Regarding : This is a socket 775 board, but it is not compatible with all 775 processors. The Intel Q43 chipset does not support the older Pentium 4 or Pentium D NetBurst architecture. It is designed for the newer Core 2 architecture. However, Dell’s BIOS often locks out certain high-end CPUs that were not offered in the factory configuration.
This is the single biggest performance boost. The SATA 2.0 (3Gb/s) ports will bottleneck a modern SSD's maximum speed (6Gb/s), but even running at half speed, an SSD will make the system feel snappier than a mechanical HDD. Specification Component Model / Engineering Code E93839 /
