D1x vs D40 for low light

[lets_get_digital]

Was wondering which of these would perform better in low light. Have a near-mint D1x w/ 50mm prime and 28-200 tamron lens available to me for $500, which would be about the same price as the D40 + 35mm prime. This will be used almost solely for concert photography which will be posted online (mp doesn't matter, just great low light photos), with the intention of upgrading to a D90/300 whenever the price gets low enough for me to afford. Is the sensor just too old to be worthwhile, or might it be a better pickup than the D40?

Lemme know what yall think! Thanks in advance, you guys have been extremely helpful in the past.

Neither is exceptional in low-light. The D40, being much newer, will be a lot less clunky. How long until you can afford a D90?

EDIT: good suggestion. A D5000 is cheaper than a D90, but has the same sensor with good low-light performance.

The D40 will be much better than the D1x!

Thanks much guys, don't really know specifics about this kind of thing and couldn't find the info anywhere else since the cameras were released so far apart.
