i agree, u will definantly need more ram...i suggest at least 512MB. its really cheap nowadays anyway so thats no biggy. also get a graphics card, like a GeForce3 Ti300 or a Ti500 if u got the cash for it. hard-drive space is a matter of opinion, high quality scans for photoshop alone can take like 100-250mb each, then the edited document another 100mb or so. poser saved files usually are around 50mb each and so on....i'd suggest a 40gig or so. other than that u should be pretty set with what u picked out. i am running an Athlon XP 1400+, 512MB 266mhz DDR Ram, GeForce 2 GTS (i know, i gotta upgrade) and an 80gig Ultra-DMA133, 7200rpm HD (never came even close to filling it). and i am using the same programs u meantioned above and everything renders pretty smoothly on my machine, even volumetric worlds in bryce i can render in less than 3hours.
