you have to take in mind that RHT Will make you'r dual core cpu useless for multitasking, and believe it or not but 90% of you are multitasking and do need the dual core mutli threading ability, example is simple (True one from my experience):
I like to go AFK on some game no matter what its called and put a bot (Its legal there, anyway) but sometimes botting is boring--so I'd like to go play BF2, with RHT That turns my two, mutli-threading-able cores into one logical unit won't allow me to, but if I don't use RHT, I can set up the other game to only use core 1, while BF2 will run on the 2'nd core, thus I will not lose performance at all in either of the games.
So yeah, games doesn't do mutli threading yet, but we still need that in most of the times
, another example is when you'r copying or burning a DVD, it takes soooooooooooooo long and you can get soooo bored....... you get my point
just my 2 cent...
