Hello. So, it appears my graphics card on my old iMac G5 is toast. I took it to the Apple Store and they said they'd have to replace the whole logic board for around $680. After searching around this forum, that does appear to be the only fix. My question is this: is the graphics card on the newer iMacs soldered into place as it was in the older iMacs (G5 and I believe the first gen Intels as well)? Because, if so, that is really lame and may affect my computer replacement decision. Thanks.
