Lets see i used carrara 5 pro with no graphics card on dual AMD 1gb mem, took ages render but could render large scenes no probs, got 7600 card now.
Poser 7 bugs lovely bugs and as for VUE 6 bah kept crashing on scenes that carrara could render, and forget oh ya need 4 gb min memory for Vue as carrara ran fantastic on 1 gb machine.
Now i don't trust poser programmers if they been working with vue programmers and god No's what crashes and memory leaks p7 pro will have.
I'm looking forward to carrara 6 as so far seems they have made a new version with Lot's bells and whistles that will rock, so will get carrara 6 and even if 64 bit version.
Will give p7 pro a complete miss, and will install on separate partition my XP 64 but ya better hurry if you want XP 32 or  XP 64 as on eBay the prices have shot up.
Gates ain't gonna do like he did with 98 second ed and dump whole lot from warehouses onto market, as he wants people to use vista and has told comp manufacturers to use vista only.
The destruction of most XP stocks at Microsoft has begun so by Xmas will be near impossible to buy XP from eBay unless someone has bough massive stockpile, though people will use the other methods, so if ya after XP ya better get fast from eBay.
I'm lucky have 2 XP Pro and 3 XP Home and 1 Xp 64 and 64 managed buy for £38 a real bargain.
