I purchase this card for a new pc I build from scratch . spec on my gaming rig be thus : ASUS P8Z77 pro board core i7 2600k Sapphire Radeon 7870 OC 2gb 16 gb RAM Corsair Vengeance black Samsung 830 128gb ssd -lrb- system + only major app -rrb- Seagate Barracuda 2 tb 7200 RPM HDD Cooler Master tpc-812 heat sync Cooler Master HAF-X Blue Edition -lrb- newegg exclusive -rrb- + all fan for all fan slot Cooler Master silent pro gold 1000w power supply Sony dvd burner win 7 64-bit only run a single monitor , 24 '' ACER on the DVI port Processor temperature do not get too high nor do the video card temperature . in fact , my box stay very cool . Processor idle temp be 29-31 Celsius . when play Skyrim on ultra , the processor can get to 57 Celsius . I have 2 fan blow directly on my GPU as well - one from the side and one blow toward the back of the computer . when play game for long period of time , 3 + hour , at least once in this time period my screen will go black -lrb- video signal be lose -rrb- , the fan will spin at max , and the only way to stop this be a hard shut down by hold down the power button . there have be a lot of document case online . just search for `` Sapphire 7870 crash '' or `` Sapphire 7870 black screen '' and you will see page of precisely this issue . apart from these crash , this be a good mid-range card . it run at low temperature and deliver good frame rate . however , the constant crash have leave a bad taste in my mouth . since it be be over the 30 day with Amazon , I 'll see if my credit card company will refund my purchase . I really want to like this card base off of the review I read at Tom 's hardware and other source . but the regular crash make keep this card untenable . I have also read that people who have RMA would this card still experience the same issue with they replacement . I 'll probably end up go for the EVGA GeForce GTX 680 with the dual fan . this have be my first experience with radeon on the pc and with Sapphire Technology card .
