my second option is to sell my current GTX 560 (getting it replaced for a brand new one for free cause there was issues with the heat) - and with that i will have a total of around 350~400 dollars,
this will allow me to buy a GTX 570 assuming i do sell the GTX 560
so the question is, should i just go run the gtx 560 in sli, or buy a single gtx 570, and sli it later, or are the performances similar
is the performance difference between GTX 560 sli and GTX 570 sli that much of a difference that i should pay an extra 300 dollars for a second gtx 570
also what brand card should i get (exclude EVGA cause that cards 400 bucks and i dont want to pay a total of 800 bucks)
- warrenty isnt something im looking for, what i need is performance, reliability, and good cooling for sli
Their is quite a bit of an increase in performance from a GTX570 SLI and a GTX560SLI.Which may be worth the added cost($100) but I would suggest going for a newer gen card.For example a 7850 crossfire would be more powerful than a GTX570 SLI and it's cheaper.As well as having more RAM and a lower TDP.But if you favor Nvdia,their is also the GTX660 and GTX670 to think about which should be released sometime soon.
For the money,I think the 7850 is a very good choice.
hmm i see, maybe i should wait a little while for the 660, hopefully they get released soon, as for my psu, do you think a 750w psu would be suffice for an overclocked 4.5ghz cpu as well as 2x 660/ 670 ( assuming they consume the same if not, less amount of power as the 560 and 570)
1. The 570 is well known for a "shaky", in other words very weak reference design......if it's are reference 570 your getting an plan on doing any major OC'ing, don't be surprised when you smell something burning. The reference designs are just fine for "stock" speeds, but many have fried the VRM's on the PCB when overclocking due to relatively weak VRM. As a result, many vendors beefed up the VRM from the stick 6 phases to 8 and even 10 phases. If ya get one of these, hen you should be fine.
2. As for the relative performance, the 570 does substantially better in a single card configuration. The 560 Ti scales much better however and brings it up pretty darn close in SLI. In the end, I'd let th cost per frame numbers decide:
Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:
In SLI, the 900Mhz 560 Ti gets you just 11 fps than the 570's in SLI and just about 2/3's the cost per frame. Overclocked 10% at the factory with beefed up PCB's, 7 phase VRM's and larger more efficient coolers, they can be OCd a much as 30% over reference speeds.
So, as to your question ......
Two reference 560 Ti's for 792 fps and a $200 investment for the 2nd card
Two 900Mhz 560 Ti's for 862 fps and a $210 investment *
One 570 for 524 fps for $320 minus what ya get for your "used" card.
* (assumes you had one or can convince vendor to give ya one)
I'd take the twin 560's w/o a thought .... at worse it's a 51% performance increase over the 570 which at least in its "reference" design, is a bit shaky investment if you plan to do any significant overclock.
