bustr.....believe it or not newer soundcards have their own memory if I recall correctly.
Their impact should be nil.
I do know this....when using soundcards I used an SB live. I upgraded to an SB Audigy ZS or X.
When I installed the new Audigy it would not work properly...I tried updating drivers.
I tried everything to no avail. I had to uninstall the Audigy and re-install the SB Live.
Then......doing a search found out for a fact that the Audigy and Via chipsets did not get along.
Some problems with adding hardware aren't advertised or known for that matter.
Every PC and it's set-up differ. Drivers, chipset drivers, etc. can cause problems when installing
new hardware. Sometimes we just have to fiddle around to try and make it work.
Sometimes they just won't be compatible. A way of life in the PC world. <shrugs>
