Crossfire 7770?

[gecko242]

So, I am gearing up for a long summer after GCSEs, and want to upgrade my slightly outdated rig to go along with a simpit i am planning to build. My specs are the following:

i3 3220
XFX R7770 (OC)
Corsair value ram (4GB)-Upgrading soon, hopefully to 8gb 1600mhz
CX 600w PSU
MSI z77 G43
WD Black 1TB


The question is what is bottlenecking? I am mainly playing KSP and Hawken, possibly with some war thunder mixed in. I can easily upgrade to a dual 7770 setup, which would also be relatively cheap, however dont want to do this if infact the CPU is the bottleneck...

Does anyone have any input on a dual 7770 setup, and if so how is it for multi-screen stuff? I will be running 3x(1280x1024) with a secondary 1024x768(i think) info monitor. I am not looking to run at max settings, just playable, above 30 framerates.

Many thanks.

I don't see a bottleneck. I'd suggest getting a better single card instead of cf'ing 7770's.

Also I think it would be better to get a new GPU

There won't be a bottleneck but crossfiring this cards is a it pointless, I'v tested it before and didn't gain much performance best thing is to get a newer gpu or maybe a secondhand one.

Also you might want to upgrade your ram to 8gb.

I run Crossfire 2GB 7770s and it's great, gives about 280 or 280X performance in games that crossfire scales well in

not worth crossfiring such a weak card

I would say try to fork out a little more on a better card, otherwise it should be a sturdy rig.

Ok, so many replies so quickly!!! 

 

My incentive for CF is that I allready have one, adn can get a second hand one for around 30 quid. I dont have 100 or so to drop on a decent second hand card. Basically what I am asking, is there any better route than going two 7770s for under 30 quid?

The i3 does not bottleneck your 7770.

 

I would only Crossfire the 7770 if getting a better single GPU is not affordable and the second 7770 is super cheap. It should give you good performance in well supported games.

 

The only other route would be to sell you current card and get a much better single one, but it depends if you can sell your current card for enough, a single card would be quite a bit more than 60 quid (30 spent on new 7770 + 30 for your current one). Your looking at more than 100 for something worth jumping too.

 

I would probably do the 7770 CF until you can save up to get something better.

Yeah, that was kind of my thinking. Cheers guys! One last question, Many sites talk of scaling from single to crossfire for single display, but how can this be interpreted for multi display setups? Is the scaling pretty much the same?

Scaling depends on the game. Higher resolution tends to give graphics cards more space to stretch their legs but a 7770 CF has plenty of 'space' to do so with 1080p.
