No cooler for your processor?? 

What is your CPU and GPU temperatures? Also, what PSU u using?

guys,R9 280X toxic,vapour-x vs windforce,which one would be a better bang for buck?

With that said while this isn’t necessarily a head-to-head article between the 280X Toxic and the Asus 280X DirectCU II TOP, it’s a logical comparison we have to make given the fact that both are factory overclocked 280X cards shooting for strong out of the box performance.

For gaming workloads the 280X Toxic cleanly and clearly beats the Asus card here by a meaningful performance amount.

However Asus is absolutely a spoiler here due to their aggressive pricing and their very quiet cooler. Their 280X DCUII TOP can’t match the Toxic, but it’s $40 cheaper and over 5dB quieter.

Consequently if all you want is the fastest 280X on the market then Sapphire’s 280X Toxic is clearly the card to get, otherwise the Asus card is worth a consideration for its better price/performance ratio and cooling performance.

As is almost always the case for factory overclocked cards there is a price to pay for the very fastest card, both in literal cost and in power and acoustics.

Silicone lottery mang, different chip different headroom, doesn't matter Toxic/Vapor-X/Dual-X/Ice-Q/WForce/TFrozr/Matrix.

TOXIC = when you don't want to play the overclock lottery/game. Already tested to run stable Factory OC-speed

VAPOR-X = vapor-chamber, better heat transfer, slightly lower temps, useful in our weather or you don't have AC in your room/workstation

DUAL-X = vanilla, want to OC yourself, wants sauna in your case (if your case is not well ventilated may make your motherboard components & CPU hotter = lower OC, instability, etc.)

I wish I had to buy my new PC this year instead of last year T.T Would have been able to get the 280X but now stuck with 7950 T.T 280X looks so snazzzzzzzy

I read some review, they said Vapor-X one already overclocked, can't push any much further.

VaporX uses 2x 8pin rather than 6pin+8pin.

bro, can elaborate more. you word to powderful

Buy now or wait for other brand to come in?

as said. OC is all about Lottery. sometimes you get golden, some lemon and some normal chip.
in my case i able to push another 150mhz into core clock on top of that fc oc'ed vapor-x.

i wonder, since the new r9-280x is basically the same 7970, what different is there if i push my 7970 clock to match with r-280x clock?
I juz notice the r-280x vapor-x core clock is juz 50mhz incremental as 7970 vapor-x? 

If not mistaken, the max boost clock for the new 280X Vapor-X's max boost clock is at 1020 MHz, slower then even 7970 GHz Vapor-X's boost clock of 1050 MHz. The only one that really runs higher than the regular 7970 GHz is only 280X Toxic (1150 MHz).

the price for 260X vs 7790 = SIGH!!!!

I guess I go for 7790 -.-
