maybe, furmark should still be stressing out the cards to show its max temp, i mean on guru3d where rivatuner was made, they run furmark at 640x480 in windowed mode while slowly upping the clocks with rivatuner. And they go by the temps they see there and watch for artifacts while they increase. So 1280x1024 should be fine.
