    Nope, popped in another card no problems. Had my 8800GTX in there before the HD4870 for 2 years without a problem, all the same hardware. Honestly the HD4870 seems like the Wolfdale cores - they just can't play hard or they die. The first card had issues from the day I got it. Would just lose signal and shut down while the PC was still on. It finally died on me without overclocking or doing anything much with it.

    The VRM temps are very high which I feel leads to a quick failure. Also the DDR5 runs hot on these cards. I had a fan blowing over them and the ram sinks still got pretty warm, much warmer than my 8800GTX ram sinks ever did. I believe the high temps of the ram and VRMs attribute to the high rate of failure with these cards. The failure rate for the HD4870 is pretty high if you look into it. The card wouldn't let the PC post (beep) so it wasn't even an issue with drivers or overclocks as the card boots up in 2d settings. Once I swapped for an X850XT PE PCI-e it fired right up. Tried a few things, spent the better part of two hours messing with it, nothing, no beeps, no post. Was fine last night and I was playing COD4 for about 2 hours.

    What really bothers me is having to change GPU blocks out for the GTX 260. I just rebuilt the water cooling setup about 2 weeks ago. grr.

    Anyone looking to buy an HD4870 - really consider the reliability factor with these cards. Might be better to stick with HD4850, lower VRM heat and DDR3 seem to be a better bet.
