Two things are needed to make that system gaming ready.
1: More RAM, which you're already working on
2: A better video card
For $50-100CA, you're not going to get much in the way of a video card, but what you can get will probably still be better than what you've got. The important thing however, is to find out if you have any free slots for a new graphics card. Does your system have an AGP or PCI-E slot? Not all name brand systems do. If it doesn't, then you're limited to PCI cards, and you'll need a free PCI slot. Do you have one of those?
Also, be sure to get the best card you can for the money. Don't skip over a card with Pixel Shader 3.0 just because none of the games you have now use it.
And just something I'm going to toss out there since you seem to be on a tight budget: Console gaming. It's FAR more economical to get a console for gaming than it is to continually upgrade your computer. Especially since unless you have a custom build system, and you or the person who put it together was very careful in their selection of parts, you're going to hit a wall on your upgrade possibilities very quickly.
Consoles are great, because you buy the one console, and all the games with that console's logo on it are guaranteed to work. There's no need to upgrade your hardware more than once every couple of years when the next version of the console comes out. So when you look at it from that perspective, even the high initial price of the 360 and PS3 aren't so bad. You have to consider that the cost is being spread out over probably 3-5 years at least. Plus, when you figure how much money you sink into new hardware just to keep up with games, it gets to be even more reasonable.
Then there's also the freedom from all the DRM and copy protection garbage that has invaded PC gaming. Whatever company it is that's behind Bioshock is a classic example. You can only install the game a maximum of 5 times. So, even if you format your system because of a virus or a your hard drive goes titsup, if you've already installed it 5 times you're going to have to call the company and hope they will give you another chance. This sort of thing is only going to get worse as time goes on. Consoles help free you from this.
So my advice, would be to give a good long hard look at something like the Sony PlayStation 2. It's a bit older, but it has a massive game library, and there are still new titles being developed for it. Just not as many as a few years ago. Still, you can go to places that sell used games and experience dozens of great games for very little money. Save the money you were going to sink on new hardware and put it towards either a 360 or PS3 a year or two from now when the prices have come down a bit more.
