Hello,

I just built a brand new machine for primarily gaming and was wondering if I should install 32 bit or 64 bit Windows 7 Ultimate. Will older games made for XP work on 64 bit Windows 7 Ultimate?
Would I benefit on gaming by increasing my ram from 4gb(DDR3 1600) to 8gb?

I am not worried about Drives, I have check on my printer, etc. All 64bit compatible.

I have alot of Win XP games that I still love to play, and wish to continue to play and I don't know if 32bit or 64bit matters. TOCA Race Driver 3 is one. For example my friend installed TOCA 3 on his Win 7 32 bit, and the only problem he ran into is he had to use a NO-CD patch to get the game to work. Which I prefer to do on games I own anyways. I also noticed he is maxed out on ram with Crysis; It uses all of the 2.75GB ram out of 4GB available on 32 bit. I have 4GB DDR3 1600 right now and wouldn't mind buying another 4gb if it is beneficial for gaming; which this machines 90% of it use will be. If it comes down to it I rather install 32 bit, if 64 bit is not compatible or has issues with older games.

Thank you.
 
Hi,

In my experience, you should be able to get most XP-era games running under Windows 7 x64. The built-in compatibility settings work pretty well. Also, Microsoft are busy rolling out patches to fix program compatibility, so if something doesn't work now, they could fix it in future.
 


The games that you run on XP would most likely be 32-bit applications, and as such, they could only access less than 4GB of RAM. If you plan to run more than one 32-bit game then the memory upgrade might be worth it, otherwise it may provide no perceivable difference.
