Tri 480 GTX to AMD 7990

[el etro]

I have 2 evga gtx 480 oc, before 2 4870x2.

want to upgrade, power or sli/crossfire issues are none problems to me. (1600W psu, 220V at the wall)

I also think of a 7990, or 2 770, a single card leave room to add second so I prefer single card ( dual gpu or not).

prices in argentina are crazy and avaliavility sucks. If I buy I want to fell it like my wallet will do.....

lets wait to see 290x prices after release panic.

Same as Russian thought here. Wait three months till price drops and Pick 2 Non-X 290(Or cross the frontier to pick two 780s in Paraguay if you have price issues here). The 290/780 Overclock potential is Tremendous.

I can't see how a single 290x is going to be much quicker than tri-480 sli. You'll need two cards and as Groove says 2x290 is probably going to be the sweet spot with the benefit of 4gb RAM per card. Just wait a couple of weeks and see what the 290/x bring but a 7990 while being good value is towards the end of its life cycle (not to say it's not still blazingly fast) but if you're going to keep the next cards as long as the 480's then 4gb video ram would be a wiser choice.

Even an 290X/Titan/780/290 non-unlocked and overclocked can beat the three 480s.

Fuse the posts if you think it's better, moderator.

It's not a question of whether they can beat the 480's it's a question of by how much! Notice I said I didn't think it would be much quicker than tri-sli. Sometimes one card may be quicker, sometimes maybe not.
Is a Titan/780 quicker than 680 SLI?
Here's a link to give a vague idea of how 480 Tri-SLI compares to 680 SLI (which is faster than 780 or TITAN.

I used the word much for a good reason. If you think it's worth upgrading from his current rig for 5-10 fps in some games fair enough but I for one prefer upgrades where I really notice the difference.

I mean it only for information purposes. What i meaning to him is to get hid of the power-hungry SLI....

 

[Jacky60]

He didn't say he wants to save power he said he wants an upgrade. No single GPU card will be much if any of an upgrade but 780 SLI or 290/290x xfire would be a significant noticeable GPU upgrade. 480 tri SLI is power hungry and normally very hot but he's going to water cool so heat shouldn't be an issue. I don't think the 7990 would be vastly quicker than Tri-SLI either as Grooveriding said 680 SLI wasn't much of a step up for him.

Wait for an aftermarket custome factory overclocked AMD 290X
the stock AMD card has a 512bit bus with only 5000Mhz ram.. wait for third party board makers to start adding 6000-7000Mhz ram versions and upping the GPU clock with a big factory overclock. may even be 20% faster then the stock card.

The only thing i look at myself.

- At 1100Mhz, HD 7990 does. Its something like GTX 780@1400Mhz in terms of FPS rates. At 1300 Mhz+ Titan can beat 7990. Tri-Sli 480 perform between GTX 660-660Ti Sli.

*Anyway, i said to OP to grab dual overclocked(Lightning/Classified/HOF) GTX 780s.

Using VP points(click this link!) list of performance, to explain it to OP:

3x480: ~330 VP
7990: 353 VP
GTX 690: 380VP
7990@1100Mhz: 401VP
GTX 780@1350Mhz: ~400VP
Two GTX 780@1300Mhz:

The memory overclock may show notable gains once the resolution goes up, generally.

Two R9 290's or three 7950's; cheapest models.

So best possible single 780 scenario is a 20% improvement which would take him from 50fps to 60fps in said hypothetical game. It's 10fps at under 60fps which isn't much of an upgrade and hardly worth disassembling the water loop for. I agree dual 780s are good idea but dual 290/290x is shaping to be the best choice as long as they're not much more than/same price as 780s. The benchmarks I've seen see it, the 290x destroying the 780 and that seems to be in quiet mode. Who can tell what Uber mode might bring. Two vanilla 290s sound like where it may be at.

Now that the 7970 are down to $230 each, how would dual 7970's be? Or even triple 7970?

Dual 7970 is like 7990 or 1350Mhz 780 as in a bit faster but not very much quicker than 480 tri-SLI. Wait until end Oct and we'll see the 290/x and prices. 7950 tri-fire is sooo cheap for what you get (3gb ram per GPU) and OC close or good as 680 tri-sli which should equate to nearly 780SLI or 290xfire for 2/3 of the money but it's worth waiting 3-4 weeks for the fog to clear and prices to drop. Triple 7970 would give you at least 50% faster than current setup in pretty much all games and probably quicker as would triple 7950 at same clocks. Also your PSU needs to stretch its legs a bit and tri-fire would give it some exercise. If you're used to tri-SLI/trifire I'd almost certainly buy 3 x7970's if I were you BUT wait to see what happens at the end of this month as you can still buy 3x280x either way even if all 7950's/70's sell out.
