Imac running Windows 7
 

I have an 27 inch IMAC and plan to Load Windows 7. Should I use 32bit Windows 7 or 64bit Windows 7. I have copied my system below.iMac
Model Identifier: iMac11,1
Processor Name: Intel Core i7
Processor Speed: 2.8 GHz
Number Of Processors: 1
Total Number Of Cores: 4
L2 Cache (per core): 256 KB
L3 Cache: 8 MB
Memory: 8 GB
Processor Interconnect Speed: 4.8 GT/s
Boot ROM Version: IM111.0034.B02
SMC Version (system): 1.54f36
Serial Number (system): W80057165RU
Hardware UUID: 78EF870E-2E88-5820-A538-07A889A45D83

I would recommend 64-bit, 32-bit will not see all of your 8 GB of memory. Although I don't know about an iMac, maybe someone will advise the opposite.

64 bit
 

I ordered 64 bit Windows 7 for that very reason. Will Dangerous Waters play on the 64 bit Windows? I also have Silent Hunter 4 and hope both will run since they were designed for Windows XP. Thanks for your reply.

I think they both should work fine.
