Helo guys, I am building a computer and I wanted to buy a GTX 560Ti, but I had the opportunity to buy 3x radeon 5770 (two XFX and Sapphire Vapor X) to CrossFire for only R$110 (I live in brazil, so my currency is "reais" - R$110 = $65) more than a GTX 560Ti.
Now I doubt, if I buy the GTX 560Ti, in 1.5 / 2 years I intend to buy another to SLI GTX 560Ti and if Iget the three 5770, I will not be able to upgrade in the future ...
In addition, the 5770 is already an older card, so it should be hotter and it have a older GPU.
And I also intend to make a three monitor setup in the future...
What do you think is more worthwhile?
Intel Core i5 2500k
Corsair 4Gb 1333Mhz
ASRock P67 Extreme4
XFX 750w Black Edition
Samsung 1Tb 7200 RPM
Gravador de DVD - Gravador LG
Placa de rede - Pacific Network 150Mbps
WaterCooler - Antec kühler 620
Better to have a high end GPU than low end GPUs in CF.
As suggested above, the 3-Way CF is a great performance compared to a single GTX 560Ti but in order not to have a scaling issues, drivers issues and all the CF hassle Get the GTX 560Ti and SLI it in the future.
Also, if you're looking for Eyefinity, Eyefinity=AMD. the HD 6950 is slightly faster than GTX 560Ti and a single HD 6950 can drive up to 4 monitors.
