gigabyte 990xa or fx ud3 for sli/8320

Eylogimenos · Oct 20, 2013

Hi guys, i want to build a new system

spec :

8320 with 2 x 660ti's in sli (140euros only in greece i searched all options and this is giving me best budget option in my country)

so problem is i go for 990xa or ud3 for sli? i want a fully playable sli system and for overclocking im not go more than 4.6/4.4 or something like that for oc.

any ideas? thanks a lot.

I would go for the 990FX UD3 given the choice.

is it really worth it? because is like 40-50 euros more mate and im in Really on a budget. any other option for mobo?

Look this psu :

is good enough for the 660tisli+8320? i dont have money to spend on a real psu like corsair. :/

Budget restrictions is the other concern so in that case there is nothing wrong with going with the 990x especially with that HIGH a price difference. Use the difference towards a better PSU since all your components are going to be relying on it for good and stable power. Recommended for 2 x 660Ti is 620watts http://www.realhardtechx.com/index_archivos/Page362.htm so a quality 650watt will easily handle it.

mate i found powertech for 35 euros, 750 watts. Here is what it has :

DC Output +3,3V / 24 A
DC Output +5V / 30 A
DC Output +12V1 / 22 A
DC Output +12V2 / 22 A

Main connector (20+4 Pin) x 1 (12V (P4) 1x12V (P4) 12V (P8) 1x12V (P8)
PCI-E (6 Pin) x 1
PCI-E (6+2 Pin) x 1
SATA x 6
Floppy (Y-cable) x 1
IDE x 2
Ανεμιστήρες 120mm x 1

can i use it ? how i can have 2 more 6pin connectors? should the cards when i buy will have a cable modular solution inside? any idea? what should i buy?

here is the site in greece with all the prices :

thanks a lot.

It is crap and only has the power rating of 550watt unit. It is lacking on the +12 volt rail and only has max 40+amps on there. This 650watt Corsair has 53amps on the +12 Volts and is a true 650watt unit http://www.visionstudio.gr/prodinfo.asp?id=23359&cat=17

Another good unit from XFX http://www.skroutz.gr/s/348198/XFX-ProSeries-650W-Core-Edition-Full-Wired-Bronze.html

Thanks a lot mate for ur answers, how about this? is this better than corsair?

http://www.skroutz.gr/s/3048827/Thermaltake-Smart-SE-730W.html

do u like it?

it is saying 2 way sli and a better price.

Im really stuck now in the mobo. How much is the difference on sli from 990xa to 990fxa? maybe i have an option close to 100 euros for the 660tisli +8320 combo?

Here is all the cpu's in greek stores :

Eylogimenos · Oct 20, 2013

Sorry i mean for the motherboards lol

cpu im not changing im gonna stick to 8320 + 660ti sli combo.

http://www.skroutz.gr/c/31/motherboards-mhtrikes.html

here is the motherboards. Im looking for the most stable+cheapest sli i could possibly built with a nice overclock no need to get 5ghz or something because i saw from benchmarks doesnt give +4fps from 4.4 to more. so... motherboard+memory combo is my real problem here.
Maybe i need more than 1600mhz corsair 4x2 ram (on hz) to be more stable at oc?

rolli59 · Oct 20, 2013

Eylogimenos :

The TT smart has no reviews yet but is made by CWT so should be OK although not as good as Corsair, XFX.
There is very minimal difference between SLI on X8 or X16 around 1%.

Eylogimenos · Oct 20, 2013

how about the memory? should i buy 1600mhz or i go for more with the xa for overclocking?

rolli59 · Oct 20, 2013

1600 or 1866 just based on which is cheaper, there is very little benefit from faster ram unless you have IGP that shares system ram like AMD's APU's.

Eylogimenos · Oct 21, 2013

so 1866 or 1600 mhz doesnt matter if i overclock also the fsb than the multiplier? which is colder? i think i do both of them.

rolli59 · Oct 21, 2013

If you overclock on the FSB then I would go with 1866 for more headroom but remember the memory controller is on the CPU and less speed and faster timings does not affect the controller as much as high speed and loose timings which can limit the actual CPU clock potential.

Eylogimenos · Oct 21, 2013

nice, so no big deal here, looks like im gonna bet on 8320/xa/2sliti/thermaltake 730w combo.

One more question mate. I dont have more money to buy another cpu cooler but im planning to buy 212 evo afters. Will the stock handle 4,2 , 4,4 ghz on gaming? im not going for more. how much temps i play?

rolli59 · Oct 21, 2013

Stock cooler will not handle much OC, maybe 200MHz if that. Best to wait with OC until you have the proper cooler.
