ok, so heres a question...

which of these (roughly ish kind of ) equivalent beasts would be better (most stable/speediest)?

in the red corner...

Quad 2.5GHz Intel PowerMac G5, 2GB 533 DDR2 ECC SDRAM, 500GB Serial ATA - 7200rpm, NVIDIA GeForce 7800 GT 256MB SDRAM, AirPort Extreme + Bluetooth, Apple Keyboard & Mighty Mouse, Mac OS X, two 20" flat panel Apple Cinema Displays, One FireWire 800 port, Two FireWire 400 ports, Three USB 2.0 ports

and in the blue corner...

Dual 3.0Ghz Xeon FSB800 2MB Cache, 2GB ECC DDR400 RAM, one 74GB 10,000RPM Primary HD, one 400GB 7,200RPM Video Capture Disc, 256Mb PCI-Express NVidia Quadro FX 3400, Avid Cert 64bit Firewire Card, Standard Keyboard, Optical Mouse, two 19" Formac Gallery 1900 Oxygen Xtreme-3 TFT monitors, Windows XP Pro... (Yes, i've looked at Red Sub )

my guess is the PC - although that is the pricier option...


edit:

actually, may lower the graphics card on the PC - 128Mb PCI-Express NVidia Quadro 1400... makes that package £ 3878.89 (still alot tho!)
