did anyone read the reviews by Tom's? the Powercolor 7870 LE pcs+ myst edition is the only card labeled 7870 but with a tahiti core. Tom's used it in all of their SBM computers, it has a best buy from Tom's and was in the best graphics cards for February. You get near or past stock 7950 performance without boost for only ~$240
*Edit with overclocking the card reaches non boost 7950 performance with the risk of a lot of power usage as well, but Tom's has had several of these cards about 4-5 of them, all have overclocked well, and cooling noise was mediocre-decent, no the worst though.
