No the ultimage in for those with unlimmited funds wouldn't be a Raptor, it would be a i-Ram DisK which uses up to 8 GB of DDR memory to create a virutal hard drive. (Actually the 8 GB model may have been released yet )
And a Raptor is less than the price of a decent video card and will keep its value far longer.
Definately not the first item on your list when considering where to throw money at your computer to make it faster, but it does belong on the list.
