OK, so first things first. I just (a few months ago) rebuilt my gaming rig after my mobo and cpu fried. I got a new graphics card as well (GTS250) since i had no way to test weather my old 9800gtx+ was any good or not. So my first question is; is it safe to test it (if it is fried) on my new mobo? ... and that leads into my main question. considering my mobo has 2 PCI express slots (but is NOT SLI ready, only crossfire), would it be beneficial for me to run both cards (say one for PhysX)? I game alot, and lately (BFBC2 Beta) I've been less than satisfied with performance. any advice would be appreciated, thanks.
