Old Dell Dimension C521 Graphics Upgrade

[Big13055]

Im looking to upgrade from this crappy integrated graphics card.

I have no idea what to get.

All I know is that my PSU is limiting me a lot. (Supposedly is 280-300 watts)

Anywhere I can upgrade my PSU or get a good cheap external one?

Would also like to spend as little as possible.

So If I can get a good card without having to upgrade my PSU due to power insufficiencies, that'd be awesome.

Any ideas?

Current graphics card is Nvidia Geforce 6150 LE

Windows Xp

AMD Athlon 64 X2 Dual Core Processor 4200+, MMX

You could upgrade your PSU but I wouldn't bother as you don't need to to use cards that are appropriate for your processor. This card is a good deal;

and probably about the best you should bother with on a early 2.2ghz dual core. It should allow you to play current games fairly well using reasonable settings at low resolutions.
