Will my computer support a 7970?

Hey Folks.
APPROXIMATE PURCHASE DATE: Either immediately(6970) or waiting until non-reference versions of sapphire 7970 are released

BUDGET RANGE: Money is not an issue. I am deciding between 6970 and 7970 because my psu is too weak for 7990 or 6990

USAGE FROM MOST TO LEAST IMPORTANT: Playing all games at max settings with full AA. main games. Battlefield 3, Diablo 3, Guild Wars 2, Batman AC, Skyrim

CURRENT GPU AND POWER SUPPLY: Sapphire amd hd 6870 dual fan edition. PSU: ocz modxstream pro 700W

OTHER RELEVANT SYSTEM SPECS:
amd phenom II X4 820 2.8 ghz
8 gb hyperx genesis kingston
1x500gb caviar black WD
1x500gb caviar blue WD
The motherboard is an amd 7xx series stock from dell. I dont want to upgrade it as they tied the windows keys into the damn thing via bios.
stock dell case, one 60mm exhaust fan(rear), 60mm on cpu, 80mm sucking up through psu. there is perforation in the case right beside the gpu. using non reference cards works best for this reason.

PREFERRED WEBSITE(S) FOR PARTS:
Newegg.ca If i have to shop online. There is a good store that I shop at with prices equivalent of newegg. From Canada.

PARTS PREFERENCES: only thing I will put in my computer is sapphire amd cards.

OVERCLOCKING: OC is a maybe. Cross fire is a no.

MONITOR RESOLUTION: 1920x1080 desktop, 1920x1080 gaming.

ADDITIONAL COMMENTS:If getting a 7970 would be pointless with my configuration I will get a sapphire dual fan 6970 now instead of waiting for sapphire to release the non reference 7k cards. But the new architecture of the 7k series is attractive.
Thanks.

More about will computer support 7970
  1. No problem running either cards with your system, but you're better off with a stronger CPU such as the Phenom II X4 975/980BE. These CPUs are monsters for gaming.
  2. So a different plan could be get a newer quad core and get the 6970?

    then I have a question for you. If i swap processors, is it plug and play or will I have to reinstall windows?
  3. yes you should be able to switch cpu without reinstalling windows.

    Your psu is more than enough for either card as well as either the 6990/7990.
  4. Best answer
    Your CPU is not that strong enough to render high textures and packs with good FPS, the AMD phenom II X4 9 series family are good performers, the 975/980BE particularly perform like the high end 2500K in most Situations.

    So you might not see the maximum results you're expecting with ur current CPU as you've a dell machine and OCing is not an option.

    HD 7970 is about 27% faster than HD 6970 and 10% faster than GTX 580.

    If you swap CPUs, it's plug and play no need to reinstall windows, but if you're going to change ur CPU contact Dell support first, their MOBOs sometimes have restrictions and allows only particular CPUs.

    Whether you buy a 79xx or 69xx they will run your mentioned games @ ultra 1080P.
    Your PSU will support any of the mentioned "Dual GPU Cards" even though it's a small segment PSU.
  5. ok I lied in the beginning now money is becoming an issue. I had enough to do what I wanted graphics wise. but talking about upgrading a processor is creating a dollar sign ceiling.
    So what about this configuration.
    AMD Phenom II X4 970 Deneb 3.5GHz Socket AM3 125W Quad-Core Desktop
    sapphire HD 6970 dual fan edition
    and will my 700w psu support that setup.
  6. Yes.
  7. I like this result. I dont have to wait for the 7k series to come out. and it all works out to be a little cheaper than the 7k series anyway.
    just have to get in touch with dell and make sure they didnt lock the mobo to certain cpus....
    I will go with that gpu and that approximate cpu in my final build. a thermal pad comes with the cpus that i just apply then reinstall my heat sink right?
    Ill get the gpu in the next couple days but all the stores around here that have good prices on the 9xx cpus are sold out xD so that will be awhile. will take me a day or two to get a straight answer from dell anyhow >_>"
  8. They have an online support, you just chat with an agent and it's all done.
    I don't understand your talking about the HD 7K and they are already out!, even the non reference designs have good reviews. And they are already non ref designed ones like the XFX black!

    HD 7950 is reported to come Jan 31, it's supposed to be on par with the GTX 580.
  9. And after everythings said and done you could ebay your old cpu and put that money torwards another 6970 or a ssd in the future (motherboard permitting)
  10. I dont like the reference cards due to cleaning difficulty. innards get dusty and its hard to get them apart sometimes. And I use only sapphire amd cards just out of experience and personal preference. Also the 7970 reference comes in at a whopping 275mm Length where as my case space for the card is limited to just over 260. I would put pressure on the card with the power connecters. And yeah i know they are already out man, im just saying that if im getting a new gpu AND a new cpu that the 6970 is more doable financially.

    regardless I have a better idea of where im going now. Thanks to all for answers and comments/opinions.

    Thread solved.

    if a 980be is a moster what is a 2500k/2600k?

    the top amd solution still will hold back a 7970 and to a lesser degree a 6970 in new games like battlefield.

    you should really consider an intel system with either a 7970 or 6970 it would cost about more now but amd systems are really a dead end.

    oh and here is how much performance you loose with the best amd cpu's
    http://www.guru3d.com/article/radeon-hd-7970-cpu-scaling-performance-review/5
  12. i think buying a new processor would not cause a lot of differences because you already got a quad core processor. Please refer to this link http://www.guru3d.com/article/radeon-hd-7970-cpu-scaling-performance-review

    You should show him graphs that shows how much performance he losses in terms of FPS at the resolution he is using. As you can see from the conclusion of the same article you posted he does not need an Intel processor for gaming a quad core Phenom II will do just fine.
  14. I would replace that OCZ piece of crap psu right away, they are junk and if you value your components then id replace it with a quality 600w or so unit unit
  15. you really think the extra cache on the 955 and up is going to make a difference!? I doubt it and im just coming from an oc'ed 955 I also had a backup rig with an athlon II X4 and could not tell a difference fps wise in gaming at stock speeds...

    really for the OP I think a 6970 is overkill given their current CPU and maybe the op should shoot for a gtx 560/ 6870 level of gpu, to me that would be better paired parts
  16. Snag and mod an HD69502GB dualBIOS reference design.

  17. @jjb8675609
    +1 for the PSU idea, but no need to swap the PSU, the guy is just running a single GPU the OCZ ModXstream and StealXstream are very crappy in SLI/CF Systems.

    @cbrunnem
    With all respect, i hate people turn the thread into AMD vs Intel, the OP is just better with that CPU i mentioned and if you understand what you said, you wouldn't provide that link.

    @jjb867
    Yes the extra L3 cache help improve the gaming performance, And again you mentioned before you had the 955 with the CF/SLI setup not a single GPU and you know that AMD CPUs are not powerful enough to cope up with high end GPUs in even if i see the difference is reasonable considering AMD is behind Intel by gens.
  18. @cbrunnem
    Listen i didn't want to hijack the thread but no problem for clarifying some concepts.

    The 980 BE is a monster CPU for gaming in the AMD side, the per core performance of the Deneb beats the per core of thuban and Zambezi, the Phenom II BE is 2 generations behind Intel's SB K series. But as a Quad core CPU it's doing great in all GPU intensive games, and in most CPU intensive games the difference is countable between the 2500K and the 980/975BE.
    Let's have a look from your link

    970 BE is 59 FPS, I7 2600K @ 5 GHz 61 FPS

    BF3, the image speaks for itself

    Only the BE failed by countable FPS which makes no performance gain at all

    From techspot, look at 1080P results




    Do you need to see more ?
    The bottom line is that the 975BE which is $145 is doing great compared to other Intel CPUs which is priced $225 and $300 specially in the gaming field
  19. A phenom 2 BE cpu is still pretty amazing for gaming. I'd say get the 7950 when it launches as its going to be as powerful as a 580 at stock and will OC great judging from the 7970 benches. if it doesn't perform too well it would probably lower the price of the other gpus.

    the 7950 is probably launching jan 31.

    the graph you show of bf3 is utter useless. show me a graph of cpus during multiplayer with 64 players playing and then you will have a real indication of that game. no one barely spends any time in single player mode but there are no benches of online.

    thats two of the most popular games this year that intel has a big lead in.
  21. skyrim is only 1 game and it just means you turn down the settings a bit. It is also the only game where the 970 falls so far off.

    The phenom x4s are plenty powerful enough to drive bf3 on high in multiplayer.

    in bf3 i would say the are powerful enough to get good fps but not max the gpu is capable of.
  23. no, bf3 the phenom can pull constant 60 fps and if you play on anything high or above the gpu will be the bottleneck.
  24. BF3 is a GPU intensive game, Skyrim is a CPU whore.

    @cbrunnem
    Fortunately Skyrim was patched to run great even on a Q6600 reported by some members here (as i don't play the game now) and before it was patched i was able to hit a constant 60 FPS with my 1055T @ 4.0 GHz & the game itself had graphics bugs and a lot of members here reported low FPS even though they got high end setups. Another review of Skyrim during CPU scaling


    what about the Online gameplay ? since the BF3 was Beta and i have seen no difference, FPS on BETA was the Same after launch nothing changed.

    im currently running a xfx 7970 blackedition on a 700 watt power supply. difference is that it is 80 plus silver which allows me to over clock both my old school i7 920 and 7970. focus on getting a good power supply and better processor before you go out and purchase a 600 dollar graphics card. (mine cost me 652 and i had to check on newegg every single day for a straight week!)
  26. the psu is fine. the 7970 only has 275 watts tpd and only draws like 192 watts when loaded. rest of the system will draw less than 200 watts loaded.

    even if you OC you'd still have plenty of headroom with 700watts.

    it is true that 700 watt is fine. 80 plus just more efficient and saves energy...
  28. his psu is already 80+

    if i set my affinity to 4 on bf3 i cant play at all. its just unplayable at the same settings. idk if that means it doesnt like hyperthreading or not but if thats true then it just goes to show bf3 online needs a quad core.
  30. nothing likes hyperthreading.
  31. esrever said:

    if it only needed two cores that wouldnt matter cause it would use the full core first. right?
  32. yes windows will put the threads on 2 real cores.

    there are games that have 2 main threads and a couple smaller threads which could be potentially put onto a virtual core which often cause a bit of performance hit while gaming.

    often disabling hyperthreading gives a slight edge in gaming but its not much, usually around 1 fps or less.

  34. Ive just upgraded from a 6970 which work well with my phenom 2 980. my 7970 isnt performing to its full! 81% usage and its diping in to the high 30's on 64 player maps so no a phenom 2 will not push a 7970 to its full. I need a bridge thats sandy i thinK!
