Do I get to be the first to talk about your 'L' level cash for your CPU? (better performance is had on CPU's with higher L1,L2 and L3 Cache[particularly L1 level]).

Yalib, it sounds like you are just getting started with inventor. May I recommend that you get your foot in the door before you build a high end computer. If your desktop/laptop meets the minimum requirements download inventor and start to play with it. If you notice a lag in commands, menus, and selecting you likely need more RAM then what you have. If you notice items lags/issues with graphics, you likely need a graphics card with a) dedicated memory b) a higher speed processor. Your CPU is not likely an issue. At inventors minimum specs, your L level cache is more an issue then your CPU processing speed(L level is basically where binary commands about to be processed get stored on the CPU).

if you have to by a computer, listen to the good advice on the thread. Let me add get a desktop computer with a motherboard with alot of expansion room. Your computer will be able to last longer, and you can upgrade the insufficient parts easily. These will have 16ish PCI express slots, no on board graphic capabilities, 4 memory slots.
