Mhz seems to reign in the laptop world.
Sound – 7.1 channel hi-def
Other – SATA2 3.0Gbs, USB 2.0, DDR3 or Max DDR2, 32gb+ Solid State Hard Drive, Dual-Layer Blu-Ray and HD-DVD burners
