Windows 7 RTM 32Bit vs 64Bit (with 4GB RAM)

Stick with the 64bit. 32bit is a dying breed. There is no doubt in my mind that Logitech supports 64bit. Make sure you have their latest official drivers installed.

That .5gb of ram may not seem like much now, but you will be kicking yourself later for reverting to 32bit.

This is quite an informative article on the subject. A couple years old, but i learnt a few things :

Please post or comment if you have better ones

I lost 1 GB just by sticking with Vista 32bit on one PC. If possible, always choose the 64bit version of the OS.

A lot of apps are starting to get 64bit versions which are normally faster, the OS feels more stable and you can actually access all your RAM.

i recently purchased gigabyte GA EQ45M-S2 (supports upto 16 GB RAM) and i am happy with Win 7 x64 with 8 GB (2*4gb).I dual boot xp and win 7 (both x64)and believe me i will never ever be using 32 bits. Very soon i will be upgrading it further to full 16 GB,as required by the work i do......... For now enjoying Win 7 x64........................ :)

And just stick with x64.We r gonna see a hell of driver support soon....... and we are alrady having :)

Cheers !
