[HEXUS]

The fastest factory-overclocked GTX 680 to pass through the HEXUS labs.

Looks good, but as you point out, it's a very odd selection of outputs, and would rule it out for me completely (I'm still running a 1920x1200 24" monitor, and intend to keep those vertical pixels for as long as I can!)

Cool review and all but where's the stats to compare it to a stock 680 ?

EDIT: Ah I see you couldn't do normal tests because of no DL-DVI, maybe would be nice to get the stock 680 to do these tests too ?

whats the vram useage in BF3?

Am I the only one who doesn't like the white PCB? I mean if you have a matching white case to go with it then maybe, but, I would have still preferred the good old black PCB.

TBH one of the poorest reviews I've seen for a while, very disappointing.
No mention of the box contents, no comparisons vs other GTX 680's in terms of gaming, temps, noise.

I fail to see why this card was pitted only against a GTX 690, its not like thats its direct competitor, being more than twice the price.
I'm sure people want to see how it fairs against other GTX 680's so they can asses the increase in clock speeds and evaluate the cooler - to see if its worth the £455 price tag.

I have just ordered one of these (to replace my Sapphire 7970 with Accelero Xtreme plus 3, lovely card but sick of AMD drivers, nothing but problems recently since cats 12.4 and above !!!)

Was abit hasty as didn't check reviews closely enough and now see I need x2 8 pin pcie power connectors, and lack of DVI port !!!

Luckily it comes with 2 adaptors, mini hdmi > hdmi & hdmi > dvi and I just ordered a dual 6 pin to 8 pin pcie adaptor £3.99 here

The card comes with x2 dual molex to 8 pin pcie adaptors, which are abit pointless aren't they ? As they don't supply enough power to the 8 pin pcie (120w iirc vs 150w required)

Each molex connector should be rated up to 11A, so assuming the PSU is up to the task, feeding an 8pin with two of them should be no problem.

Ahh ok cheers mate. I did a bit of scouring overt the web and found mixed opinions on it so was unsure. the one that clinched it for me was on the EVGA forum where one of the support staff there adivsed uses of a classifed model to use a dual 6pin to single 8pin as it could supply enough power as the 8pin interface needs 150w.
The 6pin pcie inteface provide 75w each, so x2 = 150w.
Apparently the molex intefaces provide 60w each, so fall short at 120w.

I got that dual 6pin PCIE to single 8pin PCIE connector to be safe so i'll be using that.

Nice card btw, I may bastardise it a little bit though and slap my Accelero Xtreme plus 3 on it, its kinda noisey when the stock fans ramp up !!!!

And specifications you should never provide more than something like 18A on a single 12v rail But those ATX power specifications were ignored a long time ago, so the limitation is mainly what the PSU can actually supply, and the rating of the connectors/cables involved.

I don't remember the gauge limits, but the (according to wiki.. I don't know where to look it up officially) the molex connector is rated to 11A. Wire gauge and length is probably limiting - this resource guesstimates a 5A limit for an 18 inch 18awg cable, which is where the 60W limit is derived from. PCI-E cables should have thicker gauge so can take more (or there are just more of them), but equally you could use shorter length molex cables.

i wish i could spend £455 on just a graphics card.......sigh.....maybe one day
