Hi @ all, very nice Community here! I want to buy a newer Computer System. This system is used for Renderings, for example 3ds Max with Mental Ray or Maya! My purpose is to be able to use 3d program and photoshop at the same time. Is this possible? What minimal requirements should have my coming system to work stable, fast and without hardware Errors. The final rendering time is most important for me. Where must I lay my attention? I´m for many tips and opinions happy. Many thanks for help!
