Laptop video card help

Hi all,

I'm looking at purchasing a new laptop. I'm on a budget, and just looking to do a bit of gaming. I'm not too concerned about being able to run games at the highest settings, just as long as they run smoothly. I've narrowed my search down to 4 different ones, here are basic specs:
CPU: Intel i7-3630 or 3632.

RAM: All are between 6-8 GB of DDR3. If they come with 6GB, I plan on upgrading to 8 at some point. All have a max capacity of 8.

The video cards are where I'm stuck, and I'm wondering if the difference between these four is enough to make my decision. Here are the four video cards I'm looking at... each laptop has a different card. All are NVIDIA GeForce: 630M, 640M, and 730M (one has the 2GB version and one has the 4 GB version).

Are these video cards different enough to make a big deal out of this decision? From the benchmark sites I've been searching, the 640M looks better than the 630M, but I'm having trouble finding much about the 730M.

Thanks for the help!

Here are the four links to the laptops for anyone who's curious:

Newegg.com - Acer Aspire V3-771G-9441 Notebook Intel Core i7 3630QM(2.40GHz) 17.3" 8GB Memory 1TB HDD 5400rpm DVD Super Multi NVIDIA GeForce GT 730M

The 640 is quite a bit better than the 630, and I believe the 730 is a rebranded 640, but I may be wrong about that. I'd go with the latter two over the 630.

 

730m is an 640m with higher clocks so just go with that, 630m is quite slower than both cards.

 

I hate to be that guy, but you can do better for that price range:

Sager NP6350 / Clevo W350ETQ - XOTIC PC - 15.6" Custom Gaming Laptop

Sager NP6165 / Clevo W150ER - XOTIC PC - Sager 15.6" Laptop

FORCE QAL51-FHD / Compal QAL51 - XOTIC PC

FORCE 16GA-005 / MSI 16GA - XOTIC PC 15.6" Custom Gaming Notebook

XOTIC PC | MSI GE60 0NC-498US

Of course I don't mean to advertise XoticPc, there are many other resellers like mythologic, powernotebooks, lpcdigital, etc, but these are all good models in my opinion for your budget.

 

Thanks for the help, guys. I did check out the XoticPc site, but as soon as any upgrades are added to make a system comparable (and adding an OS), the price shot over a grand pretty quick. I ended up going with the i7-3630 Acer with the 730M.
