In theory it should work:

Core 2 Q9550 @ 3.4 GHz

885*2^846293-1 is not prime. LLR Res64: 46AF89C695A35A07 Time : 594.089 sec.
[2011-04-05 16:33:14 CEST] G9000: 885*2^846293-1 is not prime. Residue 46AF89C695A35A07

llrCUDA 0.6.0 (270.26beta drivers, Linux 64 bit) on a GTX 470 @ 607 MHz:

885*2^846293-1 is not prime. LLR Res64: 46AF89C695A35A07 Time : 593.996 sec.

The problem is: The CUDA app as fast as a core here on and requires nearly a core to do it's work. So the gain is zero at the cost of a significantly higher power consumption.
