GTX 470 or SLI GTX 275's? - Page 2

post #11 of 19
I went from GTX 260 sli (almost the same as the op) to a GTX 470. In raw performance the GTX 260's in sli are slightly faster than the GTX 470 - IF the game has driver support for sli, and IF they scale well in that game.

However the GTX 470 handles AA and AF better than the 260's did, so the overall experience is that i'd much rather have a GTX 470 than GTX 260 sli.

PS just to be pedantic, you're not maxing your DX11 games if you haven't got a DX11 card. I know it's early days for tesselation, but a GTX 275 won't do that.

Mafia II with physx on high, the witcher, black ops, new vegas, nba2k11, WoW
from 1 275 to a 470 is a no brainer but from 2 275's to a GTX 470?
Aside from DX11 what else would i be gaining from getting a 470.
I'd be losing fps even in DX10/9 games.
So is it worth it to "upgrade"?

Judging From your Question, and not caring about DX11, i would not recommend you to get 470 for 4 reason

1) SLI 275 to 470, even if 275 perform better, chances are, you'll not notice anything unless you really cares about your numbers and FPS

2) Not alot of game use Tessellation feature beside most hyped up FPS game, as of now is almost like a gimmick to a 3D TV or a PhysX feature

3) Kepler (Geforce 600 series?) will be out around within 1 1/2 years to 2 Years, which is 2.7 times the improvement over Fermi

4) Unless you want Tessellation, and DX11 into your game, i wouldn't "upgrade" it


SLI 275 to GTX670 (Kepler), then yes, if what people said is true about 2.7 times faster, if 470 to SLI 275 for example is -5% in performence, then 670 to SLI 275 will be around 53% increase

I am just not in dx11 mode

Everybody thanx for the replies
Still not sure what to do

No DX11 Tessellation.

Totally not worth it in games right now.
Later next year, maybe.

There's less than 20 games that use DX11 right now, and not all of them take advantage of tessellation.
Most of the ones that do use tessellation don't use a lot of it, so the effect isn't very dramatic.

AVP for example.

Dirt2 is another example. Tessellation isn't used in the cars. Only on the audience, water, and some background objects. (Stuff you won't notice during a fast race)
http://www.bit-tech.net/gaming/pc/20...-look-dirt-2/1


3rd example would be Battleforge. It is DX11 capable, but it doesn't use Tessellation at all. It only uses DX11 for the lighting effects.

I had the same question as the OP a while back. I had gtx 275 sli and wanted to know if an upgrade woulde be worth it. It was worth it to me for 2 reasons. I wanted a single card solution that would lower noise and heat. I went with a 570 and I love it. I had my 275's OC on air, and my cards ran hot as hell. I also had to run the fans at 80% so it was loud. With my single 570, i havn't had time to OC yet, but i don't see much of a difference in terms of gaming, but my PC runs much cooler at stock fan speed of 40%. I don't even hear the gpu fan running. That being said, if you want a cooler quieter case, I would go for the msi twin frzr 470 or 570. if your looking at gaming performance, I wouldn't upgrade.

Note: I am not arguing here. I am just stating an opinion and providing links as a basis of for it. When I say "you", I mean "you" in general and not any specific person.

A single GTX 275, in good condition goes for roughly $125 on eBay right now. If you gauge for shipping, you might be able to get slightly more. So that is about $300 you might be able to get (assuming these are not water-cooled).

Based on benchmarks from Tom's Hardware a GTX 280/285/275 SLI set-up is comparable to single GTX480 or GTX570. You can purchase a single GTX 480 on Craigslist or eBay for $300 easily. For 50 dollars more you can get the more efficient GTX 570 brand new.

This means that with a little bit of effort you can turn the GTX 275 SLI set up into a single card that uses less power than two would, makes less noise, has no micro-stuttering, and has additional features.

However, if you wait, this will not be possible; the GTX 275 is not going to become more valuable, it will become less so.

I have my GTX285's clocked on water+mods at just shy of 800mhz.. comparing that to my GTX470 in the same rig- with the 470 clocked at 775mhz core I get the following in Vantage:

GTX285 SLI- 25,673 GPU score

GTX470- 19,725 GPU score


I would keep your 275's.. there are plenty of mods for them as well, to get them closer to 900mhz for stable daily use too
