Hello Tek,
I found a great deal for two slightly used Sapphires R9 280Xs...(150€ each, still on warranty for another ~18 months)
I did some research and found out that there are two models on Sapphire's site. One has the UEFI in it's name, the other doesn't. What does this mean?
What is the difference between the two?
The ones I'm interested:

The other listed on Sapphire's site:

I have an old MSI Eclipse with a 1st Gen i7, will the UEFI variety work on that one? I thought I should ask first before I go buy something that wont work on my rig. These two were part of an 8 (2 systems, 4 GPU each) GPU BTC mining rig. The guy is a friend, didn't overclock anything, had them running 24/7 for 2 months mining until he got ASICs and now he wants to get rid of the last two. Sound like a good deal, doesn't it?
Thanks!
PS
Sorry for mah poor grammar... I'm Greek... I don't even pay attention to Greek grammar... :p
The cards have slightly different clock speeds, yours is 1050 mhz boost vs 1020. It might be that one of the cards has an older bios version...who knows. Anyways, the cards should work normally in you system. 150 euro for a low end 280x sounds like an o.k. ebay used priced, so get them if you want. Mining bitcoins for 2 months might have diminished the longevety of the cards a little, so make sure to find out who has to send in the cards in case you need to use the warrenty ( might be the original buyer, might have to be registered in a certain time frame).
Wow... are these Sapphire 280x low-end? Which 280X is considered a high-end card?
They're not "low-end" cards, they are just normal R9-280X's. Basically means they have a few less features and aren't as receptive to overclocking as some of the more expensive variants. They will still perform just as good and any other stock 280X +/-.
IMO it doesn't make sense to buy the more expensive versions because at that point you're getting close to the price of the next higher range of cards (290 non-X) which will yield significantly better performance that no overclocked and strung out 280X could ever touch.
I would consider these 280X's a good buy (either one). Sapphire is one of the best AMD GPU providers known to deliver great performing cards with excellent reliability.
Oh, ok. I was worried there for a minute. I'm not interested in overclocking it, or any other part on my computer for that matter. So my initial worry was/is the UEFI in the title, which doesn't mean anything compatibility-wise with my motherboard (MSI Eclipse SLI).
