question about AMD vs. Intel

[Namelessv1]

I'm planning on building a new rig on a budget, but I don't know whether to go with an AMD Athlon 64 X2 5600+ or an Intel Core 2 Duo E4500. The AMD is clocked at 2.8 GHz while the Intel, which is ~$100 more with appropriate mobo, is only clocked at 2.2 GHz.

Is the Intel worth the extra money, or should I just go with the AMD? I'm not planning on overclocking.

I've tried googling for comparisons, but all I got was a bunch of "Intel is better than AMD" responses, or vice versa. I also checked Tom's Hardware CPU chart, but it doesn't list the E4500.
