here some info 'bout the world's fastes personal computer:
____
The Power Mac G5 is the world’s fastest personal computer and the first with a 64-bit processor — which means it breaks the 4 gigabyte barrier and can use up to 8 gigabytes of main memory. The new G5 processor — available at speeds up to dual 2GHz with a new ultrahigh-bandwidth system architecture featuring AGP 8X and PCI-X — makes the Power Mac G5 a breakthrough in desktop processing power. And models start at just $1999.
How fast is the world’s fastest personal computer?
The new Power Mac G5 throttles past both the fastest Pentium 4 and a dual-processor Xeon workstation when tested using industry standard SPEC CPU 2000 benchmarks — SPECfp_base2000 and SPECint_base2000 measure the speed of a single task — either a floating-point calculation or an integer calculation — executing on a single processor. The “SPEC rate” metrics, which recognize multiple processors, more accurately demonstrate the performance of a dual processor system. The results (see chart below) should make your pulse race just a little bit faster.
Ready for the real world
The PowerPC G5 processor dramatically accelerates performance in real world applications, too. When compared head-to-head against the same PCs, in a large series of Photoshop tests the dual 2GHz Power Mac G5 is 2.2 times faster than the 3GHz Pentium 4-based system and almost twice as fast as the dual 3.06GHz Xeon-based system. Additional performance tests reveal similar performance gains for professional music and audio creation, and scientific analysis of genetic research.
Bandwidth to burn
The Power Mac G5’s ultra-high bandwidth system architecture features a 1GHz frontside bus — one on each processor — for maximum throughput. And a point-to-point system controller lets data move directly between subsystems, without affecting processor function.
PCI-X expansion
The Power Mac G5 comes with three PCI-X slots, giving you the benefit of the newest advance in PCI technology. The PCI-X protocol is perfect for high-performance PCI devices, increasing speeds from 33MHz to 133MHz and throughput from 266MBps to 2GBps.
High-speed AGP 8X Pro graphics bus
Compared with the AGP 4X interface, the Power Mac G5’s AGP 8X Pro graphics bus effectively doubles the maximum transfer rate and doubles the amount of data transferred in a single AGP bus cycle. The 66MHz AGP 8X Pro bus strobes eight times per clock cycle, achieving a 533MHz data rate and a maximum bandwidth of 2.1GB per second — ideal for the ultrafast graphics cards it ships with, like the ATI Radeon 9800 Pro or NVIDIA GeForce FX 5200 Ultra.
FireWire 800, USB 2.0 and high-performance I/O
The Power Mac G5 ships with a FireWire 800 port and three USB 2.0 ports (plus two USB 1.1 ports on the keyboard). Gigabit Ethernet, FireWire, USB 2.0 and optical digital and analog audio are all integrated through two bidirectional 16-bit, 800MHz HyperTransport interconnects for a maximum throughput of 3.2GB per second.
Three powerful models
The Power Mac G5 product line comes in three muscular configurations — 1.6GHz, 1.8GHz and a dual 2GHz model. They all feature the legendary SuperDrive (DVD-R/CD-RW) as standard equipment across the line. And of course they come with two FireWire 400 ports, three PCI expansion slots, ADC connector, DVI connector, analog audio in, analog audio out, optical S/PDIF in, optical S/PDIF out, front headphone and speaker jack and built-in Gigabit Ethernet — all as standard equipment. All models are AirPort Extreme-ready, and offer Bluetooth capability as a build-to-order option.

and this is just the beginning!!! apple and intel will push the processor to 3ghz until the end of the year... then 2 of them in one computer.... that rules!!!!
