I believe if you have a good FPGA rig now, in hand, hashing at least 2 Gh/s then it is viable. otherwise, start saving for an ASIC Smiley

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

As the ASIC miners hit it will be more difficult to mine SHA-256 currencies with GPUs, but Scrypt-based currencies like Litecoin and Feathercoin are designed to be CPU and GPU friendly because they rely on memory-intensive operations. It'll be difficult to develop ASICs for those. Kevin De Angelis just created wheretomine.com to help people understand what the good mining opportunities are at the moment.

I'm happy with my Quad 7950 rig. It's been running over a month now.

This is cool!  I did not built a rig but use my game computer to do part time mining.

What are the specs and hash rates?

I don't think they're dead yet, however, in a few months I believe it will be an entirely different story. I just bought a few 7970s with a buddy of mine, and we got a really good deal. I already had a motherboard laying around that has 5 PCI-X slots, and own a few solid supplies, so I've only spent money on GPUs.

Also, I don't have to pay for power, so, in my case, I believe there is still a benefit to GPU mining. Furthermore, I believe that I will be able to sell the cards I acquired for more than I paid in 3 months time, which will pretty much guarantee me a profit.

GPU mining is just fine ATM, maybe not the best.. but if your active in your mining then you can make some profit

GPU Mining is almost unprofitable unless you have free energy and the location you don't pay for. Which would be most High School and College Students.

My work colleague and I are IT professionals; have been for several years. I had been GPU mining for 1 year on my crappy GTX 450. Took me about 6 months to get 1 BTC. And then the bubble happened and I really got into things.

I live in Sydney, Australia
I pay for Power

At this current difficulty we are barely making a profit at 4GH/s in about 4 difficulty changes (2months) we will be loosing money.

But its been fun setting up the computers, working out all the issues. We are looking to move to ASIC's because of their speed and power draw over GPU.

So for the next 2 months; if you pay for power in Australia...  .... ..... you will be ok till then.
