Highest performance score you've seen?
I quite honestly wouldn't upgrade system components based solely on the Performance Rating tool unless of course one was getting 1 scores for anything and not even then, if the system is running aero and behaving reasonably well without too much of a lag in opening programs or files.
For a long time until just a week or so ago I ran 1024 MB of RAM on my test system and never had an issue with running Vista. Simply adding more RAM to a system that shows that RAM is the weakest link is not going to produce a better RAM rating either. If the systems RAM timings can be improved then that would help, but if the timings can't be improved in the BIOS, then I don't think that any amount of RAM is going to make a difference.
My view is that one should wait until more is known about DirectX10 before one goes out and spends money now on system components if Vista performance in general is acceptable at this stage.
Wow... nice scores there, G. (heh heh.... you gangsta, you!) I can't get my 1 GB of RAM to get any higher than 4.5 in this build. 4.5 may be a predetermined limit for 1 GB of DDR? Been scoring the same on my RAM all day, and I have gone from DDR400 to DDR610. It does go below 4.5 when I leave the timings loose at DDR400, but it won't go above 4.5 no matter what.
My old sig didn't match the new board. Therefore, you get to read this text sig.

See if you can tighten up your RAM timings and reduce the latencies on the X2 4200+ system in DRAM Configuration or similar page in the BIOS. Use CPU-Z to see what they are on the XP 3200 system and set the same or better on the 4200+

Technically speaking the X2 4200+ would be slower overall than a single core 3200+, and whilst the OS (at last !) may play happier with a dual core, from the strict hardware PoV the overall lower clock speed of the 4200+ may be a cause of the discrepancy, because of slower overall CPU to RAM I/O.
This is BTW the first hard evidence I've seen to support my theory that dual core CPUs actually have certain disadvantages (in Vista) compared to the faster single core chips of the same generation.
One should remember that dual core CPU technology was originally invented as a means to gain more clock cycles per CPU for use with Windows XP.
It would seem that (in Vista) this extra CPU activity and lower overall CPU clock speed may each contribute to lowering RAM I/O from the CPU. Not good

The memory timings may explain it; I've "tweaked" some of the BIOS settings in my Athlon XP 3200+ system while I have done nothing with my X2 4200+ system with regards to memory settings............... I've looked at the BIOS in my X2 system and it's pretty daunting right now...............lol I don't wanna screw up the good vibes right now

It's quite possible --- this could in any case be an interesting research project for some hardware/overclocking person or other ** cough ** Hugo ** cough **
