Poor i5 2500k and GTX 580 3dMark11 Score?

[ngoing001]

With stock speeds I got a score of P5937
After I OC'd to 4.8Ghz with 1.415v, this was my score:

It's telling me my score is unusually low for both times I did it, stock and 4.8

This is my current setup:
i5 2500k
Gtx 580 DirectCu II
8GB DDR3 1600Mhz
Corsair 750w
WD Caviar Black 1TB
Asus p8p67 Deluxe
Xigmatek Dark Knight

That's not a poor 3dmark11 score.

The only reason it's going to say you have scored low, is that most people running 3dmark11 and posting results, are those with highly OC'ed setups and it's the video card that makes the largest impact of your score. That's actually a good score, even if you could get higher by OCing the 580.

I just got P5968 with a 4.8GHz 2500K and a mildly overclocked 570 (820 core, 2100 memory).

Scores -- mine (yours):
P5968 (P6017)
5604 (5610)
9027 (8914)
5847 (6384)
24 (24)
25 (25)
35 (35)
18 (18)
28 (28)
27 (29)

It says my score was Comparable to Similar Systems. So yeah, graphics card overclock really makes a difference.
