What kind of video card do I have in my computer?

I've tried Everest, PC WIzard, system information, and the device manager but the most specific information I can get is
ATI Radeon HD 4800 Series
512 MB
How can I tell if it's a 4850, 4870, or 4830?

There must be something I'm overlooking.

Who is Participating?
Run GPU-z to verify but judging from the clock speeds I'd bet it's a HD 4870.

Thank you, I'll try that.

To clarify, I'm not asking someone to go through all of the technical data here to compare it to the technical data of the 4850 vs 4870 vs 4830 to figure out which card I have by process of elimination.  I'd just like to know where/how I can view the type of video card installed.  How can I get this information *without* comparing technical data from the manufacturer's website?  Does ATI not offer any kind of identification at all more specific than "4800 series" anywhere on the machine?

The video driver usually will, but its been a few years since I have used an ATI based video card. Have you installed the newest version of the ATI catalyst driver?

There was an update to the driver today, and I haven't installed it yet.  Here's a screen of GPU-z and the device manager driver details.  
Surely somewhere on this computer the card identifies itself.....

is it not printed on the card ?

jamietoner has it - the memory used is GDDR5 - that's only on the 4870 (both 4830 and 4850 use GDDR3)
Unfortunately the hardware GUID is just for the 48xx series so there will always be a bit of detective work for the submodels of a particular chipset.
