Thread: Intel Core i7-920 and 32/64 bit OS

PC configuration
X6000B/PRO (X6279PGi): Core i7-920 / 6 GB / 1 TB / 896 MB GeForce GTX275 / DVDRW / VistaHPx64

X6000B/PRO (X6277PRi): Core i7-920 / 6 GB / 1 TB / 1 GB Radeon HD4890 / DVDRW / VistaHP x64

May I at this complete set 32 bit operating system? There is a need to use Windows Server 2003 32bit. I know that this OS does not support more than 4GB of RAM; this future system will be reinstalled on a 64 bit.

Or a 32-x is only valid
X6000B/PRO (X6275PRi): Core i7-920 / 3 GB / 1 TB / 1 GB Radeon HD4890 / DVDRW / VistaHP

In all 3 cases the reference to the processor is the same, but what is the difference? X6279PGi, X6277PRi, X6275PRi?

Server operating systems on a computer game. Maybe all the same configuration is better adapted to the Northern problem.
