Hello, As you can see in the title, I would appreciate input on what would be a wise decision.

Specs: Motherboard= (Gigabyte) 970a-ds3
Cpu= (AMD) 8320 stock hsf/clocks
Gpu= (Sapphire) 7850 1gb overclocked 1200/1225 with Artic Accelero 65c max
Ram= (Corsair) 8gb xmp profile at 1600
Psu= (Corsair) cx600 builder/entry level
Fans= 6 120mm
SSD= 1
HDD= 2

Option 1. I keep everything the same and get either a 770/780 or 7970/7990 or R9 280

Option 2. See below specs.


Motherboard= (asus) Sabertooth 990FX R2.0
Cpu= (AMD) 8320 hyper 212 evo 4gh+
Gpu= (Sapphire) 7850 1gb + 7870 2gb crossfire
Ram= (Corsair) 12gb xmp profile at 1600
Psu= (Corsair) tx750
Fans= 6 120mm
SSD= 1
HDD= 2

The positives behind option 1: Well I'll have a damn good gpu with no worries for a while. Also could(not important) begin a second rig or sell.

The negatives behind option1 : Motherboard is 4+1 so no overclocking 8320, psu may not be enough for previous mentioned cards, mobo too small for CF/SLi later on.




The positives behind option 2. 8320 can reach it's full potential, Crossfire, when CF doesn't work I have a 7870, Future proof mobo, bigger psu for future a add-on, more ram.

The negatives behind option 2. Crossfire driver issues, only 1gb shared memory, possible heat woes( 6 case fans and one gpu with artic accelero, possible of course but I doubt it)


Side thoughts: Is an overclocked 8320 that much better than stock for gaming, I mainly play Arma 2/3. Should I upgrade everything and keep my 78501gb?


Thank you to anyone who reads all of this and answers. So what seems to be the logical choice here?

I think you should go with a single GPU upgrade.
Advantage of single higher end GPU than two low end GPU's in crossfire/SLI :
1) No microstutter below 30 fps. (they are very irritating)
2) Reduced load on PSU.
3) Guaranteed performance improvement in all SLI/cfx and non-SLI/non cfx gaming titles.

In my view you should go for an R9 280x or an even cheaper and better GTX 770. (both these GPU's offer extreme performance in next-gen titles at 1080p)

You wouldn't have to upgrade your PSU if you were to crossfire.
Your current motherboard is capable of crossfire

stick with everything you've got and just buy another hd 7850... Or just buy the GTX 770.

no reason to get a new $180 board just so you can get another maybe 5 FPS

Yeah I figured, I'm overthinking things too much. Thanks for the quick help.

I meant to select you as the best answer, oops. My board supports it but my gpu is too big. You're right though about the overclocking, I just thought I was doing myself a disservice by not overclocking 8320. 770 it is! Any particular one I should stay away from?
