I'm upgrading memory to try to get my games to go faster (Medal of Honor:AA, Jedi Knight 2). Right now my computer has 128MB of SDram. I have $55, which is enough to buy 512MB from PNY or Kingston, or 256MB from Crucial. My friend says that I should only buy Crucial brand because it is the best. And after all, it is advertised on this webstite But maxing out on memory seems like a good idea. ANYWAY which of the two upgrades would give me better performance?
