I joined because I bought a ztex FPGA and it's the future of BTC. Now I mine 1 BTC per day for 8W, silent and without ecological regret! GPU miners that don't recognise FPGA mining are just bitter. They need one PC per 3-6 cards while FPGA is controlled via USB so you can have 127 FPGA's on one PC!!! Do the math on that and the electricity bill...
How do you like your ztex? I general hear positive comments about them from forum members.
The good thing about FPGA's is their very low power consumption. However, their $/Mhash ratio is also very low. It is really hard to justify their purchase from an economic standpoint unless your electricity rate is very high. Generally speaking, a GPU will net a higher profit for your investment (even when taking into account electricity costs).
An FPGA will currently run you ~$500 for ~350Mhash/s. For that same $500 you can buy 3x 5870 GPUs providing 1200Mhash/s. Yes, the GPUs will be using a lot more electricity. But they will also be generating a lot more profit. And I haven't even brought up the issue of the additional PC you will need to control the FPGA ... but let's say that equates to the motherboard/PSU/RAM you would need to host the GPUs.
FPGA mining boards of today are much like today's gasoline-electric hybrid cars. While they are a very interesting and efficient alternative to traditional GPUs (gasoline cars), their high cost makes them economically unviable in most cases. Unless, again, your electricity costs are sky-high.
I think FPGAs are the future of mining, but that future is not quite here yet. There will always be the early adopters paving the way for them to become mainstream.
Looks like there is a lot off interest
