Fast and reliable, and also very fast. Did I say it's fast?

Summary: Fast processor for an ageing workstation, best if mounted in pairs. Reliable performance with basically any threaded workload you can throw at it. Not so brilliant on single threaded loads, such as emulators and most games. If you work with 3D rendering, simulations, video editing, virtualized machines and such then you'll have very solid performance for the bucks.
Summary: The MAC PRO was delivered in a ruined box with the styro-foam leaking out of the holes torn in the crushed cardboard box. Luckily, the MAC PRO had also been wrapped in protective bubble wrap. The unit only had 1 RAM DIMM loose upon careful inspection. There were scratches on the outer case - cosmetic only. The system came with an original MAC PRO soft white power cord.
Summary: Obviously this processor is not cheap, but you're getting a lot for your money. I'm running two of these in an EVGA SR-2 motherboard, which allows overclocking. 12 cores at 3.85GHz (so far) is a lot of computing power in one box, and because they are 32nm processors they run cool at a little over 60C under load. I'm very pleased with the X5650 and look forward to pushing them over 4GHz. Note: the description is misleading because retail Xeons do not come with a heatsink.
Summary: I'm running two of these in an SR-2 mobo at factory clock. It seems the actual clockrate when loaded is 2.9x ghz? Using Noctua 120mm aircoolers, it is running at 50 deg C on both CPU's under Folding at Home, so there should be plenty of room for overclocking. Expect power consumption of 360 watts or higher while folding with this setup. In comparison, I have a 2x E5620's that consume 255 watts when folding.
Cons: I’ve got this CPU with a purchase of used Dell Precision T7500 in a dual CPU configuration. With HT enabled Win 7x64 reports 24 CPU cores. I run simultaneous conversion of ten AVI to MP4 video files. Each file is about 13 GB in size and this process was completed in less than 30 minutes. CPU usage never went over 30%. It’s amazing. I run a single file conversion on another machine with a dual core non-Intel CPU and it took hours and CPU was at 100%.
Pros: It came on time as promised, but my motherboard is a day behind for some reason, from the rest of my purchase. I won't be able to build my system until tomorrow, but they got everything here on time basically, as promised. I ordered late Saturday night, it shipped out Tuesday, and got here on Thursday. I would like to note that Friday shipment is still within their promised service time frame, so no complaints on that end, even if it is at the far end.
Cons: It does not come with a heatsink or fan. If I had known that, I might have chosen other options. Now I will have to look locally for an option, or possibly even send it back. Shame on them for not telling. The package came in apparently good condition.
