i think there is no problem crossfire with different model of 3870, crossfire works differently compare to sli. you can CF with 3850 too, so ur old card will never get wasted...... hehe

8800GTs 320mb > 3870 have quite some improvement espeacially on large resolution, 320mb of video memory os too limited.

FPS wise not much increase but u get a better image quality in display

sniper, 560w is more then enough...... check my signature.....

i remeber legionhardware or xbitlabs measure the power requirement for crossfire and a xtreme procesor max out around 400W only, still got plentiful to spare

zhen-wei urs on crossfire ??? btw mind to share the resolution, seems to be a good score.

well frankly 8800GTS 320mb to 3870 u wont expect a lot of difference in fps, but rather smoohter image rendering and better gaming experince. but the extra memory is realy useful as most games need around 350mb of video rams to run properly nowadays

most important the image quality at large resolution when u zoom in and out frequently as do in recent RTS games. Nvidia cannot compete here,

the price for 3870x2 is good, but the cooler aijor...... very disspointed and the power requirement is also killing......

i was thinking of getting a 3870 and 3870x2 together 1..... but i think it's not possible now.... PSU tak cukup power.

butthead, 2 3870 may outperform the x2 if u have x38 chipset, else may be not working as well.... x4 is really limiting the card ability
