Difference between matrix and sapphire is much higher here in my country, matrix is like 330€, while sapphire is 260€.
Probably will go with gigabyte (i like that triple fan) for 270€.
How much is R9 280X Toxic?

And they do not clock higher, especially when you put into context the high amount of volts they are set at, 1.25v. Yea, ugh do you think that's enough volts to give ppl the false impression that it clocks well?


If I had to choose one, it would prolly be the MSI, since that uses MSI's revised version of the reference pcb and it follows it pretty closely. Well, save for the retro brown pcb.

In my experience, MSI's poop-brown revised "reference" PCB is just as bad as all the other AIB boards. I tried 2 of them and both OC'd very poorly (barely reached 1150Mhz, in which case you're better buying a Toxic). Despite both being sub-70 ASIC cores, neither responded well to any voltage increases, which is the opposite of what you'd expect from a reference card with an ASIC in the 60s-70s, which makes me believe the problem lies in the power delivery of the PCB. The Matrix PCB may not be great, but I really don't see the MSI reference-knockoff being any better.

Also, ALL Ghz Edition 7970s were set to 1.256, not just the Matrix, and it seems most of the 280X's are as well. It was just the spec demanded by AMD. That high voltage is just there to allow AMD to get away with selling lower-quality silicon and have less cores that end up failing QA, but that doesn't mean the core NEEDS 1.256 to reach 1050Mhz. Some Ghz Edition 7970s did 1200 on that 1.256 or even undervolted (although that was rare). At least the Matrix makes an attempt at improving power delivery. 20 power phases and DIGI+ VRM isn't exactly proven to help with stabilizing high OC's but it's better than nothing. I've heard more reports of 1200+ overclocks from the Matrix and MSI Lightning than I ever heard about good OCs from custom PCBs with standard power delivery.

One last thing - people may hate GPU Tweak, but as far as I know, it is still the only OC software that has any control over Load-Line Calibration (Vdroop), which is pretty significant.

Pretty sure AMD said there will be no reference 280Xs, ever. Regardless, it is still possible to buy reference 7970s. Diamond is still selling them directly (although at $399 still) and Sapphire is selling a reference at $345 after MIR on Newegg, and there appears to be plenty left in stock.

Sapphire reference "R9 280X": http://www.newegg.com/Product/Product.aspx?Item=N82E16814102961
Diamond reference "R9 280X": http://www.diamondmm.com/7970pe53g-diamond-amd-radeon-video-graphics-card.html

I was gonna carefully pick out points to reply but there's a lot of misinformation and false assumptions so I'm just gonna reply in general.


OC is luck. Just because your chips suck, that doesn't mean the voltage regulators are weak. You probably did not know the initial 1600mhz world records were made on the stock pcb. Yea, the stock one that I use to hit nearly 1400mhz.

The point of mentioning the 1.25v is that it gives a FALSE IMPRESSION of overclocking prowess. That's why 1.25v is used doh, so it can hit 1150mhz or whatever. Fyi, all my reference cards can hit 1150 at the stock voltage on the stock cooler. That's neither here nor there and I'm not out there preaching that gospel to anyone. Also, by the time you actually tap into the VR of the Matrix, you would need extreme cooling and have hit past 1500mhz and beyond. That is the positive point for the Matrix and Lightnings, however most just go for the Lightning since you don't have to deal with the crap that is gputweak.

Btw, I didn't ask you for a refresher on reference cards. rolleyes.gif You're probably ignoring the fact that I'm the one who verified the card you bought from Unoe can hit gold clocks. You know he couldn't hit those clocks on his own right, lol?

According to KitGuru review, Toxic beats Matrix Platinum in benchmarks and temperature:
www.kitguru.net/components/graphic-cards/zardon/sapphire-r9-280x-toxic-edition-oc-3gb-review/18/
And it has received good reviews by others as well.

I recommend the toxic over Matrix(Platinum or not). If you want other recommendations, VaporX and Asus Top looks like decent cards as well.

Well, it's just 1-2 fps, isn't it? I don't think it is worth those 40€.

£260-£280

I'm paying £285 per card. (want to give some business to my local small PC shop, so many shops closed up in my town, so like to spend a bit extra to help my local economy.)

According to TPU the temperature of that card is to high:

hmmm, looks like i got a lot of toxic recommendations, a MSI one from the 'gpu god'?  and a couple others

 

i think i'll go with the Toxic, unless you think otherwise, let your voice be heard! :P
