Suggestion new Graphic card

Hi there, can someone please tell me which graphic card will be good for my pc, reason is because I'm getting 25-30 fps in GTA SA (SAMP), and in some maps I get fps drop.

My PC specs:
Game Booster Diagnose Report v1.0 Version: 3.2.0.1417 Date: 2012/01/31 19:00:5 - Pastebin.com

I just want a new graphic card that is able to run on my pc ( requirements).

If this is your motherboard:

Motherboard Specifications, PTGD-LA (Goldfish3) - HP Customer Care (United States - English)

your choices are limited. It has no dedicated graphics card slots, so the best that you could do would be a PCI card. Most cards at this time are PCI-E (PCI-Express), which are entirely incompatible regardless of the similar-sounding name.

What are you using for drivers now? There are no Windows 7 drivers for your onboard (915) graphics. The newest drivers are for XP, and don't support Aero Glass.

Here's a list of some PCI cards available at Newegg (if you're in the US or Canada):

Newegg.com - Computer Hardware, Video Cards & Video Devices, Desktop Graphics / Video Cards, PCI, DirectX 10, DirectX 10.1, DirectX 11, Retail

The cards are usually much more expensive than their PCI-E equivalents. Whether it'd be worthwhile to play a game from 2005, only you can say.

That's my motherboard, between I want a graphic card that is compatible to my pc, I don't just want to throw there a random graphic card that will mess up my pc.

Is that link you put there, can my pc handle it (the graphic card).
