Don't listen to Zackin, hes stupid. If he doesn't know correct info, he shouldn't post. A graphics card would help, but RAM is a much cheaper solution to higher FPS (in Minecraft at least). I used to have 1GB of RAM and integrated graphics, but I recently bought an extra 2GB of RAM and now I can run Minecraft at about 35FPS average. The reason of this is because Minecraft doesn't require graphics at all, it will barely help to get a graphics card. You are rendering thousands of blocks as you walk, which can get heavy on your RAM and processor. A better processor would help too.
You're really overacting, How am I supposed to know if my info is correct or not? If I kept it to my self all the time no one would ever have a chance to correct me about it.
RAM isn't exactly the first thing you'd want to upgrade in order to increase FPS, the CPU and GPU are the first things in that regard. But of course if you've only got 1GB of RAM then it really would make a difference if you where to upgrade it.
