SOLVED buy wow gear Video Card Upgrade

I know this thread has been necro'd a wow items few times but I noticed that the latest answer was yesterday so I thought I'd ask my question(s) here rather than start a new thread.

I have a Dell Inspiron 530S (yeah I know) so I realize through the threads I've been reading that that will ultimately limit wow gold my upgrades for a video card. My budget is around $150 but I'm not looking to go crazy, just run World of Warcraft better really in a raid setting my FPS can be as low as 5 which is painful. Also my knowledge on computers is pretty limited so hopefully you all take pity on me and ignore my ignorance. What are my best options for graphic card upgrades?

First of all, thank you both for your replies.

Second when I mentioned my ignorance in my first post I really meant it. I like to game but I don't know much about computers themselves. So this video card you linked will definitely be an upgrade to the standard one I have in my 530S and ultimately give me better FPS in a 25 man raid setting (no other items needed)? And when you say brackets I assume you mean the metal strips on the back of the case? Sorry for all the noobish questions but I'd rather ask them all at once then bother you all repeatedly.

Okay wrench97 thank you for all of your input! However I need to pick your brain for a little wow gold longer. In the end I know the 4650 is the better choice for gaming. I know my power supply won't support it forever and I don't want a mess when my computer implodes. So what would you recommend for a new power supply for my slimline? My budget is pretty flexible considering the card(s) mentioned are pretty cheap.

Again sorry for making you do all the work I'm on the site now going through power supplies so I'm not asking you out of laziness, but rather not really knowing what I'm looking at.
