I have a Dell Optima 260 with 384 MB DDR RAM memory, a standard 20 GB IDE Hard Disk, a PCI Intel(R) 82845G/GL/GE/PE/GV 64 MB Graphics Controller, and the motherboard is the standard Dell Computer Corporation board for the 260. I want to upgrade the performance to bring the machine up to current standards and have $350 to spend. What are my best options in this price range? Thanks in advance for all help…
