Finding the right Studio Laptop

Hey,

So I've been looking around Dell's website and I'm getting pretty confused. It seems depending on how you click around Dells site you can find so many different versions of the same laptop! For example for the Studio 15 you can find it with pentium, core 2, i3, i5, i7 etc.

This makes it really hard to decide what is the best deal or to even see all of the deals. I've found different versions of the studios on these pages.

with core i7 http://www.dell.com/us/en/home/performance-deals/fs.aspx?refid=performance-deals&s=dhs&cs=19

with core i3/i5 http://www.dell.com/us/en/home/laptops_great_deals/fs.aspx?refid=laptops_great_deals&s=dhs&cs=19

with pentium/core 2/i3/i5 http://www.dell.com/us/en/home/notebooks/laptop-studio-1555/pd.aspx?refid=laptop-studio-1555&s=dhs&cs=19

And here is another page with a ton more http://www.dell.com/content/products/resultscompare.aspx?c=us&l=en&s=dhs&cs=19&~oe=true&prods=us~en~29~laptop-inspiron-10v_anav1~~,us~en~29~laptop-inspiron-10_anav_1~~,us~en~29~laptop-inspiron-1545_anav_1~~,us~en~29~inspiron-11z_anav_1~~,us~en~29~laptop-inspiron-14_anav_1~~,us~en~29~inspiron-14z-anav1~~,us~en~29~inspiron-15z-anav1~~,us~en~29~laptop-inspiron-13_anav1~~,us~en~29~laptop-inspiron-17_anav_1~~,us~en~29~laptop-studio-new-15_anav1~~,us~en~29~laptop-studio-14z_anav_1~~,us~en~29~laptop_studio_17_anav1~~,us~en~29~laptop-studio-xps-13_anav_1~~,us~en~29~laptop_studio_xps16_anav_1~~,us~en~29~adamo_onyx_13_anav1~~,us~en~29~laptop-alienware-m17x_anav_1~~,us~en~29~laptop-studio-xps-13_anav_1~~,us~en~29~laptop_studio_xps16_anav_1~~,us~en~29~laptop_studio_xps16_anav_1~~,us~en~29~adamo_onyx_13_anav1~~,us~en~29~laptop_studio_xps16_anav_1~~,us~en~29~adamo_onyx_13_anav1~~,us~en~29~laptop-alienware-m17x_anav_1~~&~ck=mn

And thats not to mention the coupon links that you can find through other websites etc.

Ok so to get to my point, I find this entire layout quite confusing! How can one even figure out whats the best deal?

Is there a page I'm missing that has this all a lot more organized, or is Dell just doing this for kicks? Anyone know of a 3rd party website that has this all nicely organized? Anyone have any suggestions at all?

And is there any way to know which version these all are, 1557 etc etc?
