Quadro FX 2700 losing textures and glitches

Hello. I will try to make this short and brief.
Computer: M860tu , previous card 9800GT died, new card FX 2700
New card worked fine for 1 month with no gaming problems, except a few minor glitches, no updates to bios, just new gpu drivers.

After aprox; 1 month of installment:
When playing 2 clients of EVE online at lowest possible setting the game freezes a little bit then it shows texture losses, rendering issues. I check my temperatures in speedfan and EVEREST.
GPU : 60-65 c
HD : 52
TEMP1 is at maximum 67 C usually around 65
everything else is below 65.

When playing starcraft 2 at low setting I can play for hours, after it gets warmer in the room flickering occurs.

Tested solution.

tried multiple different driver from official to non official (nvidia 2 go and nvidia.com) = not successful

Updated BIOS to latest = not successful

lowered resolution, and running 1 client = not successful

Not yet tested:
Disassemble and clean entire pc ( already did when appyling the new gpu )
Re paste
Buy ( already bought and on its way) Thermaltake cooling pad

Overclock and overvolt with MSI Afterburner ( will it really help ? )

Last option: Screw it, Im buying a new comp.
