I7 sandy bridge, 2gb nvidia graphics but low ghz

[jayjaybee]

Hello,
I'm thinking about buying a lenovo y470. It has the i7 sandy bridge 4gb upgradeable ram and 2gb graphics. thing is the ghz is only 2.00. I'm confused, right now i have an acer 4740g with the old i5 processor and it has 2.26 ghz. I really want to get the lenovo- can someone explain if the ghz matters that much. I've looke at other with an i5 or even i3 that has more than that!
cheers for your help
jay

of course it matters, but cpu architecture and physical core count matters more.
if you want good fps in games, the gpu matters the most, video ram is only good if your gpu is fast enough and if you are running at high resolutions.
