I just got my Gigabyte HD3870 and went ahead and install to my computer. My 7800GTX is now retired and I will be selling it on Ebay. Ebay upon getting the HD3870, I tested it on my pc and works really well on my games and the perfomance is significantly better. At 1280x1024 resolution I was able to crank the COD4 game settings to the max and frames rates are over 50fps. I have the V-Sync on for 60hz monitor. Also using the Vista 32-bit, 840 @ 4Ghz, 2 Gb DDR2 533 @ 400Mhz.
I have the Kandalf case and it's equiped with a 250mm side fan. It's cool enough, and the stock cooling HD3870 idles at 34c and full load of 70c. I went ahead and install my old Zalman VF-900 cu from the 7800GTXs to the HD3870. I didn't have to remove the HD3870 ram heatsink and the other heatsink next to it. I just remove the stock GPU cooler and is now replaced with the VF-900cu. The results are from playing the COD4 at the settings above as I mentioned, I get 32c idle and 45c full load. Yes! 45c full load on CoD4, 1280x1024 high settings.
Alsow the VF-900 is at medium speed and i can control the rpm with it's controller.
Cheers.
P.S. I don't know how to insert the images I took of the card and the VF-900. Please let me know how to do this and I'll be happy to post the pics and results.
