I think you're overplaying it a bit. 64 bit applications do consume a little more memory than 32 bit apps but it's certainly not double.


I never said that. The memory for the instructions is double.
A 64-bit word is double that of 32-bit and whether or not you're using all the bits, that memory space is still allocated.

I tried x64 Win 7 on an early Core 2 Duo with 1GB of RAM, and the performance was pretty bad. x86 was better since more memory was freed.

However, the memory USAGE of the application itself is not double - and what was the hardware in question? (One thing that has to be taken into account is badly-written or piggy drivers - while not as large an issue as it used to be, it's still an issue, especially for lower-tier hardware and peripherals.) Given identical loadouts, what's the memory usage comparison between Firefox, PaleMoon x64, and Waterfox? One reason I prefer IntelliPoint Pro (and now the Microsoft Keyboard and Mouse Center driver for Windows 8) to SetPoint for my Logitech V220 is due to SetPoint's piggishness - a porky driver that is less usable compared to an alternative gets replaced by that alternative without a quibble. Love the V220 as a wireless mouse physically, but I loathe the porkiness of SetPoint.

I've run Win 8 on older hardware, as long as the CPU supports it, needing NX bit as I recall, I see no reason to not install it. If you're running under 4GB RAM then I'd personally install the 32bit version but that has alwasy been a personal preference to ensure I'm able to take full advantage of all my system RAM. I've personallay seen a big performance improvement with Windows 8 on older hardware that was previously running XP.

I don't see why it would be a problem. Windows 7 64bit runs awesome on low powered systems, even with aero enabled,
and supposably Windows 8 requires the same specs or lower.
Should work even better than XP anyways, as long as the hardware is compatible.
I'm even thinking of picking up some old piece o junk pc just to try Win 8 on. Wouldn't want to install it on a good computer.

Pointers and such will be double the length, but that's basically it, the actual stuff stored in memory will be about the same.

Edit: And when using 64bit, SSE/2 support is guaranteed, unlike 32bit mode.

If you love your old PC, treat it with great care, and put an OS on it, instead ;)

You're right, that does sound bad.
Was it working well with Windows 7 32bit? I'd leave that on it and enjoy. (Y)
