Replacing 680SLI with 780Ti

No. Don't


There is no point as the 680 sli is the same as 770 slightly and the gtx 770 sli I such more better than the 780 ti.

So why downgrade on performance?

The 690 smokes all right now. The 780ti doesnt even give it competition but theb690 is a dual gpu. Basically two 680's on one pcb so I would absolutely keep the 680's. If you must uograde from what you have now wait for the next series from nvidia. Your 680sli is a very nice setup.

But why?

Why pay so much money for...practically nothing?

If you are willing to pay fine, go for it and sli later. But then you'd be in a similar situation because the 800 series will apparently come in late q1 2014 or early q2 2014.

I think you are just wanting to get something new to get something new. I've been there... If you just want something new and will admit it and are fine with spending the money then go for it. Otherwise wait for maxwell!!! It is illogical to buy a GPU now even though you get good performance because you are worried about future performance

Hi Jupi. I was in the same position as you. I had a Zotac 780GTX. Bought June 2013 (upgrade from 680GTX) for £550. Then the 7880Ti was released. I decided to sell my Zotac 780GTX. It sold on ebay for only £315. I was furious. I lost £235 on a card only 6 months old and which had 5 years warranty!. I needed a new card. I saw on UK Amazon the Asus 7990HD reduced from £975 to £438. I snapped it up. Been using a month. Intial feelings were its a good card, but it gets too hot and forced my cpu, mb and overall temperatures up. My pc kept crashing. Also, AMD software/drivers were a total ball ache. I decided to send the 7990HD back to Amazon and I got a Palit 780Ti from Dabs for only £501.99 (free delivery and 3 years warranty). Got it yesterday and ran benchmarks. This is what I got:

Asus 7990HD Heaven 4 = Score 1621, FPS 64.3, minimum FPS 8.6, maximum FPS 157. CPU temps 51c, GPU temps 75c at 70% fan speed (I'm not sure why FPS dropped to 8.6).

Asus 7990HD Valley 1 = Score 2897, FPS 69.2, minimum FPS 26.6, maximum FPS 123.1. Extreme HD. CPU 55c, GPU 75c, mobo 40c at 70% fan speed.

Compare this to Heaven benchmark results for my Zotac 780GTX (also ultra settings):

Heaven 3 = Score 1519, FPS 60.3, minimum FPS 28.3, Maximum FPS 155 (I didn't have Valley 1 at the time, so didn't test).

Now compare my Zotac 780GTX results to my palit 780Ti -

Palit 780Ti - Heaven 4 score = 1343. FPS = 53.3. Minimum FPS = 9.9. Maximum FPS = 119.1

Palit 780Ti - Valley 1 score = 2325. FPS = 55.6. Minimum FPS = 8. Maximum FPS = 120.2

I am really shocked with the Palit results. I don't know why it is so low. I don't know if I should go back to the 7990HD or keep on using the 780Ti. All I know is that I truly regret selling my Zotac 780GTX. That was a damn good card. The Palit was made in China and I have read on Amazon reviews for SSD's that the ones made in China performed poorly when benchmarked.

The 7990HD has got potential but it was too much of a ball ache to use (overheating, games crashing, BSOD, etc). Also I was a bit disappointed by the 7990HD bench results as it beat the 780GTX by only 101 points. It should have accrued a lot more points. See my Amazon review -

BTW, I read yesterday on videocarz.com that the new Maxwell gpu will not give the same improved performance over kepler, as kepler did over Fermi. The Maxwell will only tweak and fine tune performance over kepler by a small amount. If this is true, then probably not worth getting Maxwell. Just get the 880GTX when it comes out, but I shudder to think of the price tag (£600+). As for me, I am going to try and find out why my Palit is scoring so low and try to fix it. Benchmarks are poor but when I run games like crisis 2, Mass Effect 2 & 3, it gives good FPS (60/62 - same as 7990HD). In Crysis 3, it gives 45-47 FPS (ultra settings). Bear in mind my 780GTX gave 32-35 FPS in Crysis 3 (ultra settings) and my 7990HD gave 60FPS (also ultra settings). Temps for 780Ti much better than 7990HD. Idle = 33c. Load = 68c-73c depending on game, but cools down quickly after quitting game (whereas 7990HD would remain hot for long time).

The 780ti is actually not very far behind the 690 as a single card. The biggest advantage to moving to a single 780ti would be that you could add in a second 780ti a few months from now and absolutely crush your previous build.
