GTX 650ti BOOST vs HD 7770

Evan10800 · Apr 18, 2013

I currently have a Radeon HD 7770 and I was wondering if it would even be worth it to replace that card with one of the new GTX 650ti BOOST editions? Or should I just get a second 7770 to crossfire?

1 on 1 the 650Ti boost is more powerful but it is weaker than a set of crossfired 7770's.

FCAT tests have shown that Crossfire is badly broken. AMD admits there is a problem and they're working on it, but a fix isn't expected before July. Short version: FRAPS will show a much higher frame rate, but many of the frames are runts, or get dropped before making it to the display. www.pcper.com has a very in-depth analysis of the FCAT testing.
The GTX650Ti Boost would be a nice jump over the HD7770. It is three tiers higher on the GPU hierarchy chart.

It depends on the game you are playing. In many cases such as Battlefield 3, the Crossfired 7770's scale really well and can offer performance close to that of a 7950. In other games, the advantage is almost nothing.

Overall, I think getting another 7770 would be the best value, but again it depends on what games.

Onus :

So you're pretty much saying that getting the 650ti BOOST is the way to go at this point?

Right now, I've been playing more MMOs like WoW, RIFT and so on. I do play some games like Batman AC, Farcry 3, BF3, and Hitman. But lately, I've been more into the MMO scene.

Do not Crossfire a pair of 7770's. This series of articles gives plenty of reason to avoid it at this time.

It looks like the GTX 650 Ti Boost will give you about 40%-50% more performance, plus the ability to enable PhysX and Adaptive VSync.

until they actually fix it and that should be released in a driver or hot fix solution. at which point a pair of 7770's will be more powerful.

Yes the GTX 650ti BOOST is faster then a 7770 no question about it.

Onus · Apr 18, 2013

Crossfire may or may not be fixed, maybe by July, maybe not; OTOH the GTX650Ti Boost offers a substantial improvement, now, and you can add a second one in SLI later (SLI works) if you want even more power.

bgunner · Apr 18, 2013

the thing is nobody is considering that the 7770's will be crossfired. 2X 7770's will out perform a single 650Ti boost. Like I mentioned in the fist post Yes the 650Ti boost is more powerful than 1x 7770 But if you crossfire then the table turns to favor the 2x 7770's.

That's true but cf is not working right now so op shouldn't risk those issues.

We actually get that, but Crossfire is a bum deal right now until AMD does something about it. If you consider that a single GTX 650 Ti Boost is about 50% faster, then even assuming they fix Crossfire a second 7770 is not going to be a big improvement over that, if at all.... (and he still won't be able to enable PhysX in his Batman Arkham City game).

Evan,
The GTX 660 is a much better deal right now. They only cost about $10+ more, but they come with a free copy of Metro: Last Light, which the 650 Ti Boost does not.

Onus · Apr 18, 2013

Crossfire should not be considered until it is fixed, and the fixes have been independently verified. Crossfire will yield higher FRAPS numbers, but what the gamer actually sees is crap due to runts and drops.

bigcyco1 · Apr 18, 2013

Onus :

+1

The charts I posted demonstrate that the GTX 650 Ti Boost is about equal to a pair of 7770's in Crossfire using the FRAPS FPS (check the GTX 570 as a yardstick). And that goes without the associated driver issues and problems with Crossfire game profiles. This is starting to look like an easily solved dilemma.

Onus · Apr 18, 2013

I agree, Matto. The GTX650Ti Boost would be a nice upgrade, and looks like the best choice here.

I thought this was only with certain Cards?

Onus · Apr 18, 2013

cstahler92 :

Nope. Follow-on articles at PCPer showed that it extends up and down the line, actually getting worse at the "bottom" end (they didn't go below the HD7850 in their tests). There were a very few exceptions in which Crossfire actually worked, but I don't remember what they were.

That's correct, it only applies to those AMD cards that are able to be Crossfired.

Thanks for all the replies. I think I'm going to start saving up for a 650 BOOST.
