Perhaps we should take a look at the original question again?
>>>Will the extra 256 ever get used if I get the 512?
Not, "Do I need 512mb"
Not, "Do games go heaps faster with 512mb"
Zemus;
Nonsense?
You think you need a dozen programs open to utilize 512mb of ram? I think not.
Im not saying 512 isnt a lot, im saying if you can afford it, and you're not cost-cutting to the point of sacrificing something else to get the extra memory, then why the hell would you not go for 512? I bet Gatesy had a similar frame of mind when he said that no program would ever need more than 640k of memory.
Cosmic;
And again, I agree there will not be a HUGE difference performance-wise in gaming, but even you have to admit there will be a difference.
As far as Anand only using 256mb under Windows XP for testing, I cant answer that, I'm not Anand.
Considering that in benchmarks you try to keep things as even as possible, and some mainboards have trouble when all banks are populated, you remove variables by using a single module. Of course that's only a guess, why not put it to him and see what he says...
