Shaun98 :
Thanks for the very in depth explanation there! As im pretty new to PCs im having a little trouble understanding what you have mentioned. Sorry XD. You seem to know what you are talking about so could i ask you to put these in a list from best to worse for me please
AMD cards -
Sapphire AMD R9 390X Graphics Card (8 GB, OC, PCI-E, GDDR5, 512 Bit, DVI-I, HDMI) - http://www.amazon.co.uk/Sapphire-Graphics-PCI-E-GDDR5-D...
Sapphire AMD R9 390 Nitro Graphics Card (8 GB, OC, PCI-E, GDDR5, 512 Bit, DVI-I, HDMI) - http://www.amazon.co.uk/Sapphire-Nitro-Graphics-PCI-E-G...
Sapphire AMD R9 290 TRI-X OC Graphics Card (4GB, HDMI, PCI-E) - http://www.amazon.co.uk/Sapphire-TRI-X-Graphics-Card-PC...
and Nvidia cards
GTX 980
GTX 970
what would be the best purchase in your opinion?
Sorry to keep asking more questions xD Just want to make sure im getting the best hardware for my cash
As indicated above, if overclocking is something that won't keep you up worrying at night, the R9's just aren't in the discussion. Above the 280x / 380x, I just don't see AMD competing on any level. But it's hard to have this discussion w/o knowing your resolution. Since we did 1440 above, I'll use 1080-p this time and pick a brand that was reviewed by same site for each of the cards.
Here we see a number of things:
1. The reference 970 is 4% faster than the reference 390
2. The Non reference card delivers just 1% more performance
3. Two pages later we see that they were able to OC the card 7.2%
http://www.techpowerup.com/reviews/MSI/GTX_970_Gaming/27.html
From that we see that the MSI non reference 970 delivers an extra 3% and overclocked, 14% on top of that
http://www.techpowerup.com/reviews/MSI/GTX_980_Gaming/25.html
From that we see that the MSI non reference 970 delivers an extra 8% and overclocked, 15% on top of that
So the 390 / 390x can in now way compete with the 970 let alone the 980. And since the 390/390x is simply a 290/290x with a higher factory OC , it's not going to even get in the game either.
The reference 290x got 94% in the image above to the reference 970's 97%
The MSI 970 is 17.1% (133.5 / 114.0) faster than reference overclocked.
http://www.techpowerup.com/reviews/MSI/GTX_970_Gaming/30.html
The MSI 290x is 12.0% (129.8 / 115.9) faster than reference overclocked.
http://www.techpowerup.com/reviews/MSI/R9_290X_Gaming/27.html
MSI 970 = 97% reference score x 1.171 = 113.6 or about 7.9% faster than the 290x
MSI 290x = 94% reference score x 1.12 = 105.3
Now cards at different levels overclock substantially different. With AMD cards, the overclocking headroom diminishes the closer you get to the top card. With Vidia, it's the opposite, overclocking headroom increase, rather substantially, the closer you get to the top card.
Fury - X 105.05%
390x 107.12%
390 108.21%
980 Ti 131.38%
980 122.71%
970 117.11%
The 980 has been squeezed by the 980 Ti and the 970 making it the least attractive alternative.
On a performance per dollar standards, this is how they stack up. The numbers mean nothing except in relation to one another.
970 - 3.97
970 SLI - 3.48
980 - 2.63
980 SLI - 2.30
980 Ti - 2.42
980 Ti SLI - 2.11
Now the law of diminishing returns means that you will always see less of a performance increase than you will for the corresponding price increase. But the upgrade from a 970 to a 980 comes at a rather steep reduction in price / performance ration from 3.97 to 2.63 (34% drop) but the upgrade from 980 to a 980 Ti is a rather modes drop from 2.63 to 2.42 (8%).... For that reason, I just don't see the 980 as a great buy at it's current average price of $475.
On the other hand, a pair of 970s is just a 12% drop in price / performance ratio.
If you look at it from a whose buying what perspective, the last I looked, at the end of August
980 Ti - NA
980 - 0.99%
970 - 3.97%
960 - 1.60%
780 Ti - 0.39%
780 - 0.84%
770 - 1.92%
760 - 3.08%
R9 2xx - 1.14%
R7 2xx - 0.58%
R9 Fury - NA
R9 3xx - NA
R7 3xx - NA
So as you can see, there are about twice as many 970-s out there as all R7 and R9 cards combined as of the end of August. Nvidia has been slashing prices on the 980 in recent weeks to try and boost it's sales but at this point two 970s in SLI makes a lot more sense than a 980 delivering about 60% more performance (excluding games that already get over 100 fps w/ 1 card) for about a 35% increase in price.
Of the builds we are involved with, the most typical recommendations are, (in no particular order):
Single 970
Dual 970
980 Ti
380x
According to the numbers, anything above the 280x / 380x just isn't in the game. That's why the entire 2xx line had such dismal sales and why the 970 has sold 3.5 times as many cards combined (amazing in that budget cards sell much more quantities) in half the time on market. Another reason it's hard to recommend the R9 2xx series (other than the 280x) is that being 2 years old, the resale value of the card is already very low.
Since the 980 Ti came out, we haven't been involved in a 980 build. I think the price gotta drop to < $450 for sales on that card to pick up again.
