Oracle on NT versus UNIX???

I have an appliction (IFS applications, any experience with that??) running on Oracle 7.3.3 on NT server 4.0 SP3. The hardware is a Compaq Proliant 2500 containing 2 CPU's (Pentium Pro 200) and 1 GB of RAM. With approx. 30 users of the application this server meets the limit. All available memory is consumed by Oracle and the CPU usage hits 100 % in long periods, (end of months etc.). I have two choices:

1. By a new 4 processor NT box.
2. By a suitable Unix box (i.e. Sun Enterprise server 450) and convert the Oracle database.

I've heard that Unix systems are more "CPU-efficient, more efficient code" etc. The ordinary Unix-excuses for being much more expensive... But how big is the difference? Is Oracle that much better on Unix than NT, or could a more powerful NT-box manage the same performance as a Unix-box?

Appreciate any advice on this matter, has anyone done a NT-to-Unix convertion, what was the result, the costs etc.
