hi, im getting a new system tommorow, asus k8ne dlx motherboard, amd 64 3000 processor, 1gb kingston ddr 400 ram, etc. i was wondering, will the bundled heatsink and fan of the processor be enough? coz i mainly use my system for 3ds max rendering and games, so will it be able to take the heat with the bundled heatsink or should i go in for another one? also, is a 300w power supply good enough or i need a more powerful one?
