That link works, thanks - Emptying my wallet of £100 as I type...
...as for boot times, my gaming PC has 2 average performing M4 SSD's in RAID 0. Cocked up there because TRIM can't/won't run on RAID. I will be removing the array and using both disks separately once I get W8 on there.
I don't think the MBP will care too much, performance wise. It will always be held back by Boot Camp compared to if it was natively installed on this (pretty fast) hardware. Either way, I will know within the next hour or 2 - It's downloading the image so I can burn it to DVD.
Thanks again for helping find that link.
