GTX 275 to GTX 470 - Page 2

post #11 of 32
I did the EVGA step up program from a 275 to a 470 and it makes a huge difference. I'm getting around 14k folding as opposed to around 9k which is what i was getting on my 275. Also my 3dMark Vantage went up to 17151 GPU. Also my Furmark benchmark went up about 50+ FPS at the same settings and of course you get DX11. Well worth the cost.

Correction, 550 is the minimum for a 470. The 480 is 600 minimum. Most sites you'll see are highly recommending that you run at least 750 for both cards. Just a gentle FYI.

If you want, wait on it and I'll tell you my experience in two days or so. I'm going from a GTX 260 with 192 Cores.

The thing is, if he's using the Antec EarthWatts 650 (I think that's the only Antec 650 watt PSU) then that is PLENTY for a 470 or 480.

Yes, the recommended PSU's are 550 and 600 respectively, with people suggesting 700-750 watt PSU's.

But that's gross exaggeration; a 470 highly OC'd will be around 260-275 watts TDP, and a 480 highly OC'd will be around 325 watts TDP. That leaves 300+ watts available for the rest of his system. Assuming a highly OC'd i7 920 or similar, that's another 175 watts. So you're looking at around 500 watts, 550 MAX for a single GPU system. And assuming a PSU efficiency of 80%, you'll only actually draw less than that.

A quality 550-650 watt PSU would be more than enough for a single 470 or 480, and some people even run 2x470's on 750 watt PSU's with no problems and 480's on 800-850 watt PSU's.

I don't think it's worth it unless you get a good price on the GTX 275. I went from a 4890 (roughly same performance as 275) to my Crossfired 5770's and the only reason I did this was because I got them for $60 each. If I didn't get that price I would still have my 4890. I just don't think the upgrade is worth the price

No offense at all, but it's a bit tough to not recommend an upgrade for someone if you personally don't have experience with EITHER card that the OP has/wants.

Yes, a 4890 is roughly the ATI equivalent of the 275. However, a GTX 275 also has only 240 CUDA cores as opposed to the 440 cores of the GTX 470. That is a SUBSTANTIAL difference.

As well, the ability to run DX11 and its new features (primarily tessellation performance, which is extremely good with the 400 series) is a good selling point. His minimum FPS will also be significantly higher than his 275, and that in itself will provide a much more fluid gaming experience (trust me on this - i had a GTX 260 Core 216 (216 cores) and the difference between that and the 470 was unreal).

If he gets rid of his GTX 275 now, he can still get a rather good amount for it...if he waits to upgrade, he'll make a lot less for that 275 4-6 months from now.

So, OP...upgrade away, I've been in your shoes and I promise you that you won't be disappointed

A 470 is about the equivalent to a mildly oc'd 285. A 465 is the equivalent of ur 275, but with dx11 capabilities. Here is an article about ur card in comparison. It is technically a 465 review, but gives good comparison of ur 275 to the 400 family

I don't understand what the number of CUDA cores has to do with this. We're talking about performance, right? If the GTX 470 had 1 CUDA core but still outperformed the GTX 275 as it does, why would that matter?

I did roughly the same performance upgrade, and I'm saying that unless he has cash to throw around, it's not worth it. If he does have the cash, go for a GTX 480, assuming he meets the power requirements. If not, get a 5870, which is worse for tessellation, but the OP said he doesn't care about that.

I'm surprised noone's recommended flashing a 465 to 470 spec. There are a few brands that have been confirmed to work!
