Vista\XP
2.4 ghz processor.
1 GB Ram
6 Gig Hard drive space
Nvidia 6800 or ATI x850.
That`s minimum. I really can`t say what the minimum is for smooth running. I mean who would know unless they had several grades of PC?
I can tell that with my Specs I play on FULL and have a smooth game.
My specs are:
Win 7
AMD Phenom II 955 Quad core processor (overclocked to 3.20, but probably not required).
4 Gig DDR2 Ram
Nvidia Gainward 260 896meg card.
Yeah, the current machine that is my parents has XP with a 2.7ghz single core processor, 4 gig ram, enough hard drive space, and a 512mb graphics card ( don't remember what it is and can't check as the thing is dead and the comp won't display anything on screen) That machine could only run on medium settings. It died because some idiot at some point put a 270 watt power supply in it and it needed at least 300watts. Apparently that can slowly kill the graphics card. It's time for my own machine now anyway.
I am going for this kind of power because I want to be ready for Skyrim when it comes out, but can't wait to build my computer until they put out requirements for the new game as I am unable to play computer games now.
So I am thinking windows 7, a quad core above 3 ghz, 4 gigs of ram(maybe 6) and maybe a 1024meg Nvidia graphics card of some sort(or 2 512s)
As far as specific hardware I have some buddies that went to college for this kind of stuff that can help me.
