Few different cards in 1 pc

[den11111]

Need your help!
I want to buy second-hand cards:
ASUS HD5850
Sappfire HD5850
Gygabyte HD5870

But I think it will not work under win7
If this will work .. can I overlock every card separately?
Help please

Software generally isn't an issue, there are drivers, and you can use MSI afterburn on multiple cards. Do you have enough PCIe slots for the cards?

It will work. Provided you have enough PCI-E slots. If you use Windows 7 you'll need dummy plugs in order to make the cards that don't have a monitor attached boot up. Other than that it should be smooth sailing and Afterburner should allow you to overclock your cards.

There are 4xPCI-E 16x on ASUS M4A79 Deluxe.

Anyone tried a similar configuration in linux/ubuntu?

ASUS Radeon HD 5850 overclocks pretty well with included Smart Doctor utility, pushed mine to 385 MHash/s. I use nVidia GTS 450 as the primary graphics adapter at the same time, a dummy plug works fine for the mining card (btw I didn't have resistors, so had to use just a piece of wire instead). In linux only hardware overclocking using a custom is possible (correct me, if I'm not right, I don't know gpu overclocking software for linux), so better take reference cars, or you may face problems flashing BIOS.
