I had a 460+650ti in a system and once I got it set up right (both monitors had to be on one card) it worked just fine...
The only thing I can suggest is I would try a clean driver re-install.

I was using the older drivers for folding@home performance... Guess now I'm running here again I can update.
I always leave cpu core open for GPU... Also set GPUgrid to use that open core fully for better performance.
The 700 series gpu's are much better performance than the 600 series so I'm not overly surprised. The 650 and 750 also have a 128bit memory bus so it could be that slowing things down as well if its a big protein.

I was running short units in 3 hours with the CMYBKIX tasks on my 650Ti so I thought I must be able to run the long units in under 24 hours... boy was I wrong! 35 hours in and only 79% finished. Whoops guess I learnt my lesson!
Back to short I go :)

Sorry I thought I had replied but it appears as though I didn't.

Thanks for the answers,

There would be a lot of connections but each connection would be a small amount of data. Its the same amount of data overall from what it sounds like... just sent over multiple connections. I'm not sure what the net result for server load would be though.

I see over at folding@home they are testing a new core that is a streaming core (it sends data to the server every frame instead of once per wu)

I was curious if gpugrid was looking at doing a similar thing? It sounds like it has multiple advantages - all usable GPU's can be used without worrying about it being too slow (since data gets returned much quicker), don't need to worry about waiting for wu's to timeout if lost/person quit, no deadlines to worry about for slower GPU's.... There may be many more but those are the ones I know about.

I'm having the same issue... Was this ever fixed?

Judging by this line here:
28/03/2010 17:55:04 Resuming network activity

It appears as if network activity was suspended.
That would be the source of the trouble.

Not true. He is trying to sell you more than you need.
Its more likely that your CPU will be the bottleneck for high end games (once you get new vid cards)

In GPU grid the memory doesn't increase performance much at all... Maybe 5% increase in speed if that.

Lowering the memory clocks does reduce power usage. How else would the power saving 2D clocks work if it didn't use less power at lower clock rates?

The biggest changing factor in performance will always be the number of shaders and their speed followed by the core speed.
