If you are looking to buy a 5850 i might be able to sell you one if you want (currently pulls in 333mhs at 830/300mhs clocks at AGGRESSION=9, temp at 60c) for about €130. Also have an unused 430w corsair psu that i could throw in for about €30, should be able to run your setup without problem (my 550w runs 2*5850, i3 processor and 2*1tb hdd's without problems, but i believe it's really at the limit and that i am lucky it actually runs it all). The card has been used for 3 weeks about 8-9hours each day, it's an Sapphire ATI Radeon HD 5850 Extreme. Depending on where you live shipping might end up costing almost as much as it would cost to get everything in new condition though.
Anyways, what you should expect to get from this card: with bad airflow in case, wanting to use the computer for other tasks such as watching videos and card at about 60c: 320-340mhs with bad airflow in case, not wanting to do anything else with the computer and willing to go up to about 70-75c: 355-365mhs with good airflow in case, wanting to use the computer for other tasks such as watching videos and card at about ~55c: 330-350mhs with good airflow in case, not wanting to use the computer for other tasks such as watching videos and card at about 70-75c: 360-400mhs
The good airflow numbers are kind of speculation since i don't have good airflow in my case and can't tell for sure), looking at the mining hardware comparison chart on the wiki is also recommended, you'll be able to get about ~3-10% higher mining speeds due to improved miners + small tricks to speed up mhs though.

Thanks for your offer. But I´m at holiday next week, and so, I don´t buy anything now. And the airflow: I won´t have a case. I´ll take the mainboard out of the case. Nils

I believe you can get around ~350-380 mhash at around 70c temperature on the card which isn't really much, i think alot of people go to 80-90c without problems (yet) with the mainboard outside the case (doesn't really help airflow much to now have it in the case).
I think you should go for a 5850 and not 5770 personally, what i have seen it's only around €40-50 more than 5770 and it delivers almost twice the speed, have better resale value if you'll ever think about selling it. Shoot me a PM if you're interested to buy in the future since i probaly won't get rid of the card for some time, not really in a hurry to sell it but if a good oppertunity shows up i'll probaly get rid of it since i won't be using 2 cards in the future anyway.
You can PM me if you're unable to get those speeds (even if you end up buying from store/someone else) and i'll happily help you if i still visit the forums by then.

I changed the title. Because I´ll buy a ATI 5850 after holiday. I´ll install is, and take the mainboard out of the case. The only creepy thing is the power consumption. I don´t think, that a 305W power supply is enough for this card and an intel pentium 4 Can anyone please post any advices for the power of a new power supply? Nils

Make sure your AfterBurner.cfg file looks like this
[ATIADLHAL] EnableUnofficialOverclocking = 1 AccessibilityCheckingPeriod = 0
After restarting afterburner, go into settings and tick "unlock gpu voltage control"

Corsair cx 430w seems to be the best choice of good quality psu with a low pricetag, the 350w might be able to run it depending on the quality, but doubt it will.

Strange: everyone seems to get around 200 Mhsish or more with their 5770, but mine (overclocked at 900) does not go beyond 178-180 Mhs with Phoenix miner, patched phatk, using this script: -k phatk DEVICE=0 AGGRESSION=6 VECTORS WORKSIZE=128 BFI_INT FASTLOOP=false.
Any advice? (More aggression does not increase much the performance and it hogs too much my puter, while at 6 it stays fairly responsive as I need.)
BTW: with this setup temp is at 75-76 C. Should I change termal paste/ increase ventilation, or that's fine?

Perhaps that is not sufficient, you may need this lines, too: UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 Dia

256 Worksize, downlock memory to 300. Overclock MORRREEE!!!! IF you hate long-living cards you can get 1080MHz core
