Go for 64 bit xp or vista?

[snowdog]

Hello!

I've just bought 2x1 gb Extra and have 4 gb total now, but my trusted xp 32bit pro only uses 3.12 gb. of it, should i get xp 64 or vista x64 as an extra os for dualboot?

Spec. in sig, main use for pc is gaming, followed by media&internet...


Also, how is vista oem with removing/adding ram and gfx, xp is whining about activation when I do those stuff (even when cpu&mobo are left alone)...



EDIT:
Also how would i go dual booting xp and vista x64 if i'd go for vista x64, ive read somewhere I can't start a x64 os setup in x86 windows, yes boot but what then, what stuff do I have to set etcetc. to keep my 2x xp.?

same with vista. some hardware it will not ask for reactivate. but for hdd, gfx, maybe ram it will..

just boot from the dvd and install it on another partition or hdd.. then the dual boot menu will be automatic made..
