Yeah... The 6xxx series aren't that expensive.
But as I said earlier, the only real problem is my motherboard.
It's this model:

and I don't know, but it's probably going to have some compatibility
issues with newer cards, as a lot of them are AGP 8x, etc...
5600 is also an 8X card.
Your board has AGP Universal slot, it will run a modern 6xxx
or 7xxx AGP card.
I'm running of a 300W power supply, 1gb ram and a 2.53ghz porcessor.
If there's a particular card that someone can recommend in my situation
it'd be greatly appreciated.
The PSU could be a limitation, you'd be wanting to avoid mid
to higher end gaming cards. Some 300W PSU are MUCH better
than others too, if you definitely want to avoid upgrading
PSU then post your PSU make, model, 5V and 12V amperage
ratings.
Also you wrote "low-budget" card but that could be
interpreted differently by differnent people. It'd help to
have a price range and a rough guesstimation of how long you
expected to keep using the system.
Of your prior tasks descriptions, the newer games are the
only thing that'll get the most benefit out of spending
more, but clearly will do that. A typical generic answer is
a Geforce 6600GT as they've dropped down under $130 after
rebates, maybe even sale prices recently. That could be too
much for your power supply though, especially if you have a
lot of hard drives or the supply doesn't have a lot of 12V
amps. There are VGA charts at

Which should give you a rough idea, keeping in mind you'd
probably want at least an average framerate of 50 or higher
to cover the times when frames drop to lowest levels. These
days reviewers also tend to enable much if not all eyecandy,
so if you can do without some of that or don't run games at
high resolutions, you can get a little more performance than
implied on some of the listed cards, especially the lower
end and older models.
