Is 4gb memory really worth it?

As title. I'm contemplating getting some 8500 speed memory but theres mainly only 2 x 1gb kits available other than the 2 x 2gb offered by ocz and gskill. I'm currently using 2 x 2gb ocz 6400 (as in me sig), but when me wolfie 8400 arrives I'm hoping to be able to push the fsb above 400mhz which I reckon is gonna put a strain on the memory.
I don't do any heavy image manipulation like photoshop, etc and just normal gaming. Me question is would I really notice a difference in general performance if I go from 2 x 2gb to 2 x 1gb? I don't recall any difference noticed in the past when I changed over from 2gb to 4gb but I'd like to confirm that first.
Wadya reckon?

You'll not notice any difference by using faster ram. But it could restrict the overclock of the 8400 slightly. Running at 1:1 you be overclocking the ram speed. So you may need to increase the voltages or loosen the timings slightly, or both to get a stable system.

I would say it wasn't worth getting 8500 memory, as the performance difference would be minimum, even if the 6400 did restrict the cpu overclock.

But faster ram would allow me to overclock the wolfdale well past 400mhz fsb, whereas with the 6400 ram, Id be limited to around 400mhz max. And faster ram would aid not restrict the overclock, thats whole point of faster memory. I think you misunderstood what I was asking, basically, would I notice a difference going from 4 gb of memory to 2gb

Forgot to mention, this is on a dual boot system, XP 32bit and vista home premium 32 bit. See, there wouldn't be a prob if I was 100% sure me memory is gonna overclock to about 450mhz (900 ddr) and if it doesn't and assuming the new cpu will do 450mhz fsb, then I'm gonna have to get faster ram, 6400 to 8500. Now theres only a few sets of this 8500 that you can get in 2 x 2gb, all the others are 2 x 1gb.
So the question is, assuming I have to get 8500 to allow me to overclock to around 450mhz, would I notice the difference between 2gb and 4gb used in both the 32bit operating systems.
Shoulda mentioned that I reckon, my mistake.
