Hello,

Well recently I had problems with my new GPU.
Where my 'GTX 650 1GB OC Edition' used to drop fps allot from 40 to 5 and shoot back up to 35 - 40 every 10 - 15 seconds.
I thought that it were CPU problems, but now I changed back to my old 'HD6570 1GB'.

BOOM everything worked perfectly!
No lags, no fps drops, no nothing. (although I had to set the settings lower for some games).

How can a HD6570 beat the GTX650?
Because I'd prefer to use my GTX650, supports more stuff.

If anyone has any idea on how to fix it, please let me know.

Thanks

Alright, is there a way to fix it manually?
I don't think I have any warranty left...
