@magicalclick: In theory GPT should allow you to multi-boot operating systems without a third party boot menu/system. In practice Microsoft is working very hard to screw that up.
Other than that GPT is really about >2.2 TB storage and making it easier to write disk management utilities. There are a few more theoretical benefits like a larger number of partitions but most systems, even enterprise systems, won't ever see those benefits.
Keep in mind that once an Operating System is running neither GPT nor MBR is ever really used - so you'd never expect to see true performance increases beyond 1~2ms at boot.
well there is one other thing: gpt allows more partitions on a drive than mbr.
but how many folks need / want to parttion a drive into more than 4 anyway ???
for some stuff like multi boot and linux it might be great but for just plain old windows installs the number of partitions is almost a non issue.
