Is the "HT" technology in the pentium 4's really worth it? It's supposed to help multitasking, which my computer can't handle. I have a celeron at 1.8 with 384 megs of ram, but it just can't handle enough things at once. I think the motherboard socket is 478... should i go with a regular pentium 4, athlon or the HT. What I really want is a media center pc... but those are little pricey, esspecially because I have the optical drives, the hard drives, sound card and memory that I want, I would be buying a lot of extras.
