We just got a nice shiney Dell Dimension-TW XPS 720 H2C/Intel Quad Core Extreme QX6850 3.0 GHz/4096mb Ram/1.2TB (4x 320gb RAID)/COMBO Drive/DVD-RW Drive/SoundBlaster X-Fi Xtreme Gamer/128mb AGEIA PhysX Card/2 x 768mb GeForce 8800GTX's SLI... for video editting and the like,

Just wondered how many of you (if any) have a beast dedicated to this sort of thing?

Not bad for £700 :-)
