but running 6650m alone ady better than gt540m right? can it run on dedicated card onli?
By specs, 6650 should be faster than 5650.
Look at the benchmark results posted in earlier page,
http://forum.lowyat.net/topic/1949954/+248http://forum.lowyat.net/topic/1949954/+257My 5650 has the benchmark score 7500+ in 3DMark06 and 1650+ in FFXIV.
GT540 is better than 5650.
But the 6650 doesn't seem running faster than 5650.
It could be non-optimized driver. Another possibility is, you will probably need 1600MHz ram module in order to have a better performance.
Perhaps the Llano users can test the system by using 1600MHz ram modules.
Another concern and old debate, cross-fire/SLI VS single card setup.
If both deliver the almost similar performance, you should go for single card setup.
You'll have less compatibility issue 'cos some games don't support dual-card setup.
So, until there is a better driver, GT540 is a better option for now.
