GNOME performance hit on 486?

["AU,SCOTT CHUONG" <sau@ucla.edu>]

I've been itching to install Gnome both for the utilites as well the
greater desktop control.  I'm worried about the performance hit my box
will take though with the increased graphical desktop (as compared to the 
simpler nature of IceWM). Anybody running a similar processor (I realize
people running 700 Mhz Athlons aren't going to notice any difference) have
any input to this matter?  The 486 has 32M RAM and runs Netscape
incredibly well compared to Windows 98 (which doesn't run at all on this
system).

Thanks in advance,
