Dual core is nice, perhaps even desirable, but not necessary. My PC has an Athlon 3700+ single core CPU which will run Vista with ease. That said, I do have 2GB RAM, a 256MB ATI graphics card and 3 HDD’s (1x250Gb SATA, 1x160Gb SAT and 1x200GB IDE) as well as 1x250GB external.
So I am more than blesssed for specs, esp disk space:D

Will prob upgrade again (sod dual core, quad core’s where it’s at) but not until the middle of next year at the earliest. At least thats what I keep telling myself…..;)

BTW, just got myself a lovley 20″ 4:3 (not widescreen) HP 1600×1200 TFT monitor….:D 😀 😀
