So, i've been meaning to buy a new computer and still i'm in doubt about my gpu.
Anyone here that have this gpu can tell me if this is a good one? in wich settings can this gpu run ?

What is your budget for a GPU adn what do you need it for? Meaning; is MWO currently the most taxing thing your GPU will have to handle.

I had a 7770 OC handle max settings fine

[StonedDead]

I'm using an HD7770 right now. I run mine on medium to conserve resources some, not that I need to. It is capable of running on the highest settings with the PC I have. Asus 990FX mobo, FX-8120 8 core, 8 gb ram, HD7770, 750w PSU. You might want to OC slightly for higher settings. I think I might also need to upgrade PSU sometime to 1000w, had a slight issue when OCing the first time with it, display driver kept crashing and re-enabling. That may have been from not stepping up GPU voltage when trying to OC. (new at this, previously running HD6670 which didn't require or have available a voltage setting)

The 7770 barely draws any power. Runs off one 6 pin. I had mine running with my 450 continuous PSU.

I don't live in the USA so price might not be the best line of thought, but here from where i live i know that the price of this card is about what i can handle. I saw a video review testing cards on games like BF3 on ultra in wich HD 7770 were better then GTX 650 and i think that the nvidia one is costing a little bit more here. I just don't want to get stuck in low FPS after buying an expensive card. I wanna be sure i can run on max.

OP, the settings a GPU will offer is a more complex question than it may appear to be, because it's a question of bottlenecks.

A 7770 should be able to handle higher settings at a reasonable framerate. I would expect the card to be able to handle at least 40fps on all or mostly high (note I said high, not very high) settings, at 1080P, based on what I've seen from other similar cards. My 5850 was able to do a mixture of medium and high settings and maintain the nearly-60fps my CPU was able to net.

Which comes to why this is a complex question. The real question that you need to ask about the GPU is what settings it will be able to run before it bottlenecks the rest your PC. A 7770 may only be able to give you 30fps on the highest settings and 1080P, but if your CPU can only churn out 30fps anyways, then it's not an issue. If you have something like a 3570k or 3770k, on the other hand, and you're getting almost 60fps, the 7770 will only be able to keep up with that framerate at somewhat lower settings (again, perhaps a mixture of medium and high, which looks quite good).


Knowing what CPU you're running will help to better answer that question.

You should be fine. As of right now my 7850 is only a little faster then the 7770. However i suspect performance on both cards will improve and be consistent once (if ever) the game is optimized and dx11 is implemented

I'm looking to the third generation i3 (3220)

[Catamount]

That would be a decent CPU, although I think the FX-6300 would be a better chip, for around the same price ($10 more, but after motherboard differences, they should be the same price). The FX-6300 is equal to or better than the i3-3220 in almost any test, and in multithreaded apps, which includes MWO, it's a heck of a lot better, often as much as 50% better. It does consume something like 60W more, but really, what's 60W? Your entire system will still fall below 300W total at load (and probably won't exceed 200W).

It's just something to consider. Pair up an FX6300 with a 7770, and I imagine you'd get probably 35-45fps on all (or mostly) high settings @1080P, with somewhat better performance once DX11 comes out (slightly better maximums, and probably way better minimums once the CPU bottleneck is removed, so if I had to guess, maybe you'd get 50fps all the time on those same settings)). That's plenty to play a game like this and it would look good. With an i3-3220, you'd almost certainly lose some fps, because MWO is multithreaded, very CPU-intensive, and hates dual core CPUs as a rule.

Running an Asus HD7770 with an Ivy Bridge i7-3770 and 16gb of ram. All settings on maximum and usually pretty stable around 40fps.

When running around in my commando at 130kph I have seen some slight slow down but that may be because there are still some optimization issues.

[Catamount]

That sounds about right, Napes, given the current state of the game.

Thank you guys !
