To give you a good idea of where that i5 stacks up, it is VERY similar in performance to my i3-390M CPU in my 400 dollar laptop. Here is a link to the benchmark for the i5-760, followed by a benchmark on the current flagship CPU i7-4770k:

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4770K+%40+3.50GHz&id=1919
The i7-4770k flat runs all over it in every category.
UPDATE: I'll try to put it in terms that are easy to picture........
Let's say you're going to war and you have to buy your own gun. Someone offers to GIVE you a Red Rider BB gun, or you can pay 1,000.00 and get an AK-47. Which one would you pick?
I'd pay the 1,000.00 too. LOL
I know....it's a stupid analogy. But it gets the point across.
