hello Mantis, thanks for answer.
I was so afraid u will tell me that, i have core on 1000mhz so i guess its not that with 950 in name. They cant help me there but ok i will try it :- / is there at least chance there are those cards with different serial number and with different bios? I did backup and i know i have GV-N560SO-1GI.F3 so can i found there guy with GV-N560SO-1GI.F4 for example?
Ok, so...i go to make post on cz forum now also order me some fancy ati and make advertisement to sell this one.
Funny thing on this all is before this one i had gtx260 which stoppped working after 2 years giving me incredible artefacts in games, before that i had ati hd4870 which was crashing in stalker and also i found out on forums i need new bios and while flashing it crashed and since then that ati is just sitting on my shelf, thats how lucky iam!!
