I have 2 x 8800 GT from sparkle and had same problem , idle temp 68-73C and when gaming 90-98C (stock setings not clocked), freaking hot and loud , last week i have buyed 2 x Zalman VF1000-LED VGA Cooler, a bit expensive but what can i say , idle temp are 40-45C and when gaming max 60C-62C (even when clocked core clock 647 MHz and mem to 960MHz(eff 1920MHz)it went to 69C @room temp about 20C). about sound ? dont hear them at all more noise i get from case cooler (with is very quiet).but i`m thinking about new rig now, i will start to build next month and i`m 100% sure that i will put watercooling for cpu chipset and VGA card. if you want to stay with this card i think paying 27 pund for extra cooling will be good idea ,but its up to you.
