Your machine sounds more than adequate, except for (as you've guessed)
the video card is starting to get a bit dated.
On Linux, you don't want to use anything but nvidia still,
unfortunately. I'd recommend picking up a GTX 280. I develop using
that card daily and it's more than adequate. Google reports that you
can pick one up for a hundred bucks.
Of course, you can spend more and get better results, but I would be
very surprised if you didn't get interactive performance out of that card.

Avoid intel everywhere. Avoid ATI on Linux.
