Hi I am planning to buy a laptop here are the few I shortlisted can you guys tell me which Is the way to go
This is the dell with 8850 ddr5 but comparatively I see it 4500u is not great

This lenovo is almost final only thing making me think is the ddr3 740m will it be future proof? Also If it's 64 bit or 128 I m not sure
But it 4207mq is great also I get a 8gb ssd in a very nice price the spot

Here i5 4200m is good but again 740m for such a price difference

Finally this, a little over my budget but then again it 4200m will be good I think and it has 740m n14p gt1 I think it's the slides version with ddr5 also with the lenovo ultrabay so is it worth all the money?
