Quite a machine. I agree with Nevermore - for all that, you'll need a bigger power supply. But I might disagree about the video card. For one thing, all the cards you are listing here are a little bit old. You might ask your dealer about acquiring a NVIDIA GeForce FX 5700. It should only cost around $200 USD. It has 128 MB of memory and is extremely stable. Otherwise, the ATI cards are all OK and pretty reliable. Very nice motherboard, by the way!
