another what card/s thread.

[umboma]

Hello again guys,

So I have £350 to buy a new GPU, after some recommendations on here im still lost as to what to get:

I'm thinking about getting x2 660 in sli as that will give me better performance for £340 then what a 680 will for £420 saving me £80.

Or

For the £340 I could get a 670 but obviously it's not as good as a 680 but the 660 will be in sli.


I suppose my question is why shouldn't I get 2 660's and sli them for greater performance over just buying a single more powerful card?

Is there specific games you play incase some prefer single / multi cards. Also what resolution are you playing at? What power supply do you have?

I think it generally comes down to personal preference, however the general consensus is to get the best single gpu for performance as you can as multiple gpus can lead to headache and the scaling tends to differ from a game to game basis and heavily relies on drivers having any problems worked out .

I have a 750W XFX psu, games well, a bit of everything really, crysis 3, witcher 2, hitman, is what I'm playing at the mo, I also game at 1080P

The 660 only has a 192bit bus, thats not great for SLI.

Also, why a 680? that really expensive for 1080P, a 670 is just as good, or better yet a 7950.

I thought this too, but after reading tons of reviews the problems what SLI had a few years ago are almost non existent now, drivers are a lot more polished and in worst case scenario you just have to wait a few weeks for the drivers to be updated or just run on one card for a little bit and run the second card for PhysX.

this is what i don't get, the 660 in sli out perform a 680 so it will also out do a 670 for the same price. Isnt the bus only important if I want to go higher then my current resolution 1080P

It will where the SLI profile is good, which isn't always the case, when its not it could be as slow as, well... a GTX 660.

Also, you take the game res above 1920 x 1080P, like 2560 x 1440P or higher and that 192Bit bus will chock it to death, it will very quickly come to a grinding slow down.

So the 256Bit bus on the 670/80 is a better thing to have.

I plan to stay with 1080P so 192bus is ok?

Yes, it should be ok. but if it was me i wouldn't be spending that much money on one GPU let alone two with a 192Bit bus, even at 1080P.

Its on the limit for 1080P now, so who knows what effect it might have with future titles.

IMO it doesn't belong on a GPU in that price range.

Go for 670 or 7950 at that price..
