Is it any faster or better than the 32bit version?
No. But it's worth using 64-bit apps on a 64-bit OS if you have a 64-bit computer, just because that's the direction everything's moving in.
I thought 64bit apps were supposed to be really fast but it doesn't seem to make any difference.
64-bits is good if you need more than 4GB of memory, or if you have a 64-bit app that does a lot of 64-bit number crunching (like a video encoder). A web browser doesn't need that much memory and it doesn't do a lot of math.
Oh ok...so it looks like 64bit apps wont be having much of an effect on mainstream programs then.
you got it.
On x86_64 you get another 8 GP registers and an additional 8 SSE registers as well. Based on some tests I did with q3map2, the quake3 map compiler, I gained about a 25% increase in speed (it does not use SSE). Most 64 bit compiled media encoders I tried gain quite a boost as well. With something like firefox you might notice minor speed increases on client-heavy pages, but that's about it..
I'll let wiki do the rest
