Get a used 5850 for $150 or less

I currently have crossfire 5850 in my system and with a decent overclock can reach about 660MH/s

At least?
It doesn't even reach 300MH/s each at stock.

I have mine clocked at 775/1125 currently, I can't go higher without it overheating. I'm already at 100% fan speed.

Crossfire 5850 580 MH/s

It would be nice if you could make a short formula to make an approximate calculation of how much users can be paid over the course of 24 hours, with a few variables incl. # shares/hour, current reward per round, etc...

I've already noticed that slush pays out far more than deepbit over the same amount of time. I've only been mining on slush for a few hours and I already have 1 BTC. Compared to the ridiculous 2.5 BTC/24 hr on deepbit -__-

How do I manually pay out the BTC to my address? Is there a "send payment" link...somewhere? Or does it just have to reach the threshold?

I got my XFX 5850 at about 360 MH/s at 970/1250. I thought this was a "normal" speed.

So, 100 solved blocks later I will know how much I've made?

I actually like Deepbit's system a lot better. It's a lot easier to keep track of earnings. But if slush's pool yields higher rewards, I'll wait the 100 blocks.

Quad crossfire 5970's with a Sempron 140 and 1gb of RAM?

Are you serious?

At least put an i7 in that system. Go with Sandy Bridge even or wait for Ivy.

Alright, so I've been mining on slush's for about three hours and the values for estimated rewards and unconfirmed rewards has been increasing, but when will the confirmed BTC show up?

And how is payment calculated? I switched from Deepbit (the rates were getting ridiculous, it dropped from 0.0004 to 0.0002 to 0.0001 over the past few weeks). Deepbit had a proportional/PPS payment system, but slush's pool doesn't even specify how users are paid.

My current 2x 5850 crossfire setup yields about 330 mh/s at 900/1150. The temps are a little out of control so I have it running at 775/1125 right now, yielding 290 mh/s each.
