I'm sure there are lots of Mac proponents that will swear up an' down that Macs are the dope, but I've never listened to these people.... :)~ If you're going the PC route, get the fastest processor you can afford, the AMD 2000+ quanti might be a good bet, plus you'll get the added bonus of being able to use DDR RAM. yeah, I know the new P4 chipsets allow for DDR, but there's an old addage in the PC biz... Never be a pioneer. First generation Intel chipsets have been notorious for being problematic. You're gonna want DDR Ram and 2 (or 3) large harddives, 60 gigs or bigger, for swapfiles and virtual memory. Don't worry too much about your graphics card as Poser 4 has no 3D acceleration, but you should be able to get a dandy GeForce2 64MB for under 100. if you got more money go for the GeForce3 Do yourself a favor and insist on XP Professional as your OS. i have virtaully NO problems whatsoever. Poser NEVER locks up and I run Poser, DeepPaint3D, Photoshop, Winamp, and Burn CDs and surf (all at the same time) while I render with No worries.
