Here it goes:
I've built a machine that is 64 bit supported. (Athlon 64, all drivers and so)
I'm using XP (32bit)
My HD is configured with 2 partitions. (3 if you count the 8 MB one)
I have recently obtained Windows XP Pro 64bit.
My question is: Will I gain any (gaming) performance increase by installing 64 bit OS?
Bare in mind that this machine is used for gaming only.
Cons I've learned so far are:
- lack of support for 16 bit applications (old games)
- questionable compatibility for 32 bit applications (new games)
- xp Pro 64 bit is based on windows 2003 server, which is more than needed for my machine (simpler OS - less strain on system)
Acctually, there is only one reason I'm even thinking about 64 and the reason is some test I ran on my system. The test was to determine how well will battlefield 2 run on this system and results were great. Only negative result was the OS not being 64 bit.
I'm reluctant to install new os 'cos I'm not sure will those 2 come in conflict with each other. I imagine that both systems will try to use same system folders ("Program files", "Documents and settings") thus renderind 32 bit XP corrupted upon 64 bit OS installation (i.e. overwritting registry files at "documents and settings/user", "Program files/common files" etc.).
Somebody else's expiriance at this field is welcome.
