I'm running a: P4 3ghz CPU 3GB RAM 256MB Geforce 7300GT graphics card 80GB HDD on Windows XP, and it feels pretty bloated given how many patches and updates it has. I've also got on ongoing issue with the graphics card that only rears its head when I play games (it sort of distorts parts of the screen or makes text go missing or smear across the screen) that hasn't been resolved with the latest drivers or reinstallation. I was wondering given that I have a Windows 7 DVD banging about whether Windows 7 would work on my desktop at a satisfactory speed. The min specs are all fine or within reason, but obviously min specs only tell half the story. I found this thread that sorta half covers a similar topic: http://www.hardwareheaven.com/windows-7-forum/207716-how-low-can-you-go-old-hardware.html But it doesn't deal with recommended specs for Windows 7. I've heard dual core is a must, is this the case?
