***Genuine NVIDIA GeForce GTX 280 Engineering Sample (A1 Revision) Review***
http://img709.imageshack.us/img709/679/dscn2054.jpg
Introduction
This card was "accidentally" discovered upon purchase of a mystery GPU (looking like a GT200 series video card) located on a bid on eBay. Link Here (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160383349666). Originally I purchased it expecting it to be some dead GT200 series GPU just so I could try out the oven bake method and see if I could revive it. But upon reception of this GPU, I had noticed it was quite unusual in some ways. In most cases it was resembling a GTX280 because it had a backplate and also an 8+6 pin power connector configuration. The best my guess would have been is that this is an OEM GTX280. However, first difference I noticed is that there were no stickers or marking on it what-so-ever. Secondly, this card had a silver aluminum top sink (which was never seen before). Thirdly this card seemed to be heavier and made of a much higher quality than the previous GTX280's I have worked with. Upon further inspection and detailed Google searches, I realized this was no ordinary GTX280.
It appeared that I have just received a Genuine NVIDIA GTX 280 Engineering Sample, and not just any engineering sample but an A1 Revision (meaning one of the first GT200 video cards ever made). Of course you can expect I was a little skeptical and I had thought that there would be no chance this video card was working. So I decided to give it to a friend of mine to test it while I was away. And surely enough, the card POSTed and booted perfectly fine into Windows. Soon as I came home I decided to disassemble it and take a close look at what this thing looked like from the inside. Let's see what this thing looks like:

First Impression Detailed
Straight on first inspection, I could tell this thing was unusually well made. The quality of the parts they used to build this thing was unlike I've seen before and the cooier looked exceptionally effective due to it's design. I can tell you for a fact the cooler design is much different on the retail GTX280's. It also appeared that NVIDIA is smart with their thermal paste application and doesn't overdo it (unlike it's partners). The only thing I was somewhat surprised about is that NVIDIA decided to go with the cheaper Hynix video memory manufacturer. They aren't known to be the most exceptional RAM producers but this video memory did seen a little better than I expected.
At this point, the procedure was reversed and the card was reassembled and prepped for tomorrow night's testing.

Conclusion
When I first started to test the video card with 3DMark Vantage, I have noticed an unusually low score compare to what regular GTX280's were getting, so I decided to go and test Crysis afterwords. Upon testing I had also found that the results were unusually low for a GTX280, almost on par with a 9800GT. Well as you would expect, I seemed a bit puzzled and confused at first and thought to myself, is this really all the card could handle? No way. So I decided to think of several reason for my terribly low performance and I had come to the conclusion that either the updated drivers lacked proper support for earlier revisions of this card (since they were never release) or, the BIOS might be some kind of primitive "debugging BIOS" used in NVIDIA labs for testing and diagnosing purposes. So I decided to give it a shot and find the latest NVIDIA-based GTX280 BIOS on MVKTech.net (http://www.mvktech.net/). When I first came up with the idea I thought, there is no way the hardware would be similar enough to make this work, but I decided to try it anyways and see if it might just work and if it didn't I would just reflash back to the original. So I saved a copy of the original BIOS (since I knew there was no where I could find it online if anything went wrong) and decided to proceed with the flash. And surely enough, upon reboot, I was ecstatic to see that EVGA splash screen.
Even though I did flash the BIOS, I decided to use NiBitor to compare the two BIOS's before further testing. And from what I saw, aside from clocks and voltages, there wasn't a single thing different that would make the card operate any different. Regardless of my findings I decided to test it anyways and see if there might be some miracle and it actually performs properly. As soon as that Crysis benchmark loaded and started going I noticed a drastic difference in FPS. Everything start moving so swiftly and smoothly. I decided to wait for the results before making any assumptions and surely enough, as soon as the results came up, I saw a near 50% increase in performance all around. At this point, I decided to flash back to the previous BIOS and start testing and recording my results. Soon as I was finished I reflashed back to the newer BIOS and test again to compare my findings. After confirming the vast performance increase I decided to follow it up with overclocking on both BIOS's to see if one overclocked better than the other as well as testing the temperatures.
Soon as I completed all my tests I was able to find that my performance was far greater. The overclocking potential of the older BIOS was quite limited due to the fact that the voltages on the original BIOS were lower which in effect limited the stability at higher clocks. And upon all my testing, I had decided to stay with updated BIOS due to the fact that, even with overclocked clocks, the original BIOS couldn't achieve anywhere near the performance of the upgraded BIOS. To sum up this very interesting review, I can honestly say, this card is unlike the likes of which I've ever seen before. It is amazingly well built with very solid cooling and performs (on the new BIOS) like a champion. In effect I can confirm that this risky purchase was worth every penny and will definitely go down as one of the luckiest purchases I've ever made.
