Hi all,

I have been running several MSI GTX 260s factory OC for several years. They are champs. They easily outperform 2 ASUS 450-series cards I have. I would like to upgrade for performance and less power consumption.

I really like the looks of MSI's GTX 660 factory OC 2 GB card with 960 CUDA cores for about $200. Going to a 680 is well over double the cost. Even 670s are almost double the cost.

What are your thoughts? The card is PCI Express 3.0, which will work in my PCI Express 2.0 slots as I understand it. How many WUs can I expect to run on such a card simultaneously?

Thanks.

I normally run 2 at a time on my card, but can easily go to 3 if I want too.

I leave it at 2 as this is also my primary system.

Shorties are coming in around 3 minutes on the 660 while the 670 does them in about 2:15.

You are getting about double the performance of my 260s. I looked at my latest results. Running one WU at a time, the last 3 short WUs were 2:51, 2:53 and 2:58.
