hi, i've not done the memetest86 yet (will do while sleeping), but i tried some gaming and i had run through an annoying issue
So in BF3, assassin's creed and especially Star wars the old republic every damn time my fps fluctuate results in some sort of stuttering (like ms halts), i said especially SWTOR because the fps are very unstable in this game.
The problem is worse at low fps of course but i get this thing even at 60+ fps, for exemple going from 90 to 80 does it
After that i tried Rage which is always at 60 fps (the game itself can't go higher or lesser) and this is smooth as butter!
I want you guys to know that i play on a Asus 120hz monitor without 3d glasses and that i tried it in 60hz but that was worst. I never play with vsync on but tried it and even if i know that vsync off i have 80 + fps, when vsync on my fps drop to 59 or 61 all the time.
Now i don't know if i should blame me for the scratch or my gtx 580.
