Hey guys, I'm looking to upgrade my ram to 4gb here is what I have now: Newegg.com - CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit Desktop Memory - Desktop Memory
As you can see, it is an old DDR400 and my motherboard isn't exactly new either (socket 939). I was wondering, do I absolutely have to buy the exact same memory to get the full potential of 4gb? Because my mobo is so old, these dated memory sticks are really pricey.
And this is probably a retarded question since I've been away from the computer tech scene for so long, but what exactly in layman's terms is RAM good for during gaming? Will it give me an FPS boost? Will games load up faster? I play mostly RPGs with big open worlds, as well as fast-paced FPS games like Team Fortress 2 and Left 4 Dead.
