Mendy :
I have a ATI Radeon HD 4200 with apparently 256mb of dedicated ram.
Your video card is integrated into the motherboard. I believe when I was using my integrated card, there was the possibility of
sharing more System RAM and/or
explicitly dedicating a set amount of System RAM(via BIOS).
However, I haven't seen Foxconn or HP's BIOS either ever or for a long time to tell you whether or not it's limiting. Most brand name manufacturer's usually have a watered down BIOS on their boards to keep basic users from messing things up horribly.
I used to think that HP was quality until seeing Foxconn as your board's manufacturer, no offense, haha.
However I have 8Gig of ram on my system, I read somewhere that I if an application exceeds that amount it will borrow from my ram, I'd like to play a game which requires 512mb. Would I be able to play that game?
If you're reading somewhere about RAM, you shouldn't even be thinking of touching anything to do with a video card's RAM. I wouldn't try to even if I knew how, it's integrated on the card or there is a separate bit of integrated RAM strictly for your on-board video card.

On the plus side, you have a PCI Express Slot...
[strike]
The negative side: It seems that it may be a 1.0, so you're gonna have to get a bit older of a card. Couldn't find anything saying otherwise, figured with the specs it'd seem silly to be less than a 2.0.

Not sure if s/he's right, but that's about the only answer I could find.[/strike]
EDIT: Found this posting on this site saying it's a 2.0 which is good news for you, if true.

The other negative: I see this comes stock with a 250W Power Supply, which is probably not gonna give the juice necessary for any good video card. This isn't too bad though as Power Supplies can be very inexpensive.
Just make sure it's at least 400-500W and it should be good for any video card you can put into a PCIe v1 slot.
Make sure that it's
ATX 24-pin with a
4+4 pin or
4 pin connection. Do not get a newer power supply that may just be 8 pin or you're gonna be taking it back as soon as you get it home.
Also, make sure that it
supports at least 2 SATA peripherals (your hard drive and DVD drive), if not you can always buy Molex to SATA adapters. (It's very rare to find anything made in the last 7 or so years without at least 2 SATA connections.)
