Laptop:
Core2Duo 1.8ghz
1gb RAM
1500 khash/sec on CPU
?? khash/sec on GPU (it's intel video card, doubt it can do GPU)

Desktop:
Intel® Core™ i7-870 w/VT
8GB RAM
4500 khash/sec on CPU without limit
5000 khash/sec on CPU with limit to 4 cores (why is this higher?)
3500 khash/sec on GPU (I thought GPU>CPU?

1)Why is limiting to 4 cores faster than no limit (on 8 cores)?
2)Why is GPU slower than CPU when ppl say GPU is supposed to be an order of magnitude faster?
3)Why is my Core2Duo 1/3rd as fast as my i7 when my i7 has 8 cores vs 2 cores and a lot more ram/better architecture/etc?
