all hackintoshes are more work, more risk then a macpro, that's what you get for the money you save, if you don't have the patience or the willing to plan ahead for problems then you should save your money for a macpro.
that said, your problem with the gtx460 is your fault, this card (and all fermi) has been known to cause issues with hackintosh since they came out last year. i have a gts450 and lived with snow leopard issues all that time until lion came out. If i had bought a radeon 5770 last year i would have had no issues all this time.
there are always risks that what you buy now will not work later when you do this. but remember you don't always have to update. i have a netbook running snowleopard 10.6.2 and another laptop still on leopard, of course there are things i cannot use, but both are still useable day-to-day. and even if you plan on updating, you always have to do it the right way, meaning you have to create bootable backups and always be ready to restore.
you have to decide what is more important to you, the money to buy a real apple or the time/hassle of dealing with a hackintosh. for those of us that enjoy the tinkering, we use hackintosh
