[Elijah]

Its been some days that I have a problem of lag while playing. As soon as I start the game, it started lagging in the presentation. I tried with a single graphics card and it is consistent.

Motherboard: MSI DKA790GX (bios 1.6 version)

but the days with the 9.4 driver. On which game you lags?

Possibly your power supply is not at all good. Use OCCT or some other software and see the voltages.

But as a first step, I will change the power supply to something more reliable (Corsair, Seasonic, etc ...)

I did not know which was the other drivers. It's on farcry 2. As against I did it anyway 18500 point on 3DMark06.
