I am currently running 10.4.6 Tiger on my Intel box and was wanting to upgrade to Leopard, but needed some advice as to weather I should do all of the updates for Tiger first or can I just simply upgrade from this point? The system is running flawlessly other than the usual problems with video driver support. I haven't had any major problems since my first install and would like to avoid any if all possible. I can't get any of the latest software updates to work until I update the OS to the latest version, so I guess that would be my first step.
I need to know from anyone who is currently running Leopard, is there any real advantage to updating to Leopard from Tiger or was it a major hassle?
First off I am going to update to the latest version of Tiger (10.4.11) before I decide to go any further.

Thanks in advance!

One thing I did notice in the system profile is that my processor is posting as a dual core 3.6 GHz? The correct posting should be 3.2GHz single core (I do have the CPU overclocked by 5%).

Machine Name: Apple Development Platform
Machine Model: ADP2,1
CPU Type: Intel® Pentium® 4 CPU
Number Of CPUs: 2
CPU Speed: 3.6 GHz
L2 Cache (per CPU): 512 KB
CPU Features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM EST
Memory: 3.0 GB
Bus Speed: 560 MHz
Boot ROM Version: 1009.003 (American Megatrends Inc.)

Something else that seemed strange is this:

Firmware Revision: B028
Interconnect: ATAPI
Burn Support: Yes (Unsupported)
Profile Path: None
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No

Now seems to me this is conflicting information...is my DVDRW compatible or not? Will burn support be supported or unsupported?? I haven't tried to burn anything yet, because I am still waiting to see if I can get full support for my video card..still working on that issue.

This is quite odd, but I am sure it is fixable. Any ideas?
