- I think 64 willbe the future, so any reason NOT to get it?
- I guess with older games, which I like, XP-Mode from the W7 Pro version comes is really important?
As for XP Mode it actually isn't particularly suitable for gaming because it lacks 3D acceleration and does not support the 256 color display mode some early games require. These limitations can be partly solved by running XP Mode through VMware Player (free), but even it doesn't have full 3D support yet. XP Mode is just a pre-installed virtual machine, not some magical compatibility layer; if you have a suitable XP license you can install that in a virtual machine manually to achieve the same result.
The majority of games will run just fine natively, of course, and those that don't will probably have some fan patch or other workaround. GOG releases will also generally work (even if not mentioned on the store page) except for a couple of rare cases mentioned elsewhere in this thread.
Exactly the info I was looking for.
Will get a a new hardware & no older/ problematic hardware attached.
