Besides the upcoming ASIC technology that allows GH/s....when they ship them.

what are in stock now that is worth it?

what is the best thing to buy right now? I mean, something that is already in stock, like https://www.btcfpga.com/index.php?route=product%2Fproduct&product_id=50

any more products out there?  and I mean 1 device, 1 rig, ...not having to buy 6 cards and rig them myself.

Thank you all

btcfpga is instock and will ship, I believe BFL is still filling back orders from aug? If you were to invest in fpga you are kind of screwed no matter what since for BFL you won't get it until maybe next month and for btcfpga there isn't a clear buyback program (yet).

To be honest if you are just waiting for asic, probably getting a few 7970's and hashing them until asics is probably best. You can then resell sell in a few months and hopefully not lose too much money.

Don't bother buying FPGAs right now at all (unless you're going bfl and getting the upgrades purchased at the same time).

I'd look at picking up some 7990 ( or 7970x2 ) cards. Should be able to get between 1gh/s and 1.4gh/s. Then run them until asics are out and the difficulty shoots up - at the point where you see a 50% loss in btc generation, then you should sell the cards (should have held 80-90% of value) and purchase asic product.

If you'd rather not rig them yourself --- let me know - I'd be happy to assemble, custom cool, overclock and ship to you.

I have no idea about how to rig. How much would it be for that?  would you recommend 7990x1 or 7920x2?

Ditto I have no idea how to rig either! Can someone teach me?

7970x2 and 7990x1 are the same card... It's basically a single slotted card with double the 7970 hardware on it - doing internal crossfire.  the problem is AMD didn't make a reference board for the 7990. . . so the video card companies are making their own. The only reason to specifically get these cards is they're top of series - and will hold value much longer than others in the series.

what's your over-all budget for the whole thing? Let me know and I'll get you a quote on what it'd cost to put together.

Thanks...but I think it would be out of my budget. I was checking prices and two cards, plus your cost, would be too expensive. I may go with 1 card then.

Thanks for the info!

Im getting my setup soon, How do you overclock the 7970 ?

Thanks!

Glad I could help.

If you don't know how to build, could buy a pre-built already tested rig

Selling my 2.1G/hash/s rig. it should be able to handle 3x 7990s just as well as 5970's, so it could be almost 4Ghash

Modminer MMQ may be the best miner to buy right now

Isn't it the only FPGA that you will actually get right now within a reasonable timeframe?

but can get a used bfl single for less for almost same mhash, just a lil more watts

well you see, there is this thing called the internet, lots of stuff you can learn on the internet, particularly about computers
