Here is some reviews from happy OcUK customers.
just wow..
What can I say about this card.. bought it on weekly offer so worked out cheaper than the stock speed Gigabyte 780 which was sweet.
Upgraded from a GTX 580 and wow, the difference in performance is way more than i anticipated. Coupled with my i7 2700k 4.2ghz i'm easily reaching 80-110 fps on BF3 with EVERYTHING on max, temps at a max of 63 so far which is a HUGE difference from my previous card.
I was a bit hesitant at first about buying a Gigabyte graphics card as I have always gone with EVGA, however I don't regret my decision and nor will you if you buy this. simply amazing.
Quality Graphics Card
Quality card maximum overclock 1215Mhz on the core, and with fan speed of only 57% without touching voltage.
Bought mine at the end of May 2013 when it was released, cost £569.99 then, now it's £509.99 and £479.99 on week only offer!
WOW
This card oozes class. This card cruises through battlefield 4 no sweat. I am on on full ultra at 1920x1080 and am maxing BF4 out. I have had no issues. Shadow play is awesome. The cooler is amazing. At 75% you can hear a low whooshing of air. I have only needed around 60% which is extremely quiet, barely audible.
one happy happy here
paired with a 2600k @ 4.7
Excellent!
Excellent card at £399 with 3 games.
Boosts to 1124 from stock, with a maximum overclock of 1254 without increasing voltage.
Memory boosting to 7Ghz.
The card is very quite. The sound of my corsair sp120 fan on my h60i is louder.
At 1080p you cant go wrong. 290 or 290x better at the higher resolutions but are loud and run hot.
Highly recommended!
seriously good bit of kit
Upgraded from reference 680 SLI to this single 780 - I am game at 1440p and I am really really impressed with this card - the extra memory and bandwidth are noticeable in performance - BF4 smooth on ultra and 64 player maps
likewise crisis 3 pretty much every thing maxed and great FPS
runs much quieter than my previous cards even under serious load and temps are ridiculously low - cant recommend enough - ill be going SLI when I can![]()
10/10
Ordered this Tuesday evening/night sometime and to my surprise it came Wednesday morning! so someone made my day a little happier!
As for the card, i can find no fault so far. Very quiet & beastly performance.
Very powerful and very quiet!
Firstly I will say how quiet this card is, I have a computer for the living room with an Antec P82 case and I cant hear the fans over the low thum of the case fans. Seemingly no change in volume under load which is very impressive. Temperature has yet to rise above 65c while gaming either and thats after 3-4 hours on various sessions. Gaming at 1080p is silky smooth (60+ FPS) on all titles (BF3, Crysis 3, AC4 to name a few). That is paired with a 2500k at 4.4Ghz for reference. All in all very impressed! Highly recommended.
