Pros: Fastest single GPU on the planet. (including fastest GTX 580 stock OC clocks) The Arctic Cooling Accelero Xtreme Plus cooler is as silent as you're going to get on air. The Sparkle Calibre series GPUs also come with a superior VRM cooling heatsink than Arctic Cooling themselves offer if you decide to buy a standard GTX 580 the cooler as an aftermarket add-on (MSRP of $81.54 + Shipping to buy the cooler and GTX 580 mounting kit). Reference Nvidia PCB, so complete peace of mind that you aren't making a bad choice even if you aren't familiar with Sparkle. Lifetime warranty, and English customer support located in California.

Cons: This card takes up 3 PCI slots, please be aware of this obstacle if you plan to SLI.

Overall Review: It's a shame that this product was discontinued so quickly. Sparkle announced a non-reference version of the Standard GTX 580 on 12/15/2010, so I hope they will continue the Calibre series production with their new PCB so more folks can enjoy this utterly amazing GPU.

Pros: The orientation of this PCI cooler works great for cooling the back of your GPU at the same time as moving lots of air out of the case.

Cons: NOISY.

Overall Review: In the end I decided to yank this product from my system. The noise from this cooler negated the benefits IMO. 16dBA? Get real. This thing is louder than a high end GPU at 100% fan speed. If you already have a noisy system and just want to move air out of your case, it's a good product for the price.

Pros: Fantastic price, very stable. Works perfect in my Mobo despite not being in the Supported Memory List.

Cons: Could have better latency, but you know the specs when buying. Not really a con in that respect.

Overall Review: I purchased 4 of these sticks for a total of 16gb. I had trouble with one stick in memory tests, but it had signs of physical wear and Newegg promptly replaced it fast and painlessly.
