R9 Nano vs Crossfire Radeon 7790s?

Cam P · Mar 22, 2016

I built this rig in late 2013. I plan to sell this for $850 (but will negotiate) on Craigslist (so far 1 person contacted):

Here is my planned build:

AZZA Mini ITX Case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811517029
MSI AM1 Mini ITX Mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130759
AMD Athlon 5350: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113364
Avexir 8GB DDR3 1600: http://www.newegg.com/Product/Product.aspx?Item=N82E16820011003
Deepcool 650W Gold: http://www.newegg.com/Product/Product.aspx?Item=N82E16817328007
2TB 7200RPM Seagate: http://www.newegg.com/Product/Product.aspx?Item=N82E16822148840

This comes out to about $272.20 after coupons, rebates, and shipping, but I'll round it up to $280.
Suppose I sell my computer for $760, that gives me about $480 to spend on a graphics card. Here's what I had in mind:
R9 Nano: http://www.newegg.com/Product/Product.aspx?Item=N82E16814131679

I know the CPU and mobo is a big step down, but given the better GPU, do you think it will run games at a higher FPS than my current build?

Or post a better build of a PC with the same case if you want
Also I found that I could build this for $723.12 using pcpartpicker.com

Never plan on running crossfire unless you have two (two top end cards for example).

One card, even if its slightly slower than two weaker cards is almost always more worth it simply because crossfire and sli come with their own issues (heat, compatibility, bugs).

If you can fit two 7790s, why would a nano be the alternative? Why not a full size card?

I'm trying to sell my current build (of two 7790s) to make a smaller rig (mini itx) with better graphical performance, while taking out some CPU and mobo performance. Read the whole question description.

That 5350 is way too weak of a cpu to pair with even one 7790 let alone a Fury Nano.. It will not game well at all in most games as it is way too slow per thread, and even in games that can take advantage of all 4 threads it will still be slow. For a gaming system Intel is currently the way to go. They have low TDP options so you can make your small form factor build that will actually run games decently. Your current system will probably be faster by far is most games than a Nano with a 5350..

So if I were to use Intel instead of AMD, here is the mobo I found:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813138404

but its $40 more expensive, and the cheapest i3 is $70 more expensive:
http://www.newegg.com/Product/Product.aspx?Item=N82E16819117447

So maybe one of these CPUs instead:
Pentium: http://www.newegg.com/Product/Product.aspx?Item=N82E16819117545
Celeron: http://www.newegg.com/Product/Product.aspx?Item=N82E16819117301

So would the celeron or pentium do? Or would I have to jump to an i3? I think I would be able to afford the i3 if I searched for a price on a site other than newegg.

You see the thing is you are paying for a high end video card, cheaping out on the cpu will just bottleneck the GPU. You need an i5 to match the Nano or it is not worth it IMO.. Celeron s, Pentiums, and i3's are not up to the task. Your current CPU the 8350 is better than a pentium or celeron, even an i3 in non single threaded sensitive games. Always better to save your money and get the right hardware than getting low end crap and wasting money.

For a balanced gaming build, a rule of thumb is you typically want to spend around twice as much on your GPU compared to your CPU. Pairing a Nano with an i3, you're spending more like 4 times as much on your GPU.

So it looks like I may be spending a little more than anticipated. but I'm also trying to sell another graphics card (1GB Sapphire 7750), an old HP Pavilion Slimline desktop, and a Lenovo laptop, so I'll try to use those to make this into a better build. If I'm able to sell all of those, I think I'll go for a higher end i5 or an i7.

Good rule of thumb; Sounds about right.
