I have Vista on my Pc , once I get xp on there 2 will I be able to have both Vista and xp drivers for my video and sound card ?
If you dual-boot correctly, you will have two partitions on your hard drive. One partition will be for XP and the other will be for Vista. Each operating system will have it's own drivers and software that will have to be installed. In fact, if you have a 64 bit processor, you could have a 32 bit OS and a 64 bit OS.
