GTX 770 vs GTX 580 - which one would be better for RF2

Hello

I am trying to buy new Graphics card, but I am faced to quite a bit of dilemma which one to buy,

Main reason why I wanna buy new card is Rfactor 2

I like GTX 580 more, but lots of people suggesting new GTX 770, I want to ask here as well, more opinion doesn't hurt

Can anyone tell me which one is better and why?

Thanks in advance

 

From what I have seen with the latest Silverstone release I would not recommend to buy a gfx card with less than 2GB RAM (GTX 580 has 1,5GB). Maybe in the future some modders decide to double the texture size for cars, 4096x4096 instead of 2048x2048, wich results in a texture size of 20MB per car instead 5MB, the math is quite simple. 30 cars x 5MB = 150MB for textures. 30cars x 20MB = 600MB for textures. With everything on max, 30 cars at Silverstone, the VRAM of my GTX670 2GB is completely filled. There is no room for additional 450MB. Maybe it is a good idea to go for a 4GB GTX770.

 

The Video Ram is a underrated feature most of the time but it's a typical limit for a good performance+quality balance. Getting a good GPU with a modest VRAM available can result in a bottleneck today, and not just in rF2. As Tosch just said all new generation games (not just racing titles) are loving the VRAM, improving both texture size (and/or quantity) and other visual effects loaded into vram (as shadows and other maps...). Even though rF2 is a scalable platform I would suggest to pick the 4GB GTX770 to, especially if you want more freedom of choice on the quality side.

 

nVidia naming works like this... a GTX 580 is:
series 5, 8 = high end.
770 is:
series 7, 7 = slightly less high end, but still high end.

As long as something has comparable RAM (for the reasons Tuttle already mentioned), the 770 is your best bet, it is two generations newer, and not lower end.

If you were comparing a 580 with a 720 (2 being a low end 7 series), then it might be a closer fight as far as the card itself goes.

 

Thanks for responses guys

Now I know what to choose

 

One more question if I am not disturbing you guys
These are my 2 choices

Evga is 2GB - Gigabyte is 4GB
Normally 4GB should be better but some people says 2GB EVGA is a top choice, any opinion about it?

Thanks

 

EVGA has stock cooler. For the cooling system alone I would pick the Gigabyte. Less noise and better overclocking. The new nvidia cards reduce the boost clock if gpu temp exceeds 70°C and atm (summer in Germany) it happens all the time to my GTX670.

 

Is this discussion all assuming single screen or triples?

 

Thanks again guys

Galaga
Single screen

 

This past week I picked up a 760 (one step down from the 770) to run (single card) 3 monitors. I can't max out the graphics, but the frame rates are fine. 50-60 FPS in rF2. I got the EVGA 4GB 760 and I couldn't be happier with my purchase. The way it was explained to me- VERY ROUGHLY-
580=670=760 Go up in 1 generation, go down 1 in series for equal performance. This is a gross simplification. But all else being equal, go for the 770, it'll out-perform the 580 and the latest chipset will have features that the older chipset will not.

 

Very nice info here thanks!

 

Just replaced my 2 580 gtx's for a 780 gtx and very happy. runs faster athough acording to 3d mark site they score the same (580 sli v single 780). only running one screen but have everything in settings on full. get great f rates but that changes from track to track. 3d with glasses is good, the cooling setup is super quiet, no thundering fan noises anymore. i have the evga overclocked 780 and aparently its as good as the stock titan.(dont quote me on that) it has 3g of ram and dose the job well. some time down the track may pick up another one and two more screens.

I did the same -from 2x580's to a sinke Titan (pretty much the same as a 780 ) yes much nicer setup, I'll never go back to duel gpu again, if ou can get hold of a 120hz monitor then 3d vision has to be the way for you now

 

got a new monitor just before i got the 780. an ASUS VG278HR. top res is 1920 x 1080 x 120hz.(has built in nvidia 3d setup) 20+ car race starts and no stuttering frame rates. im happy.

 

Hi, new user and just thinking about getting rF2

This has all been very helpful for me.
I have just built a new system with i7 3770k, 8GB corsair on a P8Z77-V Pro board but I didn't really spend too much on the card. £90 for a 2GB HD7770 Ghz edition. It's not really running that great.

I'm in the market for a new card and I'm thinking between the 770GTX or the 780GTX

There is a fair difference in price between the two but there is also a large performance gap between them too.

Have any of you tried the two cards, (or have any insight), or could anyone confirm if the game will utilise the 780GTX better over the 770?

 

I recently bought a new PC just for rFactor 2:

i7 4770k
16gb RAM (1600mhz)
128 SSD (Plextor M5)
Gigabyte GTX 770 GDDR5-4GB (GV-N770OC-4GD)

I haven't done a fps test, but I'm telling you now, it can run anything you throw at it in the current build with NO slow down at all, even at Monaco etc with a 30+ car grid etc.

P.S. That's on Max settings for everything at 1920x1080 45 degree FOV on 1 monitor and max AA etc and settings in the launcher too.

 

Wow!

So I'd probably need to up my ram to 16GB too?

So, the GTX 770 4GB sounds good then.

 

Not sure about the general RAM to be honest, but as mentioned by Tim (who I'd listen to as he makes the game), the Video RAM is more important these days than it used to be.

If you want more details on my full system, I got it from Novatech:

http://www.novatech.co.uk/products/pcs/bb-47708b.html

and then added the gfx card and SSD.

Your processor is more than enough and your RAM is a decent brand (mine's probably a 'no name' brand, I haven't checked).

 

Cool, so more VRAM is the way forward then.

I got an Intel SSD too so the read times from disc shouldn't be too much of an issue, although when I bought the disc it was cutting edge, but at only 3.0GB/s sata, it's yesterday's news now it's 6GB/s sata on my new Motherboard...

I'll look into the GTX770 4GB, still trying to get the balls to plump up for a GTX780 as it would be a bit more to spend but could last me a little longer...

 

8 GB RAM is more than enough right now for rF2. In fact I believe it is a 32bit program and so it can't address more than 4GB anyway.
