Rate this computer's specs (I'm planning on buying soon)

[JOKA_]

HP Pavilion

• Intel(R) Core(TM) i7-960 quad-core [3.2GHz, 1MB L2 + 8MB shared L3 cache]
• 12GB DDR3-1333MHz SDRAM [4 DIMMs]
• 1.5TB 7200 rpm SATA 3Gb/s hard drive
• 3GB DDR3 NVIDIA GeForce GT 440 [DVI, HDMI, VGA]

 

I'm not really looking to game on it, but I am looking to create 3D content and this comes in at around $1000

I do have a question about the power supply though, i chose 460W but there is also a choice for 600W.  The site told me it will inform me if I need the higher power supply, but it didn't so I assume I'm ok...?  I really have no clue what this means.

 

Thanks for any thoughts!
