http://www.newegg.com/Product/Product.aspx?Item=N82E16814127681

APPROXIMATE PURCHASE DATE: 22nd September to 7th October

USAGE FROM MOST TO LEAST IMPORTANT: Heavy Gaming such as Battlefield 3, Crysis 2 and Skyrim. I might also be doing some Folding@home depending on the GPU.

CURRENT GPU AND POWER SUPPLY: Intel HD 2000 with Greatwall 400w. 2 12v Rails
12v Rail: 17A 12vCPU: 12A

OTHER RELEVANT SYSTEM SPECS: Core i3 2100, Gigabyte H61-D2P-B3, Kingston ValueRam 1333mhz, WD 1tb HDD

BTW, I'm from Australia.

PARTS PREFERENCES: Going with Nvidia or AMD doesn't really matter.

OVERCLOCKING: Yes

SLI OR CROSSFIRE: No but will be considering it in the future.

MONITOR RESOLUTION: 1920x1080 4xAA with all settings maxed out.

ADDITIONAL COMMENTS: Due to the fact that I will be overclocking my card, could someone please recommend a card that gives better fps after overclocked. The budget is $350 maximum, cannot go over.

  1. Best answer
    You'll want to go for a 660 ti for sure of those 2 cards. I'm not sure if either site offers it yet, but it's much better than a 7870 if your budget allows. The only problem is that your PSU doesn't have the power for either card, you'll need a new PSU as well. You'll want a good quality 500w or higher PSU with at least 40 amps on the 12v Rail.
  2. The 660 Ti makes more sense in this case. The price is about the same so that's not much of a factor. Crysis 2 does favor AMD's GCN architecture but the other 2 perform better on Nvidia hardware. Also as the guy above me said, you probably want a good power supply for this upgrade. I'd recommend a good Seasonic or Corsair unit.
  3. the cpu is going to hurt you at your desired resolution in BF3 no matter the choice.
  4. Is there any benchmarks comparing the two cards at max overclock? I really want to see the numbers as I will be overclocking. Regarding my CPU bottleneck, would it still bottleneck if I increased the AA?

    Thanks
  5. Just another question, would the 660ti be more futureproof as it only has a 192 bit memory bus?
  6. http://www.digitalversus.com/graphics-card/face-off/13911-13891-versus-table.html

    Thats an OCed 7870 vs a stock 660 ti, there is no question as to which is better.

    As far as frame rates go you'll be able to get around 60 on medium settings in BF3 with AA turned on with that CPU. But if you upgrade the CPU down the road you'll be set as that GPU is plenty to max out BF3 at 1920x1080.
  7. Yes, that is an OCed 7870 but only slightly. I've read reviews where their 7870 goes up to 1.2ghz and beyond. How does that compare to a 660ti?

    I'm worried about the 192 bit memory bus as the 660ti did evidently have problems when high amounts of AA were used. Would it be "future-proof" when the latest batch of games come out?

    part of me wants to say no, but I cant vouch because no one can really tell what is going to be released in the future. the only part of the PC thats future proof is like the case. everything else will be timed.
  9. Alright, thanks.

    Which brand of the 660ti do you recommend me to buy?
  10. evga and asus are the common two choices, evga for its warranty and service, asus for its silence/cooling ratio.


    between the msi vs gigabyte, thats a choice.

    gigabyte usually has best cooling performance, at the chance that gigabyte is usually the loudest. MSI is usually the allarounder, and has access to unlocked voltage for extreme overclockers
  11. The Gigabyte card had issues with the fan rattling so that eliminates it from my choices. Is it worth to get the MSI 660ti Power Edition or save $20 dollars and get the Twin Frozr Edition. Also, the Asus 660ti DCU ii is the same price as the MSI Power Edition. Which one should I get?
  12. gpu brand nowandays have only slight differences, unless you get one that looks like a reference model(im looking at you visiointek for amd cards) I personally would rather have a MSI Twin Frozr over the Power Edition, but if its the same price as the asus dcuii, I would have probably went asus.
  13. I'd go with the 'regular' MSI http://www.newegg.com/Product/Product.aspx?Item=N82E16814127697 and OC myself. I've never had an issue with any MSI card I've used (ati or nVidia).
  14. Ok, I'm set on buying the MSI 660ti Power Edition. But just a question. My PSU has two rails, one for the CPU, the other one is for other components.
    The amp rating for the rail which is not for the CPU is 17a. Would this be enough to run a overclocked 660ti?
  15. I would heavily sugest changing the PSU 17amps is like 7770 levelish

    See my first post: "The only problem is that your PSU doesn't have the power for either card, you'll need a new PSU as well. You'll want a good quality 500w or higher PSU with at least 40 amps on the 12v Rail."

    You'll want a new PSU with the GPU. Something like http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028 would work.
  17. Ok, will upgrade my PSU. Thanks everyone for giving back quality responses.

  20. All Nvidia cards perform better on BF3. Is there any skyrim benchmarks?


  21. note that these are all gpus at reference clocks when tested. actual results will be higher.

    The 7870 does do better at 1920x1080, but on the overall scale the 660 will out preform the 7870. This is coming from an ATI fan, I'm using a 7970 right now. At the $300 price point you can't beat the 660.
