Dell :: E1705 Breakdown

I've been reading the forums for a while to keep up with the Dell news and now I have a reason to post: my E1705 is failing (like a few others) and Dell's service is..... interesting to say the least. I first noticed the keyboard above the GPU (I have a 7800go) getting very hot while the system was just idling. I fired up i8fangui and read my GPU was exceeding 160 deg F. On idle! I have kept up with bios updates, drivers, blowing the dust out of the system, using the laptop on a laptop cooler or a hard surface, etc. Contacted Dell and they set up a service call to repair the system at my workplace. I was impressed. Then I read the parts they were sending - 2 fans and a CPU heatsink. I nicely wrote back to them that it was in fact the GPU (as I had previously stated) I was having an issue with, included a link to their service manual with a hi-light of the "hot" area. They thanked me for the info and insisted they were going to send the correct parts to solve my issue. The tech showed up with 2 fans and a CPU heatsink and replaced those parts. It was actually pretty funny. He opened the box, showed me the parts, and started to explain just I said "Right, 2 fans and a CPU heatsink. My heat issue is with the GPU." The smile fell right off his face. He was very professional though. Same heat issue when I got home. Emailed Dell again. They then set up a service recall to a depot after I offered to install any new parts needed myself.

System went out on a Friday, back on a Tuesday. I was impressed. Same heat issue and now the wireless card will not connect.... and they downgraded the bios to A06 instead of A09. Opened up the cover over the wireless card figuring an easy fix - just reconnect the wires. The black lead now has a split in the black plastic covering through which silver wire can be seen.... and the temp on the GPU is now over 170. Oh, and the fans don't spin up past the normal whisper quiet either; I used i8fangui to push to high speed to hear the difference. I contacted Dell again though email to the supervisor my previous emails went to and used the Unresolved Issue link over 24hr ago with no response yet.... Getting a little upset. Is this typical and what is the next step people have taken to get their issues solved? I bought a decently souped up E1705 because I didn't need the lights and frills of an XPS system. Maybe I should have.
