Priced at $1050, with free expedited shipping by DHL. http://cgi.ebay.com/XFX-Radeon-HD-6990-4GB-DDR5-Ideal-Bitcoin-mining-/170659124755?pt=PCC_Video_TV_Cards&hash=item27bc139613 Any questions feel free to ask either here or via ebay. Cheers Title: Re: Selling my new xfx ATI 6990 card Post by: wazoo42 on June 23, 2011, 05:28:16 PM They have 2 cores, so cut that in half to compare with most cards. Also, they are selling from retailers for $600-700 USD (according to froogle).

did you buy this new from circuit city? i'm just wondering because that seems like a lot when i see them on the elsewhere new for under 800$. Title: Re: Selling my new xfx ATI 6990 card Post by: matt_b on June 23, 2011, 05:52:54 PM The 6990's look to be the best bet as far as max hashing power per motherboard. You should be able to run 3-4 6990's on one computer (with a good PSU). However, you need to factor in the difficulty increases, cooling costs, and power costs when deciding how long it will take to break even.

Im selling at cost price as purchased at a high tag price already at $950 due to scarcity i guess.. Add shipping costs from $40 to $60 depending on continent ,and the astronomical fee of $55 ebay charges for that sale Anyone interested for a direct sale without ebay, i can trade the card for $990.

You should be able to run 3-4 6990's on one computer (with a good PSU). Using the 6990 is great to concentrate megahashes per slot on the motherboard. But at over $1.00 USD per MH, it can cost twice as much on a per MH basis than other cards. If you are not looking to stuff a single motherboard with as much power as possible, using a few 5830's or 6870's gives you more bang for the buck. Title: Re: Selling my new xfx ATI 6990 card Post by: freezed on July 01, 2011, 03:53:56 PM Comparing the 6990 to other similar mhash boards like two 6950/6970's: -Consumes 375W at stock 450W in OC mode; two 50/70's consume 500W in total without any overclocking (much more if OC'ed) -Better resale value Any takers? i'm pushing the price down to $980 for a direct trade.Will ship for free.

Well, shipping isn't exactly 'free' as you say if you're including it in the price. It's just included in the price... ;)Title: Re: Selling my new xfx ATI 6990 card Post by: Silver1988 on July 01, 2011, 05:42:01 PM I can buy a 6990 from NCIX for $685-$750. ???
Title: Re: Selling my new xfx ATI 6990 card Post by: Quix on July 01, 2011, 06:50:32 PM If anyone here wants to waste $1000 on a 6990 I can drop ship you one.
The reason they're scarce is that they're no longer produced. Super high-end cards never sell very well so they only make so many. Since AMD is just about to release a new generation of chips the 6990 is going the way for the old 5970.
