For numerous reasons, No.
Why is explained in this MSDN post.
First, from a performance perspective the pointers get larger, so data
structures get larger, and the processor cache stays the same size.
That basically results in a raw speed hit (your mileage may vary). So
you start in a hole and you have to dig yourself out of that hole by
using the extra memory above 4G to your advantage. In Visual Studio
this can happen in some large solutions but I think a preferable thing
to do is to just use less memory in the first place. Many of VS’s
algorithms are amenable to this. Here’s an old article that discusses
the performance issues at some length:

porting Visual Studio to 64 bit is to port most of it to managed code
incrementally and then port the rest. The cost of a full port of that
much native code is going to be quite high and of course all known
extensions would break and we’d basically have to create a 64 bit
ecosystem pretty much like you do for drivers. Ouch.
