Bitcoin Mining

Hey folks,

I have taken some interest in Bitcoin mining and am considering making a modest investment in a gpu or two to get a little rig going. I have three questions for anyone who may be knowledgeable on such:

1) Is it more cost-effective to go with one high-end ATI card (say the 5850 series) or a couple lower end cards? I'm looking to stick to a tight budget but also want some decent speeds (the great struggle).

2) How much specialized cooling is required for higher end cards? I currently have an older NVIDEA 8800GTS card which already runs a tad hot.

3) Does anyone have some ballpark figures on their build(s) and Bitcoin income per day? I have heard the difficulty is about to rise with the price hike.

Thanks!

Run the 5850 in SLI with an i7 sandy bridge. You can let it generate via GPU and CPU at the same time. I don't know how it will be profitable as TradeHill gives you 15 USD = 1 Bitcoin and from the looks of it, takes a long time to get 1 Bitcoin

+1 ... why would companies pay real money for some virtual currency you generate out of nowhere?
What's the idea behind this?

seems like my 5870 @stock generates bout ~340Mhash/s. That generates so little coinz lol, gunna take forever to reach 1BTC. Ontop of that its gunna use quite a bit of electricity and puts out heat => AC bill lol.

Nvidia cards suck at mining...

The Mhash rate is what you want to use... My prefered way to cash out is Amazon gift cards... The 58xx videocards are th best

where do u go to cash out? im having a hardtime figuring out how to cashout to paypal

thanks for the calculator, if i throttle my GPU to make less heat, i'll make 2 dollar a day running 24hr lol. (dunno what difficulty factor is, left that alone)

5870 should be making more coins than that... Closer to $6 a day at current exchange rates...

yeah i was saying at a throttled rate, down to approx 120Mhash/s then the calculator gives bout 2 dollar a day. Full speed for my 5870 generates wayy too much heat, im scared the card might get damaged from it.

Just started reading this. Don't have time today to really do my research.

Does this max out system resources? Or can I throw my old mid range video card into my torrents machine which is already running 24/7 and let it do it's thing?

I'm pretty sure it just maxes out your GPU. I've been reading a lot on it and it seems to be pretty hit and miss. As long as your GPU can hash a large amount if you have a better probability to mine a BTC. They are trading pretty good right now as well. Not a bad time to quickly cash in. Or even invest in without mining.
