If I upgrade my T7250 intel processor to the T9500 would I be able to play current games?
I have a Dell Latitude D630 with 2 Gbs of RAM which I am upgrading to 4, and I'm using an external graphics card. My current processor runs 2.00 Ghz I have been told I need more to play current games such as Assassin's creed 3
Older laptops tend to have an ExpressCard slot, and there were external GPU enclosures made for that interface. Problem is they are at best the equivalent of PCI-E x1 version 1, so they will starve most decent graphics cards for bandwidth.
Short answer, buy a new laptop or build a desktop if you want to game, you're not doing it on that laptop.
