I won't comment about upgrades because I never use AMD chips, but I will confirm that Vickie 2 is a memory hog. She's a greedy little wench and wants as much as you can throw at her. Obviously her baby sister (V2P4) isn't as greedy. If you load Vic2, then add high res textures (like those on DAZ or some of the others from people like Catherina and Syyd), plus transmapped hair and clothing (either plain or transmapped) then yeah, without some real muscle in your system it's going to grunt. If you are upgrading anyway, I don't see any harm in grabbing Vickie2 before the sale ends and before your upgrade. Even if you won't be able to play at length with her, it'll give you a chance to look and fiddle with this amazing model. I'd happily jump up and down and encourage you to buy her, but that wouldn't be entirely fair. I have a fairly powerful system to play with so I'm kinda biased. :)
