Nice! it seems most 3770s clock pretty well, well at least better than 4770s so I wouldn't be surprised at all if you could hit 5.0. That is sort of why I haven't upgraded yet especially due to the negligible performance difference between the two.

Yes, I think I will be lapping the cpu as well, and applying better paste to the internal heatsink. I've always used Liquid Ultra cooling paste, pure metal, but can be harmful. But, always achieved about 3-5 degrees lower than the best cooling paste (IC Diamond for example). I have not yet tried it on the internal heatsink yet, but I might give that a go. I have the Noctua NH-D14 heatsink. Which one do you have?

EDIT: Going a little bit off-topic I realise..

But, on topic, I think temps also play a big role. I've managed to lower my GPU temps about 13-14 degrees C on OC, compared to stock (no OC). That's a huge difference. But it seems as if my card has some sort of temperature wall of 70 degrees C, above that, OC becomes significantly more unstable. So, with all modifications, I hit a max of 65 degrees on 1.212v when playing the most gpu intensive games. Had to do a series of mods to my gpu and case airflow. But it seems to help. Usually with V-sync on, temps stay below 60 degrees when playing games like AC4 or Tomb Raider. Of course no high AA settings, preferably off, I think that looks better, more crisp than with any type of AA (at 1440p that is). But that's a matter of taste.

more is more..

I need to delid mine also. I'll get around to it eventually, although, I'm not sure what method I want to use (Razor or Vice).

I have a corsair h40 on mine currently but that will change soon. Surprisingly I've been getting great temps with it despite my overclock and one fan on it lol. smile.gif

That is what I was thinking smile.gif

Your issue is the FPS @ 120hz refresh rate really using a single card, that said if you are feeling flush there is a KINGPIN on EBAY for GBP661 (plus customs duty) today that might do the trick!

Shouldn't use the word "wait" when it comes to gpu unless of course you know an official date of the next line up of gpus. If you keep waiting you might have to stick with those 670s for a long time. People go on for years waiting for the next best thing but there will always be a next best thing right around the corner. So, no need to wait, just pull the trigger asap and be happy. biggrin.gif

Single gpu always has less issues than sli (fact).

Thanks guys! I'm gonna go for one and pull the trigger once my PSU RMA replacement has arrived.

Should I go for the:

  • Gigabyte Windforce 3x for £526
  • EVGA SC ACX for £560
  • EVGA Classified ACX for £603
or the

I've always had the best luck with EVGA products. Go for the EVGA Classy man! You won't regret it!thumb.gif

do you think maybe my processor? i have a 3770k @ 4.5 ghz

I've tested a little regarding CPU influence. These are my results on an i7 860 CPU:

First:

4.1 GHz - HT On (4 cores, 8 threads)
GPU 1300mhz - 3750mhz @ 1.212V
Valley Extreme HD: 77.3 fps

Second:

4.45 GHz - HT Off (4 cores, 4 threads)
GPU 1300mhz - 3750mhz @ 1.212V
Valley Extreme HD: 78.9 fps

It's not a huge difference, but overall seemed smoother as well. I think CPU has an influence, but maybe too high clocks might adversely affect performance? Or other programs running in the background. Or even multimonitor usage?? Didn't test that. I have 2 monitors active atm.

more is more..

WoW just got a 780 Ti but my 780 DCII OC is almost as fast. Only 500 gpu score difference in Fire Strike, Both OCd to their max.
Hope it will perform better in games otherwise i am really doubting it was worth the update.

I went from GTX 780 SLI to single Ti due to mini ITX build so wanted to get the fastest single gpu card but kinda dissapointed with the difference.

Gonna fire up some games

I'm not really too surprised. My last Firestrike score was around 10,100 which is quite a bit higher than a reference 780 ti (no OC). I'm on the fence about upgrading; not sure it's worth the trouble. Still undecided however. rolleyes.gifwink.gif

Please post your opinion once you've had a chance to play a few games with the new setup.

On a side note, is it normal that Fire Strike score barely increases with an OC of 780 Ti? I gained maybe a few hundred points from +250 core clock. But Fire Strike Extreme yields much better gains, more than 20%.
