Hello: After finishing four long tasks, performance in my GTX295 is really very good in Windows 7-64bits (we'll see in Ubuntu-10.10) about 10 1/2 half hour with overclocking in the GTX295 with MSI-Afterburner ver.2.1.0.

Yields in credits of these tasks is better with normal there a proportion between the two types of tasks and their burden of labour. Best regards.
