I have that same guitfiddle. For being cheap, it sounds amazingly good and stays in tune as well.
Desktop has an Intel Core i5-2500K OCed to 4.6GHz, 8GB DDR3 1600MHz, Sapphire Radeon HD 6850 1GB GDDR5 OCed, 2TB HDD, 60GB SSD, and it dual boots Windows 7 and OS X.
I like all of the above. Did you have any trouble with the Hackintosh aspect?
