When my new/used 680m card arrives then I would like to stress-test it to see that it works 100%. So I would like to ask what's the best way to test a GPU and know that it runs flawless, some graphic test program or just try to play a game at ultra settings for couple hours ? Any suggestions are appreciated.

After I read through this entire thread I tried to revert my M17xR4 from the latest A12 bios. Before I used Flashdrive method I simply reverted Bios to A08, think this might be importent. Then I just followed the guide step by step and it worked flawless. Just don't turn off your computer when it beeps and the fans are at full, it took 10-15 minutes while at that state before the pc restarted.

Are you sure that the lag is only in LoL or have you tried other games ping also ?

Thanks a lot. Found a 680m together with a heatsink that fits my R4 so I ordered.

Hi I currently have a M17x R4 with a GTX 675m that started to BSOD on me a month ago when I installed at that time latest Nvidia drivers. From what I have been reading is that NVIDA screw a lot of people with that card as I can find a lot of post with mad people with broken 675m cards. So I'm thinking of a GTX 680m. My question is this: My 675m cards processor is rectangular and I see a lot of GTX 680m cards on Ebay with a square processor. Will my heatsink fit ?
