help with videos cards and my PC

hello
i own a dell 4600C pc and am looking to update my graphics card and i was wondering , since it has such a small design if there are only certain types of video cards i can get. Does anyone have any input on this?

After finding the motherboard specs, your computer will accept a low-profile AGP 8x card. If you want to do some reading on a forum where another guy was having the dilemma you are, feel free this is where I got my info.

There isn't much selection of low-profile cards...so you may be better off getting a different machine or putting all the guts of your current machine in a larger case. But also note if you do this...you may need to upgrade your power supply, as you only have a 250 watt and that won't run much.
