I'm waiting for Ivy bridge and the 7990 to be released. I want a high end PC that will be able to run games at ultra with 4xAA on a Eyefinity set-up for a while. This is the reason why I'm asking for top quality product.

Currency: CAN$

Prefered website: newegg.ca (but open to suggestion)

CPU: Intel I5-3570k -???$-(seems like the replacement of the loved i5-2500k)


Mobo: ??? -????$- (need a top end CF gaming mobo)


GPU: 2x Radeon HD 7990 -- ???$ (Might go for Nvidia if they offer a comparable GPU in case I ever want 3d)

SSD: Corsaire 120GB -178$- (If you guys know any bether 120G SSD let me know)
http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...

HHD: 1TB 7200RPM samsung -170$- (Mostly looking for a 1TB silent and stable/fiable product. Give me suggestion)
http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...

RAM: Corsaire vengence 2x 4GB -???$-
http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...

Case:Corsair Obsidian Series 800D -300$- (I'm open to suggestion, willing to add watercooling later on)
http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

Power Supply: need suggestion on a 1000w or 1200w. Iw ant to have room for upgrades.

Screen: 3x 24 inch 1080p -???$- (Price seems to go up exponentially over 24" All I want is a good image quality with no ghostly effect and tin bazels)

Coolant: Will start with something basic but I'll move toward water cooling (I want a show room PC)

There's no motherboard on the market that will support quad Crossfire so you can cross that off, and quad 7990's will cost you quite a bit of money.

The i5-3750K isn't going to run anything new as far as technology goes. It will run on existing Z68 and P67 motherboards, which is why I'm in the minority when I say that waiting for this makes no sense to me.

Power Supply: This is where I struggle. 1 single 7970 use 214w loaded and 286w on stress test so 2x 7990 will probably be around 800 to 1000w just for the GPU alone. Also I want my PSU to have room for upgrades (will probably add more SSD later on + water cooling pump)


Again - I think this is more of a fantasy build than anything else. Realistically a 7970 is only a dual GPU on a single card (similar to the 560 2 WIN) and you can really only run 2 x Crossfire. A 1KW PSU will handle dual 7970's perfectly fine.

The Crucial M4 and Samsung 830 are far better choices than the Force 3.

Not necessarily. Only true 3-D displays are where you'll see the price increase and to me it makes no sense to have those right now as there's nothing programmed to take advantage of true 3-D monitors.

I'm not sure what you mean by "Show Room PC" but water cooling opens up tons of room for error if you don't know what you're doing. A closed block like the H100 is a bit safer than a custom block is, but even then that doesn't make much of a difference. The newer generations are a lot more energy efficient and don't require the huge heat sinks and elaborate cooling solutions they used to.

Thanks for the info but isn't 3x CF available ? I keep seeing 3x CF on tomshardware benchmark (or is it some specialy build-up) ?

And the 3x Monitor is for Eyefinity kinda why I'd go for 2x 7990 if it was possible but if only 3CF is possible I'll go with a 7970 + 7990.

As for the mobo I've been told to wait since they will provide new ports and upgraded BIOS but well I don't know realy I'm not an expert.

You can run three-way Crossfire on some GPUs but not on the 7990, it's a dual-GPU design on a single card similar to some higher-end NVIDIA cards. You'll be able to run two in Crossfire easily but you won't be able to run four.

As for the motherboard - Z68 and P67 are not changing for the most part. There may be revisions here and there to add new features and support for new hardware but for the most part you don't have to worry about that.

K so even if I have a tripple CF mobo ? 16x-16x-8x I couldn't run a 7990 + 7970 due to the GPU itself ?

For the most part it depends on the GPU itself. You have to look at the design carefully and what your motherboard allows. You'll be able to run dual in most motherboards but not all support 3-way Crossfire.

So hypothetically, does a mobo have enough bandwidth to effectively transport 2x 7990s

(which would be equivalent to 4x 7970s and even one 7990 would be overkill for any game)

Edit: read the thread again, kinda off topic question... and I realize what the OP is asking but IMO just grab a single 7970 and if it doesnt pull the monitors grab another...

You can quad cf 6990 so there should be no reason you can't with the 7990 (quad cf = 2x6990, a single 6990 is cf, a single 590 is sli). If he doesn't need the computer now, waiting for soon to be released new tech is fine but you need to put your foot down and buy when it's released. Since he's waiting, he's going to get z77 and I think trigates are somewhat of a big deal in new technology. Thunderbolt will also start coming onto pc. Prices do jump a bit after 24" and you'd probably want to get bigger than 1080p at those sizes which costs even more. If he wants a custom loop let him get it. You're right water cooling isn't necessary it's more a hobby; a show room pc. As is extreme oc if he wants to put that loop to work. It's weird you are "saving" money with an i5 if you're going to go all out then go all the way.

It's still going to be a few months til ib is released so of course this is a hypothetical thread. I think you should grab 1 7990 when you buy and when (not if) it's not enough then buy the second. http://forums.pureoverclock.com/showthread.php?14049-Ra...(quadfire)-benchmark-evaluation-3x1P Here's some benchmarks of quadfire 6990 eyefinity.

7990 = 2x 7970s on a single card, basically a xfire config
