Anyone have a good researching site??

Wasn't sure which forum I should post this in, so 'Questions' seemed appropiate, lol. I was searching through anandtech and spotted this post: AnandTech - NVIDIA's GeForce GTX 560 Ti w/448 Cores: GTX 570 On A Budget about the gtx560ti w/448 cores. My question is if you guys know of a good site to help explain all the specifications on that page (ROPs/ Core Clock/ etc.) I'm sure I could google them all individually, just wondering if there was a place that addressed them all...
Thanks.​
