Buy an OEM version of Amazon its a lot cheaper, i saved £200 and it installed without any problem. The only thing the oem lacks is ms support and you can only copy to 1 pc motherboard. I only need it for my gaming rig so its fine for me.

Here is my setup.

Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz (2 CPUs), ~2.4GHz
4 Gigs DDR2-SDRAM PC2-5300
NVIDIA GeForce 7900 GS x2 Dual (upgrading)
AGEIA PhysX 100 Series PCI Card
Creative SB Audigy 2 ZS (X-FI removed after vista install)
NVIDIA RAID Stripe 500 Gig (Dual HDD config)
Creative Inspire T7900 7:1 Speaker system.
Logitech G15 (Blue) Gamers keyboard.
Logitech MX518 Gamers Mouse.
Saitek Cyborg Evo.
Vista Home Premium SP1 x64
