Help me to choose a laptop

[themaskofwraith]

i have finalized my laptop selection to these models. But i have hard time deciding which one to pick.

Among these i prefer Qosmio one, as it has features which are absent in others like,Blue ray writer, 12 cell battery, 2 HDD slots, e-sata. and i think its more gaming grade than others.
The only thing which im concerned abt is Gtx 460M, while other model sports 750M and 8850M. How grpahics performance im loosing by choosing this laptop?

Thanks in advance

Of the three I would go with the Lenovo Ideapad Y510. The qosmio is about 2 years old 2nd gen i7 and an ageing 460m, your kind of already putting yourself behind the 8-ball on that one.

Regarding the CPU
Y510's 4700MQ is better than 2630QM, when single core is active.
" When more than one core is tasked or the GPU is stressed, the clock speed drops to only 2.4 GHz" from the y510p's review.
While the Qosmio's 2630QM still maintains 2.6Ghz with all four cores engaged.
Im really not sure if there is going to be any CPU performance change.

And the Y510's battery is rated 65W while power supply is 130W, so on the battery the performance of the GPU will go down atleast 40% . And GTX 750M has 128 bit memory bandwidge, while 460M has 192-bit bandwidth.
