    If you buy a 4GB version of the R9 285 then it will be the same card as the R9 380.

    AMD processors have terrible AVX performance (and just general floating point performance), and it seems from a quick search that AVX is becoming more used in CAD programs. Ill see if I can find an i3 with hyperthreading that would fit in the budget, because it would have AVX and AVX2 instructions that actually work right.
    You will also want to get 16GB of RAM in the system as CAD work tends to like RAM.

    This CPU and MB are not much more expensive:

    From the few tests I looked up it looked like pure core count actually lost to better efficiency CPUs in terms of core speed and instruction sets, which is why I think that 4 thread Haswell based i3 would be better than a 6 core AMD Vishera. And you should be able to select a faster bootstrap base clock for the CPU to overclock it by a set amount even though it is not an unlocked processor. If my math is right (which it probably isnt lol) then the overclock would result in a 4.375 GHz clock speed.

    And if you reuse your current RAM (probably 8GB?) and add in this other 8GB:

    All the tests I have seen so far for consumer GPUs in CAD stuff show Nvidia with a definite lead over AMD in 3D work, and the GPU doesnt even matter in 2D work anymore. However, if the R9 380 does in fact launch today and is really selling for only $200 then that is probably the way to go.

    Thanx Enigma :) Altho when i typed CAD - Canadian currency, i should have thought people would read it as auto cad hehe
    It's gonna be pure gaming PC. Trying to find best parts for that budget. It's gonna be a build for Canadian Army vet i know.

    oh. lol Im dumb.
    You might want to look at the reviews and compare the R9 380 vs the GTX 960 and see which comes out ahead, both are around the same price it seems. $200-220 for the 2GB model and $270-300 for the 4GB model.

    EDIT: Benchmarks seem to show the 380 being anywhere from 2-10 frames per second above the 960 in every test, so go with the 380.


    If this is just a general update for a gaming PC then you might want to wait a couple more months to decide on a CPU, because DirectX 12 promises to make the CPU less necessary for gaming and make core count better than high GHz. We wont know just how well that promise holds true for a a little bit longer, but you wouldnt want to buy into one camp now and find out it ended up being the wrong move. And Intel is releasing their newest Skylake chips in just a few more months as well, so if they put out a Skylake version of an unlocked dual core or DC with hyperthreading that might be a very attractive chip. So with everything shifting within the next few months here, I wouldnt advise buying a CPU right now.



    What is your current hardware?

    Maybe, it might make much better use of multiple cores which may favor AMD. But, on the other hand, new version adoption is direct X is super slow in many ways. If you want a computer now I wouldn't worry about it. If you always wait for the next best thing...

    Currently I have a really hard time recommending AMD cpus in anything that's not a bargain basement internet/office terminal kind of thing or like Media PC, where the IGPU has an advantage.
    Especially when you bring up gaming. Per-core performance is still the most important thing there. A billion junky cores doesn't win against a couple spiffy ones. For the most part.

    Also, a super easy way to save money is to not buy an extra CPU cooler unless he's actually going to use it for overclocking. That's your money to bump up to an i3.

    DirectX 12 is a very easy upgrade from DX11 though and it doesnt really have too many extra features since it is mostly an efficiency update over DirectX 11. There are already some companies that are planning on releasing DX12 versions of their games shortly after it's launch. There are also already quite a few cards out that support DirectX 12, so it isnt like people need all new hardware that is yet to be released.

    His current specs are
    AMD FX(tm) 4100 quad core 3.60 ghz
    amd radeon 7800 series. 2gb.
    Using gpu-z he couldn't tell me if it was 7850 or 70
    Gonna try to figure it out, when he gets back today.

    Ok well I bet than R9 380 should be somewhere between 75-100% faster than the current GPU so that is pretty good. I think that i3 with hyperthreading is still your best bet for a cheap CPU, and you can afford the difference by not getting an extra aftermarket cooler like Rbstr said. The i3 will have better minimum FPS and just be a better all around CPU to have in the PC, and is leaps and bounds better than the FX-4100. That should bring the total in the new parts to between $450 - 500.

    Thanx Enigma and Rbstr. I'll consider all possibilities.

    Pretty much the same price for the 380:
    http://www.newegg.ca/Product/Product.aspx?Item=N82E16814161470&cm_re=r9_380-_-14-161-470-_-Product

    Worth the $5 IMO to get anywhere between 2-10 frames per second more
    The more expensive models for $30-40 more are because they have 4GB of vram instead of 2GB. Honestly I dont know if the extra memory is really worth it on a card that doesnt have the raw power to run at the highest settings in every game anyway. It doesnt seem like the settings this card is made for would really fill up past 2GB of vram.
