I cannot see a home desktop PC (gaming rig or not) benefiting from anything over 1 Gig. You might be able to justify 1.5 Gb, but there would have to be some sort of control (i.e a benchmark(s) ) used for a comparison between 512 MB, 1Gig and 1.5 GB to see any difference.
If anything, more RAM can make things run slower. As posted above, there is a point of diminished return. A desktop PC with the current XP 32 bit OS (and Games or other programs) can only use so much RAM for it's resources. On an AMD 761 Chipset MB, I had 512 MB ram, I added an extra stick of 512 (both cas 2-2-2 low latency). It 'seemed' faster. But after running several benchmarks, I actually lost some performance in my memory. Not a lot, but I NEVER benched higher than the 512 MB. The MB supported up to 3.5 gig (2 gig non-registered and 3.5 registered – which the manual states is more for a server than for desktop usage).
Increasing the RAM beyond what the components & programs can optimally use does not mean extra performance.
The fact that a computer 'seems' to run smoother is a placebo effect. It's like, you give a group of people pills and say it will take headaches away. You give out to one group medicine (say Aspirin) and the other gets a placebo (i.e. 'sugar pill'). After 2 hours, there will be many (not all) that claim relief from their headache even though all they took was a placebo.
If you want to prove that your system benefits from 2 Gig over 512MB or 1Gig etc.., then run SiSondra, PCMark and or 3dMark etc.. and see if there is an measurable difference between them. But I believe that you will find that there is either no difference or a decrease as you go up. You would actually gain a lot more by improving components (add some WD Raptors and a good video card) and fine tuning the settings in your Bios.
And I'm not putting down, or afraid of 2 gig or 4 gig or 10 Gigs of RAM. The new AMD FX chip is recommended to use 1 GB - of registered RAM - to run properly. And I'm sure that a 64 bit OS will require a bit more ram that our current 32 bit. The key is to use Faster RAM (ex low latency and DDRII when it comes out) over copious amounts of it.
