I'm one click away of buying Intel I7 Ivy Bridge 3770 3.4Ghz Gaming Pc Computer 1tb 16Gb GTX 550 Ti 1Gb Z11+ the computer is without Windows but I have extra copy of Windows 7 Home Premium 64bit.
The thing is that I discovered there is limitation around physical memory on Home Premium 64 (it allows up to 16GB RAM , Windows 7 Professional 64 and above up to 192GB). Ram of this computer is 16GB (Vengeance 1600MHZ DDR3) so I hope that it wont be a problem. (please response if you know about any other limitation around RAM I'm not aware of)
The thing I want to ask: If there is some other limitation on other hardware for this computer with Windows 7 Home Premium that I'm not aware of
...and is there any other reason for me to buy Windows 7 Profesional (or Ultimate) from hardware performance perspective? The computer will be used only for 3D modelling and rendering, no LAN work or super security
(I can upgrade W7 any time or buy it later, it's just I can have few pounds discount now, but if there's no reason I wont)
