graphics card for hd movie watching on old CPU

[prvprv]

Hi friends
I have a old CPU with MSI 761GM2-V motherboard ( MSI Global ? Mainboard - 761GM2-V )
with AMD Athlon 64 ~2.2 GHz processor and 512 MB DDR RAM

It can play upto 480p videos nicely. but cannot play 720p or 1080p videos.

as it has a PCI EX16 slot can you suggest a ultra low budget gfx card with HDMI output for playing 720p and 1080p videos?

Budget <=2000

Will adding the gfx card improve the performance because it has only 512mb RAM.
Also I cannot add another RAM because the 2nd RAM slot is damaged.

nvidia GT520. It has 3D and HD audio support. Price is around 2.5K. There is one for sale in the forum if you want used one.

if watching HD movies is all what your friend needs just get a GT210 @ ~1.8k and adding the gfx card will improve performance - you no longer have to share system ram to IGP.
