I am new to all of this and I am wondering if I have a decent rig to mine any type of Scrypt Coins.
http://pcpartpicker.com/p/2hM1cPlease share with me what part of the hardware counts towards kh/s and if I should upgrade.
If you have a decent rig I'd say look into mining a scrypt altcoin. I'm not sure which is best for you, that is something you'd have to look into but it could be worth the time in the long run.
Well, they did post here saying they want to mine exactly that, Scrypt-based coins, and that they wanted some tips on their rig which they posted, not 100% sure if you actually read the post O_o.
To OP:
Now as the other guy said, the 280x's are good but very power hungry, so you definitely want to see if you can find some 7950s because they produce very good hashrates while balancing (fairly) decent power requirements.
