One GTX 580 1560ram or two GTX 560's 1GB ram SLI?

[enoch29]

I was thinking of purchasing one GTX580 during this sales week but I discovered two GTX560's at what looks like a better deal. Somebody showed me the charts and the two 560's SLI'd seem to outperform the single 580. I am concerned that the 560's only have 1GB ram while the 580 has higher.

How much does this ram effect my ability to crank up the settings while playing the top games like Battlefield 3?

Are two 560's 1gb ram a better deal?

Is there even a better possibility?

I have an i7 950, 1000wattsPSU, 8gb RAM(will be upgrading), pcie x16 motherboard (i believe) supports up to 4 crossfire and 3 SLI cards.


Looking for advise for this holiday season.

My thanks in advance.

2x HD6950's is a much better deal any way you decide to put it.

I've used 560 Tis in SLI as well as 580s (alone and in SLI), and I have to say, a single 580 is my personal preference. I run my games on a 120hz 1080p monitor, and my 580 has been perfect for everything. The 560 Tis were a bit faster on benchmarks, but honestly didn't run as smoothly. Not sure if the games I play sometimes don't work well with SLI, or if it's that whole microstutter thing. Anyway, 580 is my vote.

I'm also for the single 580.

SLI or CFX still seem to have issues with games when they first come out. If your all for waiting 2-3 weeks after a game comes out, for it to properly be working, then go for the crossfire or SLI.

charts don't tell you everything. get the 580.

Single 580 all the way

Put it this way. The two cards are still being seen by the system as two individual cards rather than one big rendering engine.

There are a lot of people on here that would swear by the two GTX 560 Ti's firmies over the GTX 580 and you have these gentelmen who love the 580. What it boils down to is personal prefrence. Either way you go, you will have some very good cards, and like they said what type of games you want to play and how many monitors you want to use. Everthing else on your system is awsome.

So? Mine have been fine and I have yet to see this microstutter that people keep whining about.
