Very good point, I didn't think of that. I'm looking at M58 specs, and it uses a Intel Q45 Chipset, which supports PCIe 2.0. (I'm running a 3.0 card in later PCIe 2.0 system myself, no problem.)
All those Nvidia cards are PCIe 2.0. And according to Wiki: "Overall, graphic cards or motherboards designed for v2.0 will work with the other being v1.1 or v1.0a." If you can determine definitively that your PCIe is 1.1 or 1.0a, you've got a good change of it working. If it's 1.0, I wouldn't chance it.

Update: You're in luck, your Chipset support PCIe v1.1. Intel ® G41 Express Chipset and the newest card that will work is a v2.0.
My reading of the Wiki v2.1 section, suggests that v2.1 and later cards may not work in a v1.x slot.
