Ok, I have another question about the 6000 series, I have a 5770 at the moment, so should I buy another 5770 and Crossfire or just buy 1 6870?

the second PCI-E 2.0 port is only x4 speed and the first port is x16, wont the second port slow down the Crossfire process?[QUOTE="oOiRuL3zOo"][QUOTE="SoraX64"]How's this look?hartsickdiscipl
It depends on what kind of GPUs you put in that rig. This article shows that an x4 slot only slows down a 5870 by 5 to 8%.

I think one of these budget Crossfire mobos with the 2nd x4 slot would be great for a pair of 6850's.
http://www.ebuyer.com/product/196392 That looks really good, around the same price and the second port is 8x and not 4xyea thats what I was thinking, but are they also worth the money because all I would like really is to use it to put my OS on so it would make my desktop and boot up alot faster and of course to put the odd game on maybe.Drives are so fast now I wouldn't worry about it.
If you have the cash, and really want the performance, get an SSD.

Wow, think that explained everything thanks, would I be able to put my 160GB 7200rpm and my 1TB 7200rpm HDD's into RAID? or do they have all the same specs e.g. memory, rpm, cache etc.?[QUOTE="oOiRuL3zOo"][QUOTE="NailedGR"]
It is pretty easy.
It is at least 2x as expensive to set up than a single harddrive though, because you need at least 2.
Here is a video of 24 SSD's working in a raid:

Every raid array I've seen all the drive were identical.
Would it be worth it to buy myself another 1TB HDD then? it only cost £45 which isn't bad but is it worth the time and money?
I wanna make sure we're on the same page, I mean x4 as in the speed and not the size of the slot, and yes I was going to Crossfire 2 6870's but some told me to wait for the 6890 just incase.[QUOTE="oOiRuL3zOo"][QUOTE="hartsickdiscipl"]

I wouldn't crossfire 2 cards that are any faster than a 6850 in a board with an x4 slot as the secondary. Yes, I know the 2nd PCI-E slot is a full-length slot, but running at x4 speed. My motherboard has the same. Since the 6870 is only a bit slower than a 5870, and we can see the 5870 losing a bit of performance over the x4 bus, I'd have to assume that the 6870 would lose a similar percentage of performance. The 6850 seems to fall right on the line where you wouldn't lose much performance. That's just my interpretation of the numbers. If I were going to buy a pair of 6870's ($240 US each), I'd probably get a motherboard that would run both cards at either x8 or x16.
Once again, that's just what I would do. I'm sure the x4 slot won't be a massive bottleneck to the 6870's.
Woops sorry I meant 6970, and yea I see what you mean. But if I were to just have one 6870 and not crossfire 2 of them should I buy it or still get One/two 6850's?Wow, think that explained everything thanks, would I be able to put my 160GB 7200rpm and my 1TB 7200rpm HDD's into RAID? or do they have all the same specs e.g. memory, rpm, cache etc.?It is pretty easy.

Sounds pretty nifty, is it easy to set up?Raid stands for
Rapid Array of Inexpensive Disks
Basically there are different RAID types, 0, 1, 1+0, 5, JBOD
It is different ways of setting up harddrives.
Most servers are set up using RAID 5.
I forget which one, but either 1 or 0 is mirror and that makes an exact copy of what disk you already have and then the one that isn't mirroring creates 1 disk that works faster out of 2 disks.

Thanks :).
