Graphics Card upgrade for M6800 ?

\now for something completely different ......this came up today on my M6800 ....... what hardware wise could cause a machine to sort of mini freeze every ten seconds or so,,, I am tearing my hair out ,,,, I know its hardware because happens on two OSs on two separate hdd ,,,,... I have taken out memory, hard drives, changed the video card then changed it back.......this is driving me nuts

 

I've had stuttering like this when the battery is going out (believe it or not), have you run with the battery removed?

 

ill try that ,,,,,

 

I recently had to replace a cracked screen------- I am certain I was sold a loser as that explains every bit of this strange behavior. I just never considered I had been ripped off. If any of ya'll know a good source other than ebay to get one of a fair price I'd love to hear from you

 

You want to get a common 17.3" edp lcd ? you could upgrade the M6800 up to 4k monitor if it have a 40pins eDP cable, like on the M6700 I think

 

I wouldn't even begin to know how to tell, but I just want the 1920 x 1080 display I had, without the stuttering

 

I have good news or bad news depending on y'alls previous stance on the quadro p3000 working. i have a m6800 lvds model. i am very sure i am using the lvds motherboard and screen because i upgraded it myself. the bios is just a generic dell vbios downloaded from techpowerup, and i custom modded the driver inf but otherwise i just plopped it in with my nvidia variant 2 heatsink and it booted straight to windows and works perfectly fine. i know my account is new but i made it just to post this because so many people said it is impossible i wanted to let y'all know it isn't, i've done it.

 

Screenshots are far more powerful a statement by than any account history can provide.

 

How'd you flash the vbios? Do you know what system BIOS rev your M6800 is using?

 

The only P3000 vbios on techpowerup is the one that is supposed working so it's not shocking for me.
Could you provide some proof ? including GPU-Z screenshot and a 3dmark firestike result ?
Thanks you
