From this calculator: http://dustcoin.com/, you need about 60,000 KH/S to make $114 a day (excluding power cost). One of the most efficient $/hashrate GPUs for litecoin mining is the ATI 7950 at about $210 a piece and ~600 KH/s. 105 * 600 KH/s = ~60000 KH/s = ~$114, so it works out. That's $20,000. So if you spend $20,000 you can buy yourself a job that pays $114 a day. It will take 6 months just to break even. Better hope the difficulty hasn't increased enough in that time to make your GPUs irrelevant (hint: it probably will).

Keep in mind that I was very generously excluding the very significant cost of power, the very significant cost of all the motherboards/cpu/ram/power supplies to run those GPUs, and the power and space required to cool them. Realistically we're looking at more like $50k.

>“Currently I’m making about 60 litecoin per day,” he said. “I’ve kept 95% of the mining profit since April and once the major exchanges start accepting LTC, others will follow, and price is expected to soar. So that 60 LTC could turn into $1,500.”

This is absurd. If he thinks 60 LTC will be worth $1,500, he should spend the $20,000 he spent on GPUs on LTC instead. He'd turn $20,000 into $250,000 with no work required (another hint: assuming you can turn $20k into $250k in 6 months with no work as a sure thing is also absurd).
