7970: Currently $405USD, ~700Mhash, 250W, warranty 1+ year from many reliable manufacturers available instantly, resale >$200 if sold in 2 years. Also play games and act as GPUs... Return on investment time: Dependent on your local electricity prices. Block reward halving in 7 months...

Fill in the gaps for other devices.

Note: I only have GPUs.

Where can you find 7970s for $405?

FPGAs are a decent investment for someone in my situation. Central Valley California stuck with PG&E. Top tier electricity rates are at 0.34/kWh (it was actually 0.40 last summer!). During summer, I will be locked into top tier pricing just because I have the nerve to set my AC to 75-78F instead of 85F+.

At those prices, GPU mining is a loss for me, even if you don't include the extra power offset the additional heat.

No way man. FPGA is the best thing since sliced butter.

Oh and them BFL wonder boxes are tasty as peanuts !

I get the feeling that everybody is saying "GPU is dying" so they can grab them at a cheaper price ...

I will be laughing at the FPGA folks with 20 or so useless boards when the gold dries up here Cheesy

If you wait long enough, something better will come around

But, once that comes out, if you wait long enough, something better comes around

I have to wonder what the logic is here. Have people done a true and thorough economic analysis on these? If you take into account their cost, salvage value and the rapid development of the technology, it looks like people are just paying to be beta testers.

It seems to me that newer boards are coming out almost weekly at this point and some obviously larger players are entering the market. On the current trajectory it looks like we will see boards with 4 chips doing 1000-1200 mhash for probably 600 dollars by year end. Considering the average ROI on most of these is around one year, won't the current boards be obsolete by then ? I can see boards in one year doing 3+ Ghash for around $1000.

Thoughts?
