Just upgraded mine last week, very similar to Silverblades, I did this upgrade specifically for Vue, it will run on less but I like to use the "Poser Shader Tree" which needs a big pc with plenty of RAM.

Asus P5K-E Mobo, Core 2 Quad Q6600, Nvidia 8600GT graphics, Antec 900 case, 650 Watt PS, 8 Gig RAM, 2 x 320 Gig HD's in Raid 1 array [mirrored so no data loss if one dies] and against my better judgement but better than I thought it would be, Vista Ultimate 64!

Injustice will be avenged.
