well, next time someone says they are getting 1000 fps on max shaders with 4 gtx titans in sli, they're probably bullstufftinggood to know anyways
Bearing in mind the last Athlons were made in 2005, that isn't much cpu power.
amd cards and processors are cheaper and generally worse in performance than the ehm, "proper" cards like intel or nvidia. like someone said one day"go big or go home" :-)
I am pretty sure a single Titan would reach 1000 fps on Blockland with max shaders with no bricks. I reach ~300 on my GTX 460 with no bricks on max.
$45 card as in it should be working better or as in it is working well? A $45 card can't be expected to run everything perfectly.
Just because it has a stuff ton of memory doesn't mean Titans are the gods of GPUs. It takes more than that: http://gpuboss.com/gpus/GeForce-GTX-TITAN-vs-GeForce-GTX-780I would never get a Titan. The GTX series is better suited for gaming and I bet that two GTX cards could easily beat two Titans.
