You will be fine with 1 PCI-E 16x don't worry

Two PCIe x16 slots is not going to do you any good. Crossfired 5870s are so much overkill that it'll probably make any CPU on the market into a bottleneck. I don't see the point of it unless you're trying to play games on a Jumbotron.

For that matter, most of the time, crossfiring sounds like a good idea at first, but then by the time you get to the point where you'd actually do it, there's a single card that can do a better job for about the same price.

:pfff: 

You do know that 1Ghz QDR (Quad Data Rate) GDDR5 runs at an effective 4Ghz, right?
The memory between both your examples runs at exactly the same speed.

Sapphire is a great brand and I would not hesitate to recommend them.

-Longer warranty, YES.
-Faster clocks, NO, unless you buy the factory overclocked ones which are more expensive that you can easily do yourself through the ATI CCC anyways.
-Sometimes they list the actual memory clocks, not the quad rate, which would be 1GHz x 4 = 4GHz. BTW he bought a 5870 not a 5850
-Stop the nonsense.

What are you currently running right now? A5870 will do you well for a while depending on what resolution you are running. You won't need another PCI-E x16 slot unless you plan to do crossfire. However, if you are upgrading for other reasons, it isn't a bad idea to plan ahead.

Well, from what I've seen, the GPU will still be the bottleneck at higher resolutions. The thing is, with a single 5870, the GPU is almost always the bottleneck, when Xfired, it changes back and forth with an i7 as the cpu.

At any given time, there is almost always a bottleneck, don't get overly hung up on that.

Anyways, check these benchmarks. They show core2 duos, amd 965 and i7 at different overclock settings.

You'll see that even with CF 5870's, at 1920x1200 resolution, many games gain nothing from an OC'ed i7, meaning the game is still GPU bound. http://www.xbitlabs.com/articles/video/display/radeon-h...

Interesting. That pretty definitely shows the point where the 5870 hits the wall. A little earlier than I would've thought -- although I still maintain that for most real-life purposes, crossfired 5870s is waaay overkilling it.

Anyway ... yeah, it's pretty unavoidable that one or the other is going to be a "bottleneck" of some sort (just by definition), but in this guy's case, it sounds like the bottleneck is so high up there that it's pretty non-limiting and I personally wouldn't find it worth spending an extra $150-$200 on a motherboard and $400 on a second video card to fix it. So I guess my general bottleneck statement was out-of-date, but I just wouldn't spend all that money. You could have a hell of a night with that instead.

I was suprised it was that high too and is also why I don't OC my i7 very high and backed it off from what I started at. The good news is that I shouldn't have to upgrade my motherboard and CPU for quite a while, which was my main intent when I built this system. I'd likely just end up upgrading video cards for a while.

Processor: Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz (4 CPUs), ~2.5GHz

and the motherboard seems recent, but it only includes 1 pci-e x 16 slot and a couple x 8 slots. I thinkt here's 1 or 2 pci slots too.

I voided the order for the 5870, but re-ordered the sapphire 5850 and kept the psu. the psu is too good to let go. the shipment will be here tomorrow! I ordered the 5770 and voided it, but it came anyways. it's getting returned for a refund, but i was able to receive the shipment a day later. they must have warehouses nearby.

That will run a 5850 just fine, no need to upgrade unless you have some money burning a whole in your pocket. You can always overclock the Q8300 and get a little more performance out of it.

theres many guides all over the internet. Do it slow and steady and always check your temperatures. Some vendors and makers such as gigybite and asus put their own OC'ing tools built into the motherboard, but essentially the main things you need to do is to

Watch the temperatures closely
Good Ventilation and cooling
Watch your voltage
Have enough juice in your PSU

stock fans can manage 3.0--3.4ish easily on a well cooled case

And when it comes to overclocked cards, sapphire usually puts out some of the best Ati cards. Example the 4890 Toxic and 4890 Atomic(which i believe was the fastest 4890 made) Give it a few months and there should be a toxic/atomic versions of the 5870. And no im not a sapphire fanboy, i like alot of card companies Sapphire/HIS/Asus/XFX

It's a hobby. Hobbies are fun. Granted I OCed my 5870 and didn't get much improvement because I guess they are pretty optimized, but the 5850 seems to gain alot form going to 5870 clocks from it's own stock settings.

yea when the cards in your case and the decals are facing down how often are you going to look at the card itself? Are you going to take it out all the time to look at the decals on the card. And those decals arent going to make it perform any better.


And Sapphire's 2 year warranty is just fine, in 2 years time it will be time for a new card anyway.
And XFX 5870 out of the box has a 1 year warranty, and if you register within 30 days of purchase on there site, the warranty lasts for " the duration of your life"

Also, other than the sticker, both cards look exactly the same.
They use the same PCB, components and cooler.
If the stickers where removed from both cards, you would never be able to tell them apart.

Actually I believe Sapphire sells far more ATI video cards than XFX does. XFX just got into the ATI market about a year ago.
