OF course. The stock coolers are currently mounted; I put them back on after getting my 4870x2. The pic in the first post is of them taken after the thread was posted(damn camera battery was dead). I can toss up more pics if you like...just tell me what you'd like to see!
Both card do over 925mhz gpu on water, and the cards have never been modded, either for volts or bios.
A single card is a great performer...HDMI works fine(they came with adapters). It's comparable to a 4870 512mb, which was a bit shocking to me considering 4870 has 800 shaders, and 3870x2 has 640, but the 4870 is on new drivers, and new cards typically take about 6 months before the driver becomes good.
Quad gpu is a slightly different story though. I wasn't satisfied with that at all.
Block comes with the card whether you want it or not.

Once the card is gone, I have NO use for it!
