CAL: ATI GPU 0: AMD Radeon HD 7870/7950/7970 series (Tahiti) (CAL version 1.4.1741, 2048MB, 1865MB available, 50 GFLOPS peak)

that's 7870 xt btw
edit 2: and yeah the os is debian 7
edit3: funny facts

it was working fine on old motherboard running ubuntu and some amd drivers taht i can't remember
i switched to debian to avoid bloat and cause my deluge started to segfault for no good reason, installed latest stable drivers from AMD site, but they couldn't recognize 7870 XT so i went with 13.3 beta, and after that i've been getting a lot of invalids

trying 13.2 beta now to see if it is any better (still reports 50 GFLOPS tho)
I do not have a 7870 and I use WIN 7, so I cannot give you a straight GFLOPS comparison. Your GFLOPS number of "50 GFlops peak" appears to be quite low. Here are my figures: 2 X 7970 each display = 11264 "GFLOPS peak"; 2 other X 7970 each display = 11776 "GFLOPS peak" and 2 X 7950 each display = 10750 "GFLOPS peak"
