It all depends on what exact CPU speed you have and what game you're trying to run. Myself, I have a P3-1Ghz which is good enough to play point and click adventures, etc. Most action games are pointless unless the frameskip is high and then you're skipping animation which you're more likely to notice in that type of game!

I remember a friend had one of these and it worked ok, but in Windows 98's DOS environment. From looking at the FAQ for the Santa Cruz, it appears that the Soundblaster compatibility in DOS does not work with Win 2000/XP.

Q: I have the Turtle Beach Santa Cruz in Win XP, and I cannot get it to play
sound on games that use Sound Blaster. I read the help section that said
I need to use the Legacy DOS Game Device, however I do not have the option of using this device on my computer. I tried to reinstall the software but
I was not able to find a way to install the Legacy DOS Game Device. Could
you give me a detailed procedure to get this option onto my computer?

A: That option is only available in Windows 98. You must use a VxD Driver
in order to have Legacy DOS support. So, XP, 2000, ME will NOT have this
option.

You have installed VDMSound, have'nt you? VDMS will give you sound with your DOS games. As long as you have sound in Windows, you should have sound in a DOS game in Windows 2k/XP with VDMS.
