Not much. With my 6850 I was not able to play on max at 1680x1050 above 45-ish FPS (And It was OC'ed to over 6870 clocks)

It gets me something like 40-ish FPS at Max settings.

PS Dont use that site, it's a retarded way to  compare GPU's

PPS Other games run fine, but WoT is special

heh, the name of the card really is "XFX AMD Radeon HD 6870 XXX Dual Fan Edition, 1GB GDDR5" and i wonder why :Smile_blinky:

anyways, im not very good with computer speeds so what of below is most important?

Memory Bandwidth
FLOPS
pixel fill rate
texture fill rate

I don't know your budget (and even if I did, I wouldn't know how to translate it), but when I buy a GPU, I always go for the 850 tier of the latest generation, becuase it's the most ecomomical of the mid-to-high-end cards. In this case, it's the 7850.

The thing is, if you're buying a card for WoT, you have to understand that a better GPU won't necessarily yield better results. WoT uses horribly outdaded graphics technologies, and it's lack of multi-core support means that you're almost always limited by the power of your CPU, rather than your GPU.

I've just bought a 7850, and it runs this game no better than my old 5850 dd, though hopefully that'll change when the new render arrives. I did, however, get an impressive uptake in framerates when I overclocked my CPU (you can read about it here: http://forum.worldof...es-overclocking).

Basically, my advice to you is, that unless you know for a fact that your GPU is limiting your performance, don't bother upgrading (not for WoT, anyway). Though, I suppose, seeing as how the 6870 is pretty cheap, that it wouldn't really hurt you.

All of them, I would the bandwidth is a good measuring tool.

But on a serious note the 6850 and 6870 are both good cards.

You can read this for a better comparison  :Smile_Default: I enjoy reading the reviews about stuff Im going to buy, gives you a good idea what to expect. (Tems, performance, power draw etc.)

Offtopic [I was thinking, would it be possible to bench WoT by playing a replay? But replays dont seem to stress as actual gameplay./]

As far as I understand, the only importand metrics out of these four are Memory Bandwith and Texture Fill Rate.

FLOPS are more an indicator of the processor's ability to perform calculations, rather than its gaming performance.

Pixel Fill Rate is an outdated metric that hasn't mattered since the inception of DX9.

im 95% sure that my wot fps is low cause of my gpu ( amd hd 3800 ) i know its old, thats why i want to upgrade it...

7850 (220€) is a little too expensive for me  , 6870 is (160€) and the difference isnt that big

6870
memory bandwith: 134.4 GB/sec
texture fill rate : 50400 MTexels/sec

7850
memory bandwith:153.6 GB/sec
texture fill rate : 55040 MTexels/sec

id say not worth 60€

An HD 3800 series? Damn! That thing's practically medieval. You could run game better on a toaster. :Smile_trollface-3:

Well, the 6870 is a decent card, and it's relatively cheap, so it would be fine.

That being said, I personally wouldn't buy a video card in this day and age that doesn't have 2 GB memory.

I wouldnt run it at anything below 500W to be safe. My favourites are Corsair nad Seasonic.

Personally, I'd recommend buying an AMD card. Nvidia GPUs are grotesquely overpriced for their performance.

Personally, I wouldn't be using an ATI card even if I got one for free.

Catalyst are the worst Drivers that have ever been written for any kind of hardware, while nVidia Drivers, other than been really good, are upgraded frequently, giving more and more performance (For example, since Skyrim came out, the drivers have improved my FPS on that game in 40% while friends with ATI have the same FPS they had when they bought the game...).

Edit: On topic, nVidia just released Gtx 660, which is a medium price really good card (http://www.geforce.c...oem/performance)

I myself have 2X Gtx560Ti (but for Wot, it pretty much uses only half of them anyway because the limitation is the CPU) and I'm running it on max (except antialiasing) at 40+ FPS.

R you not interested in unlocking full potential of your system? :)

Actually you don't benefit in this setup. You get 0.5GB more RAM, but 64bit-system uses more memory, so you will end up more or less equal.

With 6 or more GB it's mandatory, but 4GB is... matter of taste (or money, if you already have a 32bit-windows, you won't need to pay for a new license)


Concerning PSU:
Upgrade the PSU FIRST!!
The 6870 requires a lot of ampere on 12V and your system will crah a lot in the best case. In worst case your overloded PSU will generate Voltage-Peaks or even break completely. You could end up with damaged hardware all around, incl. harddisks (and your data)
When looking for a PSU, don't go for the "watts". That doesn't tell you if the PSU delivers enough power. Instead, look for detailed information. Find the 12V-power-output (in Ampere). You need a PSU that delivers 20+ Amperes on ONE SINGLE 12V-LINE. Many high-watt-PSUs "feature" several 12V-lines with lower ampere, but that doesn't help you. Understand?

Concerning AMD/nVidia:
I am not biased in this case. I buy the card that gives me the most bang for the buck at the given moment. Catalyst-Drivers are stable and good since years now, and the get updated frequently as well. There's no "general advantage" for nVidia anymore. When looking at skyrim one could draw the conclusion that the early nVidia-drivers were flawed and needed improvement to give 40% more fps, while the catalyst was good from the start and couldn't be improved. Without further (solid) information these conclusions are all nonsense. The last cards I bought were all AMD, because in the "mid-price" range (100-150€) they have more FPS for the buck than AMD. AMD had more power in the high-price-region, but lacked proper products in the mid-price (or had only outdated GPU-designs to offer). Few years ago I bought nVidia several times, because THEY had the better cards in my price-region.
Don't let yourself get drawn into these religious, fanatic discussions about which one is good and which is evil. Just google what you can and will afford and then google these products and read their tests and reviews.

2003? I spent a couple of hours on a friend's laptop (bought this year) with an Ati card becasue the stupid Catalyst sh*t kept using the integrated intel card for some games instead of using the Ati one despite marking those games to specifically use the Ati card...

Why was the integrated card even turned on in the first place?

Ok, just to be sure I had the right price comparisons, I looked up the prices on newegg.com.

My MSI R7850 Twin Frozr III costs $220.

For the same price of $220, you can buy the MSI N560GTX-Ti Twin Frozr III.

Same manufacturer, same cooler.

Here's the comparison between the cards: http://www.gpureview...1=641&card2=678

Note that the 560GTX Ti in that comparison is actually clocked higher than the model on sale at newegg.

Conclusion: For the same price, from the same manufacturer, with the same cooler, in the mid-to-high-end range, you can get an AMD card that's from a more current generation, and roughly 15% more powerful than its nVidia counterpart.

Unless you have money to burn, buy AMD.
