What is that R1900 gonna give you that you don't currently have?
Prettier graphics? Huh? Slower application performance (Tom's Hardware)?
Get Vista with a new PC/Laptop but atm stay put with XP. If you have
R1900 to throw away for pretty graphics maybe consider upgrading to
a prettier monitor instead, a 24 inch HD computer monitor can be
had for R8000 now. A 30 inch HP (best atm) can be had for R14K
that's only R12K left to go. I know what I would do with R2000 cash
if I had an extra 2K lying around doing nothing

and was a graphics
freak
