R9 280x Crossfire?

[horrorxpunk]

Hi guys,

It's an exciting time of year with AMD pushing out their latest and greatest batch of video cards and I nearly can't keep my legs crossed over the R9 290X benchmarks and pricing which I am waiting for the official release on this information.

So it's time for me to get a new video card yay. I currently have the ASUS GTX 680 DirectCU II TOP and I am only upgraded because video games are now demanding more video memory ( in particularly BF4s 3GB Vram recommended )

With the pricing on AMD's cards, it would be criminal to pick 780 or Titan, I'm looking at price per performance and one of the setups I am considering is R9 280x in Crossfire or single 290x and upgrading to crossfire later on and was just wondering if anybody had managed to source any benchmarks for the new cards in crossfire as I can only find benchmarks for crossfire with the 7970. Do you guys think crossfire performance will be the lesser, the same or greater than a single R9 290x. Obviously if a single 290x is £500 then it looks like 2 x 280x will be the thing to get.

Any ideas or suggestions? Physx isn't even a thing anymore for me, but is Nvidia still the way to go, do they have a new card round the corner that isn't a rehash with a massive price tag? Should I stick with AMD at least until Q4 2014 when we are looking at the new Nvidia cards.

280x = 7970 ghz, it even has the same pcb

The only change is the move to gcn 2.0, not entirely sure if that will have a big advantage over gcn 1.0.

Imo you should be looking at a pair of dirt cheap 7950/70's though, we already have an educated guess the 290x isn't going to touch a 7990 on perf, so it shouldn't be faster then 7950/70 cf either.

I found this http://www.3dmark.com/fs/960834 it's the lowest scoring of the crossfire R9 280x benchmarks overall but the graphics score is 15627, a single titan scores about 13,000 ~ this is exciting me. I can't wait until the end of the month!

I will be fitting the card with water blocks as well, so a single card will save on expense. Do you have any idea about prices for 290x, if 2 x 280x ( 7970s ) is better than Titan for £500 . Will the 290x be healthily priced at £450 ~ ? or like the 7970s which originally came out over £500? R9 280x DC II appeals more because it's a two slot card and not a triple slotter which is restricting. Again water blocks will be going on the card in a month or two but I can trust ASUS manufacturing for a reliable, long living and healthy card.

Two R280's will beat a titan and a 290x.

Two 7970's does the same and is cheaper.

Yeah if two 7970s are the way to go, I mite as well grab another 680 DCII but it's only 2GB I don't know if that's going to be enough VRAM for BF4 although I only play at 1080p, and it's a TOP so I would need to transfer the BIOS onto an DCII OC edition. Either way 780 / Titan is too much money and I'm getting £200 for my DCII TOP anyway which I'm putting towards a Seasonic PSU. Benchmarks suggest the 280x is more the equivalent to a 7970 GHz rather than a reference 7970 and I know it's same PCB. But hasn't the die or memory chips been updated in anyway? With it being a more mature PCB will it be a better overclocker? Also I'm not as familiar with flashing the BIOS on an AMD card, I hope it's just as simple
