Looking to build a comp. need help

[tw23]

So, I'm planning on building a computer.
And I'm on a budget.

I want to know which one would be better for gaming...

an i5 2500k + Radeon HD 6850
or
an i7 w/ Intel HD 3000 Graphics

They are about the same cost, and I need some help choosing.
Which one in your opinion?

the first one by a huge margin. like its not even close.

also you'd better off with a 2400 with a 6950

or a i3 with a 6970 would also be even better.
