Summer Upgrade

post #1 of 26
Thread Starter 
With summer being right around the corner, I feel that my rig is beginning to become a bit "outdated". With a great summer job approaching with great summer money, I see no other responsible alternatives than to spend money on computer goodies! So, this is what I currently am running(Sig Rig is current):

Mobo: Crosshair V Formula
CPU: AMD 8120 Overclocked to 4.2ghz
GPU: Radeon HD 7970
RAM: 16gm Corsair Vengeance DDR3 1866
PSU: Corsair 750
Cooling: Corsair H80

I am currently running my LG 48in LED TV as my monitor but plan on grabbing up one of those amazing Ben-Q G-Sync monitors when they hit the market. My current dilemma is that I dont want to spend an OUTRAGEOUS amount of money on a new MOBO+CPU, just upgrade the current processor(Maybe to an 8350?) and am considering snatching up an additional 7970 off of fleabay for under $300. I know I am most likely going to have to upgrade my PSU(to an 850 maybe?) to support the 8350 as well as the additional GPU, and upgrade my cooling to a H100i or one of those pretty H105i's. So, should I keep the 7970 and grab another to crossfire? Or just snatch up an r9 290x and call it a day. Keep in mind, this is mainly a gaming rig and would like to run games wonderfully on the Ben-Q.

Oh and I currently am running onboard sound from the Mobo, which I know is just wrong, and will be moving into an apartment soon. So I have considered some great headphones(Maybe some ATH AD700's?) and maybe a Schiit Magni and Modi stack? but honestly dont know the first thing when it comes to making things sound good. Any help would be appreciated on that topic but that may be a question for the sound forums.

Thanks forum!

8350 is a good chip, and with an H105 you may be able to hit 5.0 with it! As for the GPU I would get a second 7970, AMD have largely sorted their crossfire problems so no reason to worry about microstutter anymore. In terms of performance xfire 7970's will absolutely chew through anything you throw at it unless you are trying to game at 4k. As for running onboard sound I do it too an haven't had any issues. You may run into some Audiophiles here who can tell the difference between onboard audio and a good soundcard but I can't. Sound cards are a waste of money to me. Same goes for headphones, I'm using a set of IPhone ear buds as a headset and I have no complaints. Good luck and take pics!

Does anyone have a comparison between dual 7970's and 1 290X? Any other suggestions?

crossfired 7900s are faster than any single highend gpu atm, especially when oc'ed.

here is a 7950/7970 crossfired at stock clocks . . .

http://www.3dmark.com/3dm11/6233890

have to oc my 290 to 1100 to beat them (stock 947) . . .

http://www.3dmark.com/3dm11/8206822

my i7 @ 4.5 struggled a bit with the 7900s but with the 290 at stock - just perfect. i can even turn off HT in BF4 and C3 maxed out using 1080.

edit: actually i set my i7 to stock and HT off in BF4 but with mantle.

Thank you. Do you feel that an 850w PSU will suffice? Or could i possibly run 2 7970s OCed in Crossfire & a 8350 OCed with my current 750w PSU?

Also, I currently and running a single OCZ Vertex 2 60gb SSD as my OS HD. I have heard nothing but horrible things about OCZ's and the Vertex line, unfortunately months after i bought it. Should I go ahead and pick up a different SSD to run the OS on? If so, what are some of the best out there. All i would need is 60gb for OS. I would hate for the Vertex2 to fail like so many others have.

Enthusiast? oc the cpu but not the gpus.

with regard to the ssd, just image it to a hdd. so, if it fails . . . just swap. my hdds are imaged. i use the free version of EaseUS Partition Master Home edition.

I use its Clone Disc Wizard.

Yes the PSU is the Enthusiast model. I have heard its difficult to get stable clocks on Crossfire. If I decided to OC them, I would need a 850w PSU then correct?

to be safe . . . yes, 850W will work. a cpu oc is a must. those 7900 crossfired are a beast. they'll need a fast cpu.

Seems to me like if you're going to have to spend $200 for the FX-8350, and $100+ for a new PSU, and $100 for an H100i, then you're into this for $400 to be able to take advantage of the new CPU and GPU.

By switching platforms now, you will reduce your CPU power consumption about 150W compared to an OCed FX-8350, which saves you the bother of upgrading the PSU and HSF. That $200 saved is enough to get into an i5-4670K or even perhaps i7-4770K (when combined with the $200 you were going to have to spend on the FX-8350 anyway), either of which are substantially better for driving a high end SLI/CFX GPU configuration.


Some technical jargon to think about:

A Haswell core, has 8 execution ports and supports up to 4 instructions per cycle.
A PileDriver module, has 8 execution ports split across 2 cores, and supports up to 4 instructions per cycle, but execution is limited to a maximum 66% of that when there is only 1 thread running on the module.

A Haswell core has access to similar instruction execution resources as TWO PD cores combined, and the haswell core is strapped to a more sophisticated memory controller and faster, lower latency caching and an overall architecture that has been refined to have lower throughput penalties for execution prefixes, misalignment's, and branch mis-predictions.

The result of all of this is about 80% higher IPC on a haswell core vs a pile-driver module when compared 1 thread per core vs 1 thread per module. This performance differential has the most significant effect on real-time workloads like gaming, especially on holding up minimum FPS in compute intensive situations (high unit count).

If I were in your position and concerned primarily with performance for the money, about to drop $400+ for an FX-8350+HSF+PSU upgrade, I would buy an i5-4670K/4770K + MOBO instead, and just use the PSU/HSF you've already got. The reduced dissipation of the haswell effectively pays for your motherboard in this upgrade.

Two 7970 will destroy a single 290x but use a lot of power and heat. A 290x will max out everything, and everything coming out and produce far less heat and power draw than two 7970's.

I would go with a 290x+ 8350. Clock per clock piledriver is faster than bulldozer. A 8350 can reach much higher OC too.
