If you can cool it, yeah it will work. Before I accidentally broke mine I was using my own M2050 for milkyway (amongst other projects), and am currently using a GTX 460 (same core architecture; Fermi) for milkyway and it does well enough.

A word of warning though, it IS very first generation Fermi and thus will run hot and power hungry. Make sure you have a strong enough PSU and ample airflow to keep it fed and cooled.

Finally, i recommend you set up your client to run multiple workunits on it, it is a powerful card after all.
