I'm about to buy a refurbished laptop because there cheap, i've been using a refurbished gateway for a year no now significant problems i just want better hardware. Now one model is INTEL and one model is AMD. So if anyone wants to look at these two models and give there unbiased opinion that would be cool. M6650 http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4006227&CatId=2289 T1628 http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4010247&CatId=1897 I'm leaning towards the T1628 because from what i can tell the AMD processor has a slightly higher speed. It also has an ATI graphics card with 256mb, the M6650 has integrated graphics with 384mb shared. Am i correct in thnking the ATI would be better over integrated and even though the integrated has more memory its shared memory. Which one of these PC's would be able to generate better graphics. Also i am looking to buy a 2gb DDR2 stick to upgrade to 4gbs of ram instead of 3. I beleive this is the right kind of RAM. http://www.tigerdirect.ca/applications/category/category_slc.asp?CatId=1554&name=DDR2-Memory also what is the difference between the PC numbers ie. PC4200 PC5200 etc does it matter which one i use? Thanks alot.
