Ask the same question a while ado but it seems to have disappeared.

Well, here it goes (again). If I put R9-270 togerther with my AMD A10, will APU bottleneck the GPU. And do you recommend it?

If it helps, I'll overclock my APU just to minimize the bottleneck.

I'll gladly provide my other system specs if it's necessary.

Thanks in advance!

well, a10 5800 actually is a athlon 750K without igp..

and athlon 750k almost have same performance with Phenom II 965 BE despite lack of L3 cache..

R9 270 is 7870 with a slight GPU underclock..

well, actually, you'll experience a little bottlenecked..but just a little..85-90% of that card real performance..
and you'll still gain significant performance boost for all of your games..

but like you say, overclock will help..a lot, to minimize this bottleneck effect..

Well that is good new for me. That's 1 thing down the road. Now let's take it up a notch. Yes R9 270 is OK, how about R9 280? Is it still possible? If yes, then which is better (with the price in mind), the 280 or 270 as there is about $100 difference in price. I'm from the Philippines so every time I look for prices I always calculate the estimates in dollars so it may or may not be higher that the estimated cost.

I'm actually undecided between 4 GPU's, 2 Sapphire R9 270 and 2 Sapphire R9 280.
Since were here what do you recommend?

R9 270's

In short which is better the DUAL-X or the VAPOR-X version.

What confuses me though is the R-270 VAPOR-X version can support 4 monitors but the others only support 3? And of all the 4 Cards, the R-270 VAPOR-X has the highest Core Clock while the lowest was from R-290 DUAL-X version?

well, vapor series means premium unit from sapphire..
better cooler, higher clock, higher component quality, and more connectivity..

of course, vapor series is better..

mmm, do you want run these card is crossfire mode..?

if you run in crossfire, your system will be heavily bottlenecked..
because more cards, means more processor horse power for frame synchronizing process between 2cards (or more), and it's need very fast processor to extract the performance..

even with a single R9 280 is more than enough to play any game at the highest setting..

Yes, I'm planing to Crossfire but sometime in the future. Gotta buy new Mobo first then new processor. But for now, I'll stick to 1 card only. As you said, it is capable to play at High settings. I can system intensive games at 720p in low-med (like skyrim, crysis 3, Dishonored) in my current setup (A10-5800k only), but I want to play at 1080p. Does the R9-270X capable of playing those games at 1080p with High Settings?

After posting my previous question, I saw another version of the R9-270X & R9-280X from Sapphire which is the Toxic version. If I'm not mistaken, is it the fastest among the 3 (VAPOR, DUAL, TOXIC)? Coz I only see little price difference.

And back to my previous question. Is it ok for me to get the R9-280x istead of the R9-270x?

Get the best that you can afford today..
If you really want fast gaming performance, then get R9 280x.
yes, it'll be bootleneck..but still get nice 60+ fps in all games available at the high(est) setting..

and when you buy a pair of fast processor and good mobo in the future, you can extract all of this card power and gain more performance..

well..for sapphire
toxic>vapor>dual..
toxic is best series from sapphire..

At first, I was interested in the 7870 but when I asked the store through email, they recommended me the R9-270X DUAL and VAPOR versions. But I was thinking for the future. Might as well get the R9-280X version even if I have bottleneck right now, I'll be upgrading my mobo and CPU when I have the money.

Now that we're on that subject, what is the cheapest possible CPU + Mobo to pair with the R9-280X to get all the juice of it? Currently, I have the A10-5800k APU and MSI FM2-A55M-E33 mobo. Not sure of it but I think I'll only get a MOBO when I buy the 2nd GPU.

The multicard configuration hurts a little bit. But it's possible, component by component though.

Can I use this motherboard instead?
http://dynaquestpc.com/product/gigabyte-ga-g1-sniper-a88x/

You may (or not) see, but the store is from the Philippines so Amazon and Newegg is a no, no for me. This is the only place that i found which has the components I need. I you have the time maybe look for recommendations based from the site? Also, I might get the ANTEC GTX700 casing so might keep in mind the size of the motherboard and the GPU if it fits correctly in the case.

Also my Power Supply is Powerlogic ATX-700-W, can it support my system to the point of multi GPU? Thanks!

well, this gigabyte is a motherboard for APU processor..

if you want to pair it with fx 6300, then you have to buy 970/990FX chispet AM3+ motherboard..

of , if you want to go with intel configuration for dual setup, then you must go to z87chipset LGA1150 motherboard..
http://dynaquestpc.com/product/msi-z87-g45-gaming/



unfortunately not..
this power logic series only have continuous power around 350w..700w merely peak power..peak power mean this only can deliver 700w for at most 5 second or less..

you'll need real 600w-650w PSU to run r 280x multicard configuration..
seasonic S12ii 620w will fit on your needs..

To answer my question I went to the Sapphire Website and saw the system requirement of the R9 280X and here's what I saw:

750 Watt Power Supply is required.
1000WattPower Supply is recommended for CrossFireX™ System.

You said that 600w-650w PSU is enough. Well that's the thing that confuses me.

AMD and Nvdia usually give a higher recommendation rather than it's really need..

tweaktown already test r280x in crossfire mode..
you can read full article here => http://www.tweaktown.com/reviews/5826/msi-radeon-r9-280x-3gb-twin-frozr-oc-in-crossfire-video-card-review/index.html

with the system consist of..
5826_99_msi_radeon_r9_280x_2gb_twin_frozr_oc_in_crossfire_video_card_review.png

Please note, this system using an overclocked hexa core intel CPU..which is need around 200w to run..and you will using i5 4670k..a processor with lower power consumption..

the system during idle and full load only consume 134 watt and 562watt for total power consumption..

5826_52_msi_radeon_r9_280x_2gb_twin_frozr_oc_in_crossfire_video_card_review.png



So, with a 650 watt power supply, you'll have more more than 100w headroom to other parts..

Why you want to buy something can deliver 1000watt if you only use less than 560 watt..?

I see. Hmm good point. But if I were to use 1-2 1TB + a 500GB + a 120GB SDD, would it affect the power which the 2 GPU will be needing?

I already have the 500GB (which came with the computer) and be picking up the SSD tomorrow. But I plan on getting 1 or more 1TB HDD in the future. It'd be a waste not to use the 500GB since I don't have any other PC to put it.

well, according to this..http://www.wdc.com/global/products/specs/?driveID=927&language=1
Single harddrive will consume around 20w for read/write activity..(12v x1.78A)
So say that you'll using 3 harddrive, that's mean around 60w..

do some simple math => 560+60 = 620

well, still less than 650 w.
But for safety, maybe you want to add more wattage to your PSU..around 700 watt is most safety point for your powersupply

Thanks for the help!

I'd be getting that power supply first when I order the first batch of components then get the GPU next.

Now I have a place to ask for a quick response. When I finish my build I'll probably give some feedback and report of the performance when someone plans to build something like mine.

Thanks, thanks, and thanks again for the help.

I thought it was OK but upon checking the PSU i think I have another question. The specifications of tthis PSU http://dynaquestpc.com/product/corsair-gs700-700w-power-supply-cmpsu-700gs/
says it has 6 4-Pin Peripheral connection but the needed connection of the r9-280X TOXIC is 2 8-pin PCI Express power connector. Can it support 2 R9-280X?

Correct me if I'm wrong but if I can use 2 4-pin connection then I need at least 4 4-pin connection just to power a single R9-280X then another 4 4-pin connector for the 2nd GPU; that would be 8. Well this is only my understanding, I'm new at building a PC and did't build myself what I have been using right now. The store owner assembled it for me. But I am an easy learner and can easily understood some aspects if there are some info about it. So can you help me again?

Or do I need the PCI-E connectors for this? There are at least 2 in this PSU but is it 6 or 8? Is the 2 PCI-E enough for both GPU including others which I may connect to a PCI-E?

yes you right..this series only have 2 x 6+2-Pin connector..

you'll need 4x 6+2 pin connector to supply power to your graphic cards in crossfire mode..

well, i'm sorry for my mistake..

you'll need something like this..

seasonic 750w m12ii 750
http://dynaquestpc.com/product/seasonic-750w-m12ii-750-80plus-bronze-modular/

this one equipped with 4x 6+2 power pin..and an excellent unit.

Hmmm that one says: "Crossfire NO". Does that mean I can't have 2 cards in crossfire mode, but it CAN with SLI (maybe they prefer NVIDIA?). Their site and amazon noted that it is capable of multi-gpu, maybe for NVidia cards only?

I looked at some PSU and came across with the Corsair GS800 800w Power Supply here: http://dynaquestpc.com/product/corsair-gs800-800w-power-supply-cmpsu-800gs/
Just the 800w version of the previous PSU discussed but has 4 PCI-E connectors

But on this thread:
http://www.tomshardware.com/answers/id-1651974/corsair-gs800-psu-sufficient-power-sapphire-7970-vapor-3gb-ghz-edition-crossfire.html (although the GPU is 7970 which is the same as R9-280x)
if I understood correctly, 800w is possible but just barely so (the person who asked, [is it OP?]) decided on a 1050w. Also read along the lines that there are 2 versions of the Corsair PSU, Gaming and not. I'm not sure though but the Corsair 800w that I mentioned may not be the gaming version, but as long as Crossfire is possible and can power 2 R9-280x that's fine. If 800w is still not enough, maybe 1000w?

Edit: I think the GS in Corsair GS800 800w means gaming series (might be wrong though) but if yes, is it capable for crossfire?

that's just certification..

not more..
the fact is, that psu capable of running multi configuration from amd or nvdia..

peoples just try to estimate it..and the result is, more than actually they need..(note the sign "~")..
well, as you can see, r280x/7970 in crossfire mode just consume 560w while gaming..with a precise measurement..

like i said before, it's up to you if you want to buy something can deliver 1050watt and you only use less than 560 watt. :)

I don't want too much extra power so long as the 800w is capable enough. Link to another thread says so:
http://www.tomshardware.com/answers/id-1844869/800-watt-psu-sufficient-280x-toxic-edition-crossfire.html
Well he used the bronze version though and the one I'll be getting is the certified version i think (lower than the bronze) can it still do the deed? Is it only the power efficiency that's different or any other else?

Also, if I get the Mobo, intel i5, and the 2nd GPU, can I play new games at 1080p @ Highest setting WITHOUT any overclock? If yes then I think there will be no overclocking at that point so less power needed in the PSU which the 800w is enough?
