I recently got a new display (Samsung SyncMaster P2250) and the PC I'm using it on has a pretty outdated hardware configuration, making my main problem the graphics card. The PC is a Compaq Presario SR1010Z.
CPU: 1.80 GHz AMD Sempron
RAM: 512MB (upgrading to 1GB/2GB soon)
MOBO: ASUSTek Computer INC. Salmon 1.04
Graphics: SiS 760 (Display adapter)
What I need is a new graphics card that can output FullHD 1080p (1920x1080) resolution, and I also need to know whether my current configuration can even support a graphics card like that. If so, I need to find a low-budget card that will perform nicely, hopefully something that'll be able to play 720p/1080p video (but not necessarily).
If not, what needs changing in order to get a matching graphics card to work in the system?
