How's your bitcoin mining per day if you don't mine me asking. My gtx 560ti is OC to be on par with a gtx 570.

I wouldn't worry bout mining with my CPU I am using a aftermarket cooler and I OC it so I ran prime 95 for over 10 hours stress testing it which means it is constantly at 100% and my temps stays at the low 30s-mid 40s. I am more worry bout my graphic card I stress test it and it peaked at 70 degree Celsius. Also I mention electricity isn't a problem. So any guides and tutorial to mine with a nvidia and intel gpu/CPU.

How would I be able to start mining with a nvidia specific card?

Electricity is covered in my area so it isnt a problem. I am also wondering is the Gpu is consistently running on 100%? Also it's not worth mining with a quad core CPU at all?

So is it worth the time mining with these specifications?

I have recently stumbled upon the idea of bitcoin mining and I have 2 computers which I can mine with which specs are a i7-2600k and a 9800 GTX+ and a Q6600 OC to 3.0 with a OC GTX560Ti to a GTX570. I heard these spec's were rather bad to mine since its not AMD based and the CUDA software was out of date? If its possible to mine with Intel and Nvidia based cards and CPU where can I start. Thanks in advance.
