Ok let's clear this up.
This is an AMD HD7970 GPU, close to the top of the range on todays GPU market. It retails for £320+ alone, depending on the version.
Now here are some benchmarks for Battlefield 3 running at 5760x1080 resolution with ultra settings and also compared to the comparative priced GTX 680.
Note that the top two results are SLI and Crossfire,
TWO of those cards running together. Total cost = £600+. They don't even manage 60fps with AA turned on, the single cards barely manage 30fps.
That is at 5760x1080 resolution. Number of pixels total - 6,220,800.
Now 4k, if you take the 3840 x 2160 UHDTV spec and what PD are sampling GT5 at, number of pixels total = 8,294,400. That's a 33% increase in pixel density.
So in conclusion if a £330 GPU cannot manage 30fps with that resolution how on earth is a GPU much less powerful and cheaper going to manage that + a 33% increase in pixel density?Click to expand...
