Thanks for the comments, everyone. I don't consider myself a power hardware user. Looking to transplant my P3/500 (Slot 1), ATI Rage 128, SB Live, DXR3 MPEG decoder, 3Com modem, and a bunch of USB devices--scanner, UPS, simple digital camera; keyboard and mouse, perhaps.
My current system has a 100MHz bus. 128MB RAM (SDRAM, I think). Will there be any issues transferring the processor, memory, or equipment--especially with the Asus P3V4X?
From what I've read, I won't be able to run the bus at 133MHz...not without new memory, anyway.
Being a system-level hardware novice, I appreciate your patience and any comments! ;^)
