I am also ne to bitcoin and really confuse what does R9 280x toxics up to 800 Kh/s (running 3 in a rig I built atm) for a total of 2400Kh/s means or about XFX R9 280. I would really appreciate if you tell me about it in plain English instead of technical words. Or you may even give me the link of some reliable site so I may attain basic knowledge regarding its functionality

When he says 800kH/s, I'm assuming he is talking about script mining, else we will be talking in MH/s.
the kH/s, MH/s is the number of hash per second, the higher it is, the better.

The R9 280x or XFX R9 280 are graphic card, which are good for mining.

Here are the comparison for differents hardware.

Mining are for people who want to invest into rig for mining, then selling afterward.
You can also invest into bitcoin/litecoin or any other currency, but it's like trading, you may win fast, you may loose fast. Mining is slower, but "safer". Take into account the electricity bill, and the hardware cost.
