HI everyone! Im getting a new alienware this friday and I'm in quite a conundrum. My original configuration that I was going to get was a: 2.7ghz quad core processor, 16gb RAM and a NVIDIA Geforce GTX 675M. However, I am now unsure of what I should buy because I kind of want a better GPU. The other configuration that I could buy is: 2.4ghz quad core processor, 12gb RAM and a NVIDIA Geforce GTX 680M. Is there a noticeable enough difference in the CPU and RAM configurations that i would notice it? Is it worth it to dumb down my cpu/ram for the 680?
