In a dilemma. Should i buy another 5850

[ninjapug]

I have already spent money on a rig with 3 6970 and 1 5850.

The price of a 5850 is reasonable at usd$140 and soon to be out of stock.

Is it cost effective to buy one more to complete my rig considering the difficulty increase and also i have not breakeven with the hardwares.

It will not be worth it unless you DOUBLE your current hashing power. That is the only way to make sure your earning stay the same with each difficulty increase. But since the value of BTC is crashing, it's probably not even worth that anymore.

Buy as many as you can and either mine with it or sell it on ebay for more money.  I would mine bitcoins with it because I feel like its crashing now... but will explode later on. PEOPLE WILL NOT STOP USING BITCOIN. we are just going thru a phase of muny grubbing investors trying to double their money grubbing investors trying to double their money.

Bitcoin is volitile because all you need is .00000001 single trade to change its value.

To bad it would only change its value after a% amount being sold or purchased.

On a vaguely related note, Do you think it would be worth getting in to mining if I already have a PC that I can leave on 24/7 without worrying about electricity?  (I'd just need a decent graphics card)
The 5850s are about £100 in the UK. I'm not looking to make load of money
Thanks for your advice

I have seen a post with calculation somewhere ... for the price of this card ... should be paids by mining in less than 1 month ...
