No need to be sarcastic. Clearly this is a step in the right direction if amazon acknowledges its existence.

Until we see a 20% drop in the 6xxx costs they will not be competitive with 5xxx cards. My hope is that when the 7xxx series is released that's when we will see this 20% drop. If it happens then there would a lot of effective cards that are easy to get on the market.

That's actually pretty cool. Maybe in the future they will be one of the first major retailers to accept bitcoins.

The 5970 is the best way to go if your looking for megahash per square foot otherwise don't bother with it.

A 5830 at 160 is a bad price. You can pick up a new 6870 which is basically the same for ~150. I would not recommend this though.

Your best bet is to wait for a 5830 at less then 130, a 5850 at less then 150 or a 5870 at 190-200.


At the top end of those prices a 5830 gives you 2.54 megahash per dollar. A 5850 gives 2.56 megahash per dollar. A 5870 at 200 will give atleast 2.2 (if its a reference card it would give 2.3)

Another thing you need to remember is the more it costs you for the entire server the more diluted those numbers become. Also keep in mind is sometimes more megahash per server is better then the original megahash per dollar for the card.

I wont say they are easy to come by that would be a lie. However when you go above $150 your reaching brand new 6870 on newegg territory. 6870's require less power and its from newegg. No offense to you but newegg offers a 30 day refund/return on cards.

$162 for a 5830 is extremely overpriced. I hope no one is so desperate to pay that much.

Each 5830 needs at least around 180 watts. 7x180=1,260 watts

That's before you take into account the rest of the rigs power needs. I'm almost positive its because you don't have enough watts. Try doing a dual power supply set up.

You only have 1 1200 watt psu for a 7x5830 rig?

That person isn't the op just in case you didn't realize

Anything close to $150 is not legitimate. 6870's go for about 150 and they get the same megahash and require less electricity.

$400 each is a bit expensive considering all the ones at newegg are under $386 and the cheapest is $340. What makes your cards better then the ones on newegg?

She mentioned that I'd need to know the box size and apparently If you live out side of a delivery zone in another country its another fee added on. So I'd need some more specifics. At least the postal code and your city. You don't need to tell me your address at the moment if you don't want.

Also I haven't seen a 5870 on sale on newegg since early July so unless you know some other site I wont be able to get you a 5870.

I have a relative who works at fedex and she gets 75% off shipping. I would probably be willing to help you out if you pay up front. I would only ask for the cost of the item(s), shipping and like 10% extra for my trouble. If you want a huge amount of stuff I might be willing to drop down from 10%.

I almost bought a second one as well. Glad I didn't

It sucks that more people didn't want to get involved in this. I expected more people would jump at a chance to get a 5830 for 1 bitcoin.

If your willing to mess with the core clock and mem clock you could probably push it to at least 300. Depending on how good your card is it might even be able to be pushed up to 330. I would recommend against changing the voltages.

If your using windows 7 I recently built a 5x5850(sapphire) rig and the screen would freeze if I pushed it too far or tried downgrading the memory to below 500 mhz. Upgrading to 11.7 drivers and using trixx in staid of afterburner fixed all my problems.

That's where the majority of my posts come from

I was going to argue with you and realized it would be stupid. Also I'm sure you ignored my post earlier but just in case you missed it you were wrong in this thread earlier about roi and this isn't the first time I've corrected you.

Its not really a question of what you used but how you used it.

That makes it sound like you have no clue where you were suppose to place it. Can you specify what is the top and bottom of the card.

I'm curious how much your electricity bill is lol. Also how big are you trying to make your farm? You seem to constantly be adding to it.
