Video Card Help?

Well right now I'm running a Nvidea Geforce Fx5500. Yea its pretty old. Anyways im wanting to play a few games such as Left 4 dead on my pc and ect some newer games even Left 4 dead 2 if i get a decent video card.

Atm I only have 1.2G of ram, Which I will be upgrading that soon.

Right now my system specs are:

Operating System:
Windows XP (32 bit)

Video Card:
Driver: NVIDIA GeForce FX 5500 256 MB


Memory:
RAM: 1278 Mb

I believe my processor idk never knew much about one, it sais Pentium 4 CPU Intel 2.80 Ghz.

Anyways Im looking for a vid card like i said, I would be purchasing it on new egg but not right now will be later on, Just wandering what would be a decent video card I could purchase, Not serial but IDE.

Im looking into Nvidia Gforce 7000 or So, I Believe my budget would be around $40-50 would anybody be interested in showing what would be a good video card for my budget?

I know I will be upgrading my ram soon, But as for processor Idk anything about. so any help on that would be great.


Also was looking how do I find out if I have DDR2 or whatnot? Can I change from DDR2 to 3? Im not familiar with this.

 

You most likely are using DDR RAM, not DDR2. To change it, you would have to buy new sticks of RAM and buy a new compatible motherboard. Only upgrading your GPU isn't going to help you much if you don't upgrade the rest of your parts, which are to say in the least, outdated.
