1st Laptop, Needing some help

[kiddagoat]

Hello again everyone at Tom's. I have a new question for you all as I am finding a lack of information on the web about an upcoming purchase of mine.

I am looking to buy a laptop for back to school and I would like to know if it would be possible for someone to explain the differences in the following GPUs for me. I am looking to get a laptop with some decent gaming performance and also still provide good portability in a laptop.

The contenders are:
ATI 5650m
ATI 5730m
NV 335m
NV 425m

I have been looking all over the net but cannot get any good reviews at all. I could fork over the cash for a laptop with a 5850 or 5870 but those systems seem to be defeating the purpose of a laptop. They are more desktop replacement.

My desktop is as follows:
AMD Phenom II X3 720BE
8GB DDR3 1333MHz
Crossfire 5770s

So a laptop that would be a good supplement to this desktop. The laptop will be mostly used at school and on my travel's to LANs, grandma's, etc.

As far as I know there is no mobile 400m GPU other than the GTX480m.Among the 5730 and GT335m, both will have similar performance, but the 5650 will have slightly less performance than both of them.

As far as I know (which is only a few..lol), mobility GPUs are usually "weaker" than its desktop twins (same first 2 series number)

Since you have a crossfired 2xHD5770 setup, the closest one is the one you don't want to have since it will defeat a purpose of a laptop, the 58xx series.

The best compromise is to have an ATI HD5730m, the reasons are simple: you already predetermined the nominees and qualifications, phasing out the 58xx. you're also familiar with ATI's products on your desktop. So, as a 1st laptop, accustoming would be a stroll in the park. You'll know better than anyone not to expect a laptop to match up your crossfired desktop PC's muscle power. It should run current games pretty well though, especially the ones dubbed "gaming notebooks".

Hope this helps!

Hello
5730M> 5650M> 335M> 425M
So the best choice is 5730M and it will perform like a desktop HD 4650(a little slower)
