hi all did pick up a zotac 295 gtx over christmas and a little surprised.. the default specs seem to be 685 core. 1050 memory. 1455 shader. checked many websites and seem the default should be 576/1242/1008. anyone suggest a good stress test program as getting a BSOD sometimes playing AION with the Nvlddmkm.sys error coming up. best driver to use? thnx in advance.
