A8 vs i3

I am planning a budget PC for gaming at medium settings and heavy web surfing and multitasking.
I am confused between the A8-3870K and i3 2100.
Both are almost equally priced.
My dilemma is that if I buy an A8 will I be able to play games at 1920*1080 resolution at medium settings without AA. Games like Crysis 1/2, Modern Warfare, Farcry, Prince of persia, NFS, Starcraft, etc. Benchmarks don't consider the full HD resolution. Why?
Or if I buy a i3 2100 and a cheaper GPU will I get a better performance?
And when is the launch of piledriver and trinity desktop launch?
I posted a similar question before, but at that time I considered FX 4100.
And what is the significance of L2 and L3 cache? i3 has less L2 cache than A8 while A8 has no L3 cache.
I am from India. Prices here differ from that of newegg, slightly higher over here.
Thanks. :sol:

  1. Your going to need a gpu for gaming at 1080p, regardless of what processor you choose.
  2. For gaming, I would definetly go for the i3-2100... and a good card.

    At 1080p, I would go HD 6870/GTX 560 graphics card or better to enjoy all the eye candy.
  3. Definitly an I3 if this computer is going to be used mostly for gaming.
  4. I would go with the i3 since it provides better gaming performance, plus in the future you can upgrade to a more powerful Sandy Bridge or Ivy Bridge CPU. I recommend getting a H77 motherboard which will allow you to install an Ivy Bridge CPU without having to worry about a BIOS upgrade.

    The Llano socket FM1 APUs are basically dead. They will be replaced by Trinity and Trinity will use socket FM2.
  5. i3 is better no doubt about it, but I would have to buy a discrete GPU to make it equivalent to A8 in terms of Graphics.
    The price of motherboard for H77 is also higher.
    I wanted to know that will I be able to play games with only the help of A8 or would I have to buy a discrete GPU at 1920*1080 resolution? If I have to buy the discrete GPU then I will go for i3 else A8.
    Thanks!

    GTX 560 is a lot powerful. I want to play games at Medium settings. No AA, etc.
    Still the A8 will not suffice?

    How many people have to answer your question before you get it? If your gaming at 1080p your going to need a GPU. PERIOD.

    I suggest an H61/H67, you can simply update the bios and run any Ivy Bridge processor and any ram up to DDR3-2200.

    Ok, got it!
    So, I think Intel seems the best option.
    Which GPU would run games at HD. Which would be the best bang for the buck?
  9. Well depends on how much you want to spend. Assuming if you were considering integrated to start with I'm guessing not much.

    Not looked extensively, but Radeon 6670 and GTX 440 are fairly cheap (I quickly found DDR3 versions here for £50, whereas 6870/560 are over £100), with the GDDR5 versions costing a little more for a bit of a performance boost. The benchmarks ive seen put the 6670 around 30 FPS in Crysis 2 1080p at high details, but I guess if you lowered those some you could get a more playable fps.

    Also cards such as the 6670 can crossfire with the A8 giving further performance. I'm not sure how much though since never looked into the APU's much, but might make the 6670+A8 better performance at that price point than the i3+anything

    Yes, I am on a tight budget here.
    Crossfire with A8 does not improve performance by much, many benchmarks show that.
    Radeon 6670 and GTX 440 seem to be better with Intel.
    Playable FPS? I guess above 30, it would be playable.
  11. OK.
    I am extending my budget. I am going with core i3 2120 and H61 MOBO.
    Please help me select a good graphic card which will be able to play games at 1920 into 1080 with at least medium to high settings in popular games.
    I have selected GTX 550ti and HD 6770. Will the HD 6750 suffice? What's the difference between 6770 and 6750.
    Also according to the specifications 6770 requires 450 watt power supply but on new-egg calculator it shows less than 350 watt when calculated. While GTX 550ti says 400 watt but the new egg calculator shows more watt requires than 6770?
    Which power supply should suffice?
    Also is it that graphic cards get damaged or something like that after 2-3 years?
  12. the 6770 is quite a bit more powerful than the 6750 and both should run on a high quality 350w power supply. The 550 ti and 6770 is about the same so and w/e one is cheaper would probably be good.

    your graphics card shouldn't get damaged by a good psu. Also be sure you have warranty.
  13. Earthwatts 380 would be perfect for you. The 6770 should be best at your range.

    Thanks.
    Please, can you send me a link of a good PSU.

    Earthwatts 380 would be perfect for you. The 6770 should be best at your range.

    But then why does AMD site states that it will require 450 watt PSU?
    And also, what should I see while selecting a PSU?
  16. You should look at a review if you want to select a PSU but generally good brands such as antec, corsair, XFX, seasonic and OCZ are pretty good. AMD likes to over suggest PSU size because many low quality PSUs can't supply the wattaged specified.
  17. Because there are so many bad PSU around. The Earthwatts isn't one of them.
  18. OK. I think Antec Earth Watts isn't available in India.
    Please help me select from the following:-
    http://www.flipkart.com/browse/computers/components/power-supply-unit-20283?sort=price_asc&layout=grid&ref=806cfda0-a5dc-4db1-97b9-fc9da1781750
  19. The HD 6770 is going to be struggling at 1080p resolution with modern games. You may be forced to go lower than med settings and no AA. Maybe even drop to a lower 16x9 resolution for smooth framerates depending on if the game is CPU or GPU intensive. Not trying to dissuade you... just want to point that out.

    Power Supply: use a calculator to get an honest idea of what you can get by with. http://www.thermaltake.outervision.com/
    If you don't have much else demanding power from it, you may get by with one of the less costly 350W - 400W units. I didn't see any junk PSUs in the list.

    Any of those except some OCZ models would be great in ca. 400W specification.

    That's the best price/perf. that I see on that site.

    Yeah, 350-450 will suffice as per calculations.
    I am ready to drop the settings to medium and even turn off the AA. Nothing less than that.
    Will the latest games run? Or should I go with GTX 550 ti?
  22. Not 550 but of you can 6790 or even 6800 series.
  23. 1920x1080 is a lot of pixels and texels for a HD 6700 series card to handle even at lowered settings. I wouldn't feel comfortable recommending anything less than a HD 6850 or GTX 460. I tried a GTX 550ti in a budget build recently at 1080p. Frame rates in the games I tested were just bad enough to be unplayable. The monitor I was using (or maybe it was the games) wouldn't allow changing to 1366x768, but I think it would have played OK at that Rez.

    If price prohibits getting a faster card, get the most you can afford. Worse case... You may just have to lower your rez to make it playable.
  24. if you are struggling to find money for a 6850, get a worse cpu.
  25. Best answer selected by bloodmage7.
  26. Worse CPU as in? I would have to go for G620 which has a slower clock speed and no HT.
    It will then affect the performance in general usage like browsing, copying files, etc.
    67xx series will not be able to play some games or are all the new games not playable at medium?
    Examples?

    If the resolution is 1600 by 900 are the games playable at high settings? Or maybe medium?
    How many frames did you get at medium settings at 1080p in most games approximately?
    For smooth experience is 30 fps sufficient?
  28. My little brother plays BF3 at medium at 1080p just fine on a 5770.

    Just fine means how many FPS? approx? Smooth?
  30. Yes smooth, otherwise he couldn't play it now could he ;D
  31. i have a hd 6770 and i can play all games @1600*900 at ultra with 40-45 fps
    and i can play bf3 at 1080p with ultra and no aa at a just playable 32fps
    so it should suffice for your needs!

    What if I get a monitor of 1600 by 900 that is 20inch rather than 1080p 21.5 inch then will the gaming experience of 1600 by 900 at high settings will be better than 21.5 inch medium?

    Hi bloodmage7,

    I searched the site you mentioned from where you'll buy your parts. I saw that AMD Phenom II X4 960T processor was in stock. This processor is great bro! It has 4 cores and it can be unlocked to 6 cores giving you much room for multi-tasking but don't consider the unlocking of cores as an advantage because the disabled cores don't always get unlocked. This processor will deliver nice performance and won't bottleneck mid-range Graphics Cards. I think it is cheaper than the Core i3 2120 also.

    If you can afford, try to get the GIGABYTE HD 7750 Card. It will handle most games at 1080p with settings lowered down.

    Regards,
    SmartGeek
  34. Hi,

    The card you mentioned is out of stock. I will see if I get from the local dealer.
    And what do you mean by settings lowered?
    Phenom is a aging processor and consumes more power than i3. I still think i3 is better.
