Trying to figure why my computer and my friend's computer differ so much on the bench

I ran a benchmark on my computer and my friend's.

I'm going to post my results for both.
I'm wondering if anyone can help me figure out why there is such a difference.

My Computer
Standard Desktop: 13763

Windows 7 64bit
Intel core i5-2500k CPU@ 3.30 Ghz
Nvidia Geforce GTX 550 Ti(VRAM 4049 MB) 9.18.0013.4448
1280x720 Standard Desktop full screen

His computer
Standard desktop :2033
Windows 7 64bit
Intel Core i5-3570k CPU@3.40 Ghz
AMD Radeon HD 6450
1280x720 standard desktop full screen

I haven't been able to figure out why they are so different in score. If I could get someones help please I'd be very thankful.

It might be the video card.

While I'm no expert, AMD Radeon HD 6450 is a fairly old card and not one of the more powerful ones if I recall.

Do you have the same amount of ram?

Is one of you running on a HDD versus a SSD?

It's the 6450 video card. They are basically the equivalent to built in video cards

Comparison of the two cards. The NV is like 3-4x the horsepower of the ATI...and that comparison is just using the base design.

Thank you for the info. I'll let my friend know.
