Is this a good 7970 ghz (possible crossfire) gaming desktop?

People say 7970 ghz for a single 1920 x 1080/1200 monitor is an overkill. However, I really love 60 fps or at least 45+ stable fps at ultra setting (including AA). I'm not sure whether to get 2 7970 ghzs or 1.

I wanna know if there's anything that I'm missing, whether they are all compatible to one another, and better option at similar price range.


Case: COOLER MASTER HAF X Full Tower Computer Case

Power supply: XION AXP-1000K14XE 1000W ATX 80+ Bronze Modular Power Supply

Motherboard: MSI Z77A-GD65 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

RAM: CORSAIR Vengeance 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M1A1600C10 (Came with the motherboard :D )

CPU: Intel Core i7-3820 Quad-Core Processor 3.6 GHz 10 MB Cache LGA 2011

GPU: Vapor-X 7970 ghz edition (cfx?)

HDD: Western Digital Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache Internal Desktop Hard Drive Bulk/OEM - WD1002FAEX

Optical drive: ASUS Black 12X BD-ROM 16X DVD-ROM 48X CD-ROM SATA Internal Blu-ray Drive Model BC-12B1ST/BLK/B/AS - OEM

Liquid cooling: CORSAIR Hydro Series H90 Water Cooler

Wireless card (will connect directly), sound card and SSD are not a priority right now.


2 free games: Crysis 3, Bioshock: Infinite (Although I wanted to go custom built at first to get 6 free games, they don't have 7970 ghz edition :(  )

If I buy 2 cards, I will sell the extra voucher for 80-90 to buy Tomb Raider, Far Cry 3/possibly Hitman: Absolution (on sale). Already played Sleeping Dogs.

It all comes down to $1500 with 1 7970 ghz and $2000 with 2 excluding monitor that I need to buy.

if you play on single monitor go get the 1 if you play on triple monitor pick the Crossfire!if you get one on the triple monitor you may want to downgrade the settings to high so not to be laggy!

Thanks for the reply, but what about other questions?

You don't need 2 7970 to play 3 monitors. 1 will do. Anyways, get an H77 motherboard, not a Z77 as that CPU is not unlocked. Also, no point of liquid cooling if no OCing.

I thought Z77 is the only thing that's crossfire-capable and allows overclocking.

I will definitely overclock and go dual, just a matter of when (now vs. Q4, when 8000 series is rumored to come out).

WHAT CAN I USE IN PLACE OF LIQUID COOLING (not gonna OC CPU in quite a bit), then..?

Anything else that I'm missing?

Addressing the more important point here that you havent raised. Do not get that PSU. I can't stress enough how much you want to get a PSU from a quality manufacturer such as Antec, Seasonic, PC P&C, XFX etc.

Also 1000w is overkill even for dual cards. 750 or an 850w will be sufficient

Other things i've just noticed.

If this is just for gaming, get an i5 3570k, i7 is not needed at all. You will get very small performance gain for a big price with i7.

In a build this expensive you should be considering getting an SSD.

Water cooling is a waste of money unless it's a custom loop. Closed loop systems can be equalled in cooling ability by a decent air cooler that's less hassle to install and cheaper to boot.

Wow, I didn't know about that...Will have to cancel/return some of the things I bought (Blame my itchy trigger finger).

So instead of i7, i5 3570k = $70 saved

No OC for now, no liquid cooler = $100 saved

Still no SSD for now (Feel like it's luxury's luxury...If this HDD is slower in loading than expected, then maybe <My laptop had a HHD-SSD-hybrid, and it loaded pretty fast) :I )

CORSAIR HX Series HX850 850W Gold Certified = $20-30 more



Saved $150!



Still not sure whether I should get one or two GPU. I just feel 40-50 fps attainable (even with with an overclock, not quite over 60 <I assume>) in games like Crysis 3 is a bit iffy after seeing my friend's 690 running all games buttery smooth over 60+ ghz in 120ghz 1200p monitor. (Yes, I was jealous :/ )

Any other components that I forgot? I'm a desktop newbie, if you haven't noticed already

Don't think of an SSD as a luxury. After you've got a respectable processor, 8GB memory, and a gaming-grade graphics card, an SSD will have a bigger impact on your perception of your computer's performance than any other possible upgrade.

It won't buy you faster framerates, but in pretty much every other metric, SSD is king. You'll start enjoying it from the moment you begin installing Windows, and you'll continue to enjoy it every time you open a program, copy a file, save a file, load a zone in a game, or move around a seamless open-world game. It makes a world of difference. After getting used to my SSD, I find that doing anything at all on an HDD system - even a decent one - is torture. It's like traveling back in time to 1995.

An SSD (at least 128GB) should be a standard part of any build over about $1000. At $1400 or so, go to a 256GB SSD.

Suprised no one mentioned it, but you were trying to match a Socket 2011 CPU with a Socket 1155 mobo. All good if you go 3570K.

Based on every benchmark I've ever seen you'll certainly need to use dual GPUs to run the settings your after on 3 monitors.

So here's change log, so far.

Liquid cooler -> COOLER MASTER Hyper 212 Plus

1000 w power supply -> 850 W Corsair HX850

i7 3820 -> i5 3570k

1 7970 ghz for now (If I don't like fps, will buy the 2nd)

Still saving that SSD till later.

Roughly $1400.

Anything else that I'm missing?
