Thx Pcgeek..

well am not going to push it anyways was just curious abt the sudden change in the temp..
saw Ati Radeon Hd 4650/70 512mb DDR3 for abt qrs650/- cant make up my mind should i wait for a while or just get it.. 9800GT/X is not available in the market, 9600GT 1Gb for abt same price as HD 4650 and 9500GT 1Gb for 400/-

can i use any different models like 4600 and 4800 series in crossfire?
