Intel is supposed to release new CPUs in the next couple of weeks and figure a couple of weeks for the reviews and price shake out on older stuff. Gestimate 6 weeks or so although just read Intel is delaying the release of their high end CPU so who knows. In a year of so there will be new chipset requiring a new mobo so the current 775 is at the end of it's cycle but the current board P35 will run the Penryn, Intes newe 45mm CPU. I would guess close to 18 months or so before the new mobos and CPUs will have a price drop, could be less. Doing rendering you'll definitely benefit from quad core. Right now the 8800GT seems to be the card of choice for gaming but again both nVidia and ATI are coming out with new GPUs but not being a gamer someone can better comment. As for waiting, if you don't need something immediate, would be worth waiting a couple of weeks to see if there are anymore release delays. If there are, I would buy now. Good mobo would be a Gigabyte P35 DS3L or ASUS P5K E with or without WIFE depending on the feature you want.
