Was making about 1.3BTC a day on Slush before the last two difficulty increases. Now it's about 1BTC. Trying to decided if I should keep at it... at least until I've paid back the price of the hardware (about $400).
I made the mistake of solo mining for about a month when the difficulty was still at a (relatively) reasonable 150,000 or so. Didn't find a single block, which in retrospect is not surprising. Would have been nice to have made some BTC during that month in a pool, but what can you do!
About 800 MH/s. That's with two 5850s running at 900/350 (about 360 MH/s each) and a 560 Ti at stock (80 MH/s).
They all hover around 60C or so. A screen cap from a networked rig monitoring app I'm currently coding for Windows. It has an embedded HTTP server so you can view your rigs remotely:
