Depending on use, today I find that 8 to 16GB is sufficient and will NOT, will NEVER speed up a PC much.
As to checking out max, I use Crucial.com a lot.
I asked two certified geeks about my Dell 9020 desktop (no "M" or other model), 1TB SSD, 64bit, Windows 7 PRO, i7, about how much RAM I can use and I got two different answers. One said 16GB max and the other said 32GB max. Which is correct, if either, or is it somewhere higher?
