Currently developing with VS2005, i'm due to change my development machine shortly.

Ideally I would like 8 Gb+ Ram in the new system, but i'm aware that 32 bit OS's can only support 4 GB. So I was considering getting a 64 bit machine to support higher amount of Ram.

Could someone please tell me whether this is likely to cause a problem developing software to run on 32 bit machines?

Thanks
