SLI GTX560 2gb enough or SLI GTX 580 3gb

Hi Guys

The time has come to build another good gaming PC.

Please tell me which setup will give the best performance in 2-way SLI for the 5760x1200 resolution?

GTX570s 1.2GB each
GTX560s 2GB each

I know that the GTX580s 3GB versions would be perfect in my case but they are too expensive

And the GTX 590 is week for 5760x1200

Also I’m aware that the overclocked GTX560 can perform as same as the stock GTX570, even a bit better than GTX570, plus the GTX560 has 800MB in reserve compared to GTX570.
Also I’m aware that the GTX560 runs cooler, consumes less power and less noisy

So, will the overclocked GTX560s 2GBs be good option for 5760x1200 resolutions with some low AAs/AFs?
Or should I keep saving the money for the GTX580 3GB versions?

The games I play: Race Driver Grid, Operation Flashpoint Dragon Rising, Total War series, Mettro 2033, h.a.w.k 2

I need your help guys, I’d very much appreciate it.

A typical gtx 560ti tops out around 920mhz up to 1050mhz depending on the model and brand. At 1ghz they are already drawing over 200w each close to the gtx 570 at the expense of life span. You have to crank up the volts close to max on most cards to be stable except for maybe msi but without vrm cooling they won't last but a few hundred to a few thousand hours.

gtx 570 isn't bad even when you consider the price but not all have their thermal pads properly applied and a few have been reported as blue smoke. Pop the cooler and mid plate add an extra layer of very thin and fine thermal pads that are similar to those that are stock so that there are not gaps. That will do a lot in the long run. Do not turn off ovp and ocp given the two fewer power phases to balance load compared to the gtx 580. Great overclocker when keept clean.

GTX 580 sli is very expensive but I wouldn't mind forking over the extra cash compared to a 590 knowing that if one died you can still get by and on their own offer a lot of performance.

gtx 590 no thanks and you already know how this card is your self. Old sparks and blue smoke on the old drivers.

i'd agree with nforce. i would personally save up a bit and go with the 580's (im running 2 in sli atm but no 3dsurround) both the 560 and 570's will give you more than enough performance to play all those games (except metro2033....) with that resolution. trying to play metro 2033 with 560's or even 570's in sli though... especially with that resolution.... you're pushin' your luck there..

so my advice is to wait and get some 580's.

I'd go with 6950 2GB's before the GTX 570's or 560's. The frame buffer will help at that resolution and they scale better than 570's.

Performance ranking for SLI/Crossfire: 580>6970>6950>570>560

Personally, I'd go with two 6950 2GB's and use the unlocked 6950 2GB bios for 6970 performance. It'll save you $500 over the GTX 580's while giving you the second best performance possible.

If you have all the money in the world, SLI some 580's. It'll need a bigger PSU too.

Have to give up physx and cuda if you go with AMD. And driver updates....

Yeah...LGA 1155 does leave the Crossfire/PhysX crowd hanging. X58 works great for that.

Many thanks for your valuable advices guys, you made it very clear for me.
So, i'm waiting until i have enough money for the GTX580s

All the best
