I say wait 6 months.

Yes you are looking at $1800 for 24G ram, today. Its just going to get lower and lower in price. The A card again is on the Sata buss, which is 3G/Sec compare to 28G/Sec of the I7 system memory.

Well if Wow requires a LOT of tiny packets vs. some a bit larger packets then access time will be more important then transfer rate. Would be nice to actually know the number and size of files it needs to access during gameplay, and if they are stored sequentially.

I think it is safe to assume that zone textures would be stored all together not needed multiple accesses ... Why would orgainize the textures in anything else but a zone by zone sequence?

No doubt SSD will be more cost effective. But most threads I am posting in assuming unlimited funds not "best bang for buck".

You spend $400 on the Drive and then $400 or so on 32G ram, so you are almost at 1/2 the price of the onboard ram already. You have 8 slots so you have to get 16G (pushing it) or 32G ...

I don't consider the "hassel" of writing the wow folder to a ram drive and back again as any consequence.
