Interested buyers of the Dimension 4550 and 8250 will be able to build their own systems using Intel's Pentium 4 processors at speeds of up to 2.8GHz, and various graphics cards from ATI Technologies and Nvidia. High-end 3D games and video editing are two of the most processor-intensive applications for PCs, and those users look for as much processing power as they can afford.
The 4550 will use Intel's 845PE chipset, which Intel will announce today, said a Dell spokesman. It supports faster memory, DDR-333 (double data rate), than Intel's other 845 series chipsets, which support up to DDR-266 memory.
Both PCs are built from the same minitower chassis, with the 4550 offering six USB (universal serial bus) 2.0 ports, and the 8250 eight USB 2.0 ports.
A sample configuration of the 4550 with a 2.4GHz Pentium 4 processor, 128Mbytes of DDR SDRAM (synchronous dynamic RAM), a 20Gbyte hard drive, and a CD-ROM drive will cost $869 (£555), Dell said in a statement. The 8250 costs $1,379 (£880) for a sample configuration with a 2.66GHz Pentium 4, 256Mbytes of RDRAM (Rambus dynamic RAM), a 40Gbyte hard drive, and a DVD-ROM drive.
The two new PCs will replace Dell's existing Dimension 4500 and 8200 PCs.
