Hey guys,

I've windows vista installed on my system but its 32Bit would i notice an increase in performance if i installed 64Bit ?

My system is

Asus M4A78 AMD 770 (Socket AM3/AM2+) PCI-Express DDR2 Motherboard
Kingston HyperX 4GB (2x2GB) DDR2 6400C4 800MHz Dual Channel (KHX6400D2LLK2/4G)
AMD Athlon 64 X2 Dual Core 7750 2.70GHz (Socket AM2+) - OEM

also thinking i might upgrade my CPU to a X4 near the end of this month...

If by performance increase you mean will programs run faster ....

YES , if they are 64bit applications

No , if they are 32bit ones (running 32bit app on 64bit OS will run it a little slower than under a 32 OS )
 
You would most certainly notice a performance increase overall as the 32-bit version cannot address the full 4GB of RAM you have installed at present. The 64-bit version can however :)

Sweet , its good to see that Blizzard have released a 64bit exe for their game

I wish more game studios would do that

Yes, but the 64-bit files are larger than the 32-bit files, which means that the extra amount of accessible RAM is often negated.
 
Ahhhh , then it wont matter , its the executable that needs to be 64bit as well
to address more than 2Gig of memory

WoW wouldn't need more than 2GB anyway.

Besides, the system overall will be able to address all the RAM in x64, meaning your system as a whole should run a little better, even if specific applications do not.

Though myself I rarely game in windowed mode and
run other apps at the same time , but everyone is different I suppose
 
No it won't. The change between 32 > 64 bit is done in hardware on the CPU. There is no performance decrease.

Yep for executing native machine code there is a switch to toggle 32/64 on the cpu
BUT
If you are using windows API calls (as most programs do)
wow64 will have to take care of translating a 32 bit call

This extra layer will slow things down a little
