so I am choosing between specs.

two laptops same brand and model, DIFFERENT submodel and specs

Been wanting one of these SINCE they were new but the price did not justify me buying one... They came out at last year of vista before 7 (I believe) and have been upgraded to 7 (the quad core one cost $4,200 when it was brand new)

One has an Intel Core 2 Duo T7350 (2GHz) Processor with 6 Gb of ram (max for all submodels) with Nvidia GeForce 9700M GTS dedicated graphics and windows 7 ultimate

The other has an Intel Core 2 Extreme QX9300 (2.53GHz) quad-core processor with 4 Gb of ram with Nvidia GeForce 9400M dedicated graphics and windows 7 ultimate

will be using for normal tasks (internet, word, email Ect.) and light to medium-light gaming (GTA SA, GTA 4 Ect.) plus watching videos/movies

thoughts, suggestions?Do you have links to these machines?  What is the actual model?  How much can you afford for this new machine?

Both of them are pretty old, the second has a much better CPU but the GPU in the first is better, you would need to look at benchmarks to see how the games you are looking at perform on both the 9400M and the 9700M.

Now, as far as the Windows 7 upgrades, and I am purely speculating based on past experience.  Windows 7 Ultimate is an extremely expensive version (At least $200) and provides almost no real benefit over Home Premium or Professional.  Every time I see Ultimate on a SYSTEM it is a pirated copy - I have NEVER yet seen a genuine copy of Ultimate on someone's PC.  For that reason I would be very suspicious of this upgrade as a lot of the time with second hand systems, the previous owner will throw on a pirated copy of Windows 7 assuming that the person who buys it will not notice.  At least ask for the original Windows 7 media and COA with the machine, if the SELLER cannot provide this, walk away or be prepared to either use Vista/pay for a new copy of Windows.
