650m problems, core clock

Hiya,

I'm having problems with fps in games on my new laptop. Samsung NP550P5C-S02

Intel® Core i7 3610QM
NVIDIA® GeForce® GT 650M
(4 GB x 2) 8 GB DDR3 1 600 MHz

Looks like there are no drivers for 650m on nvidia sites yet. I already downloaded latest driver from Samsung's support.

Skyrim, on max settings: 5-9 / minimum settings:20-30

Of course there are problems in not all, but some other games as well. I'm no expert but this is extremely different than what I've seen on benchmarks.

Could you give some ideas about if this is to be expected, if not what can I do before sending the pc to support, because support is terrible around here.

Thanks in advance.
